A delta forms when a river enters a standing body of water and its velocity decreases, causing sediment deposition. As fresh river water mixes with salt water, flocculation occurs, causing fine particles to sink out of suspension. Deltas form where deposition exceeds sediment removal. Deltas are composed of topset, foreset, and bottomset beds and can be arcuate, bird's foot, or cuspate shapes.

Deltas- types, formation, case studies
Deltas are landforms formed at river mouths where sediment is deposited as the river enters a sea or lake. They are fan-shaped areas that can span hundreds of kilometers. The Indus River Delta in Pakistan covers 40,000 square kilometers and has a complex network of distributaries. Deltas form as rivers slow down at their mouths, causing sediment to flocculate and settle, building up over time. Different types of deltas include bird's foot, arcuate, and cuspate shapes, depending on factors like tidal influence. Deltas provide fertile land and resources but are also at high risk of flooding and channel migration due to their unstable sediments.
Delta’s
Deltas form where rivers enter standing bodies of water and experience a drop in velocity, causing sediment deposition. Sediment is deposited in three layers - topset beds of larger particles, foreset beds of medium particles, and bottomset beds of finest particles. Delta shapes include arcuate, birds foot, and cuspate. The Nile Delta is an example of an arcuate delta with its curving shoreline. The Mississippi Delta resembles a birds foot with distributary fingers. The Ebro River Delta in Spain has a cuspate, tooth-like shape from opposing currents.
Delta formation
The document discusses different types of river deltas, which are areas of sediment deposited at river mouths where flowing water enters a slower body of water. Deltas form when the river's sediment load deposition rate exceeds the erosion rate in areas where rivers discharge into seas or lakes with little wave action. Common delta types include arcuate deltas with rounded edges, cuspate deltas resembling teeth, and bird's foot deltas with many branching sediment-bounded channels fanning out.
River 3 delta meander impacts
The document describes the formation of deltas. As a river reaches the sea, it deposits sediments, building up the river mouth and causing the river to split into distributaries. Over time, accumulated sediments rise above the water level, forming a delta where the river meets the sea. The document also discusses river meanders, which form as a winding river erodes its outer banks and deposits sediments on its inner banks. Finally, the document notes some positive impacts of rivers in providing water and transportation and some negative impacts as flooding can endanger lives and contaminated water can spread disease.
Delta
A delta is a landform formed at the mouth of a river where it empties into a standing body of water, such as an ocean or sea. Deposition occurs as the river's velocity decreases and it can no longer carry its sediment load, causing the sediment to settle out and form the delta. Deltas take on various shapes like arcuate, birds foot, or cuspate depending on factors like tidal patterns or river flow. Common examples include the arcuate Nile Delta in Egypt and the birds foot Mississippi Delta in the United States.
Ganges Delta
The document discusses the Bangladesh Delta and the processes involved in delta formation. It defines key terms like source, mouth, estuary, and delta. It explains that rivers erode, transport, and deposit material. The Ganges Delta is used as a case study. The delta was formed as the Ganges and its tributaries transported sediment from the Himalayas and deposited it in the Bay of Bengal, building up land above sea level over time due to factors like decreasing gradient and flow speed.
Deltaic systems usmaan
This document is a presentation on deltaic systems given by UsMaan Sikandar to Professor Dr. Shahid Ghazi at the Institute of Geology at Punjab University Lahore. It introduces deltas and their classification, including fluvial, tide, wave, and mixed process dominated deltas. It describes the physiographic characteristics of deltas and provides examples of ancient and modern delta systems like the Indus River Delta. The presentation concludes that deltas provide important paleoclimate indicators and reservoirs for resources while noting characteristics of modern deltas can inform understanding of ancient formations.
Braided channels
A braided channel consists of a network of smaller interconnected channels separated by small, temporary islands called eyots or braid bars. Braiding occurs when a river's sediment load and slope exceeds a threshold, causing deposition that divides the channel. This often happens after heavy rainfall, when discharge levels fluctuate. Braided channels are common where coarse sediments like sand and gravel are carried, such as in the wide, shallow valleys of rivers with little slope.

River Presentation
The document discusses river processes and landforms created by erosion, transportation, and deposition of sediment. Key points include:
- Rivers erode, transport, and deposit sediment through various processes including saltation, traction, suspension, and solution that create landforms such as potholes, rapids, waterfalls, deltas, and floodplains.
- The Hjulstrom curve shows the relationship between sediment size, erosion thresholds, and transportation/deposition based on water velocity.
- Meandering rivers create oxbow lakes through lateral erosion and cut-offs of meander loops over time.
River
The document summarizes key aspects of river systems, including the hydrologic cycle, stream characteristics, erosion and deposition processes, landforms created in the upper, middle, and lower courses of rivers, and human impacts on rivers. It describes evaporation and precipitation cycles, stream velocity and types, erosion by abrasion and hydraulic action, transportation methods, meander formation, floodplain and levee development, and delta building where rivers enter seas. Finally, it discusses human reliance on and interference with rivers through activities like transportation, agriculture, power generation, and pollution.
Fluvial Process And Related Land Forms
The document discusses fluvial processes and landforms. It describes various types of erosion caused by water including surface erosion through splash and sheet erosion, and channel erosion through rills, gullies, and streams. It also discusses drainage basins and patterns, explaining how drainage patterns are influenced by geology and reflect the arrangement of river courses. Various landforms resulting from fluvial processes are also mentioned.
L4 Levees And Floodplains
1) Floodplains form through erosion and deposition as rivers carry large loads of sediment and widen their valleys over thousands of years.
2) Levees are natural embankments that form along rivers when water moving out of the channel loses energy and deposits heavier sediments along the banks during flooding.
3) Repeated flooding and deposition over time cause levees and floodplains to build up layers of nutrient-rich alluvium soil.
River Landform
Rivers have distinct features along their upper, middle, and lower courses. In the upper course, the river flows through a V-shaped valley with steep sides, eroding vertically. Meanders begin to form in the middle course as the river erodes more horizontally and widens the valley floor. In the lower course, the river flows through a wide, flat floodplain with features like oxbow lakes formed from abandoned meander loops.
39124452 geomorphology -_landforms_of_fluvial_erosion
1) Waterfalls form in the upper course of a river where the river bed slopes steeply. Features of waterfalls include steep drops in elevation, strong currents, and an inability to move upstream.
2) Rapids form where river flow is swift and turbulent. Repeated erosion by swift water has produced rounded river stones and rocks.
3) Meanders form in the middle and lower courses where the river bed slopes more gently. Meanders migrate downstream over time through cutoffs, eventually leaving oxbow lakes behind.
Fluvial
This document provides information about fluvial and alluvial fan systems. It begins with an introduction to why fluvial systems are studied and describes their organization into drainage basins. It then discusses the morphology of rivers and floodplains. The rest of the document describes various fluvial environments like bars, channels, overbank areas and different channel patterns for braided, meandering and anastomosing rivers. It also discusses alluvial fans and their facies. In summary, the document outlines fluvial system components, morphologies and depositional environments to understand sediment transport and deposition.
Tvc fluvial processes
Here are some suggestions for how to represent the river processes visually using diagrams:
Solution - Draw water droplets with dissolved minerals
Suspension - Draw particles floating in the water current
Saltation - Draw particles bouncing along the river bed
Traction - Draw larger particles being rolled along the river bed
You could also draw:
Erosion - Show particles being scraped from the river bed/banks
Transportation - Arrows showing movement of particles downstream
Deposition - Build up of particles settling out of the water
Landforms - Simple sketches of meanders, ox-bow lakes, deltas etc.
Let me know if any of these ideas are helpful or if you need any other suggestions!
Features formed by a river
The document discusses features formed by rivers in different parts of their courses. It describes how waterfalls are formed in the upper course when a harder rock overlays a softer rock, causing the softer rock to erode away and form a ledge and plunge pool. In the middle course, features like meanders and slip-off slopes can form as the river energy decreases and causes deposition along banks into bends.
Meander Formation
Meanders form through the process of helicoidal flow. At bends in the river, centripetal force throws water towards the outer bank, eroding and undercutting it. Slower flow on the inside of bends leads to deposition and the formation of point bars. Helicoidal flow causes eroded material to be deposited downstream in the next meander loop, furthering the meandering shape over time as the river seeks the most efficient path.
sedimentary environment (fluvial channel)
This document outlines the key aspects of fluvial channels and deposits. It discusses the origin and stages of river development from mountainous sources. The main forms of fluvial channels are straight, anastomosing, braided, and meandering, with braided bars and point bars being the main deposits. Fluvial deposits have economic importance as aquifers, reservoirs, and hosts for minerals like gold. In conclusion, the presentation covered the origin, forms, deposits, and economic value of fluvial systems.
8 River Landforms
The document discusses various river landforms found along different parts of a river's course. It defines key terms like load, sediment, river bed, and river bank. It also defines the four types of erosion and four types of sediment transport processes. The document describes how particle size, channel width, and depth change downstream. It then provides more details on specific landforms usually seen in the upper, middle, and lower course, such as V-shaped valleys, waterfalls, meanders, point bars, oxbow lakes, and deltas.
Types of Rivers
The drainage pattern shown is dendritic. A dendritic drainage pattern occurs in regions where the underlying rock is uniform in its resistance to erosion. It resembles the branching pattern of a tree, with many small tributaries that join together into larger streams and rivers, eventually converging to a single outlet. The branching tributaries meet the main rivers at acute angles. This type of drainage pattern suggests an underlying topography that has a uniform resistance to erosion, allowing the drainage network to develop evenly in all directions without being controlled by the geology.
Present Condition of Meghna River
An informative and brief description of river bank erosion, water quality, sediment quality, sediment load, and hydro-meteorological scenarios of Meghna River in Bangladesh.
Levees
Levees are naturally occurring ridges along river banks that are formed above the level of the floodplain. When a river floods, it leaves sediment thickest at the channel edges which raises the level of the banks, creating levees. Repeated flooding further increases the height of levees as more sediment is deposited, leaving the land within protected during subsequent floods.

Genghis Khan
Temujin, who would later be known as Genghis Khan, was born in 1155 to a noble family in Mongolia. After his father's death, his family fell into poverty and he had to fight for survival. Over time, Temujin united the Mongol tribes and established himself as a powerful leader. He then conquered neighboring territories including Western Xia, Jin China, and the Khwarezmid Empire through effective military strategy. Genghis Khan died in 1227 after defeating the Tangut Western Xia dynasty who had betrayed their alliance.
Hijrah
1) Hijrah is obligatory for those unable to manifest or establish their religion and able to migrate.
2) It is not obligatory for those with difficulty migrating, like the weak, sick, or those forced to remain.
3) It is recommended for those able to practice their religion where they are.
4) The Prophet (SAW) and companions migrated to escape persecution in Makkah and establish Islam freely in Madina with Muslim protection. This set the example for obligatory hijrah.

Tipu sultan
Tipu Sultan was a ruler of Mysore in late 18th century India who fought vigorously against British colonialism. He modernized his army with French assistance and developed advanced rocket technology. Tipu corresponded with foreign leaders seeking support against the British but ultimately failed to secure sufficient aid. Despite accusations of mistreating Hindus, historical accounts indicate Tipu donated generously to Hindu temples and instituted religious tolerance. He was an innovative leader who helped develop Mysore's economy, infrastructure, and horticulture. However, Tipu was eventually defeated by the British in battle and died defending his kingdom of Srirangapatna in 1799.

Tipu Sultan was a legendary ruler of Mysore who opposed British rule in South India in the late 18th century. He fought the British in the First and Second Anglo-Mysore Wars and dictated terms to the British in subsequent treaties. After his father Hyder Ali died, Tipu became the ruler of Mysore and focused on advancing his military, especially Mysorean rockets. However, the British remained a threat and the Fourth Anglo-Mysore War in 1799 resulted in Tipu's death during the Battle of Srirangapatna, bringing British rule to Mysore.
Genghis khan and_mongols
Genghis Khan united the Mongol tribes and built a vast empire through conquest. He was tolerant of different religions and his military strategies of feigned retreat and attacks on horseback allowed him to defeat larger armies. After his death, the Mongol Empire continued expanding under other leaders but grew too large to manage and eventually fractured into khanates. The empire had both positive impacts like increased trade and negative ones as many regions suffered destruction from Mongol invasions.
Corries
The document describes the formation of cirques and corrie lakes through glacial erosion processes. At high altitudes, snow accumulates in hollows and is compressed into firn and eventually ice by additional snowfall. The weight of the ice causes it to erode the surrounding bedrock through plucking and abrasion, widening the hollow over time into a characteristic armchair shape. Weathering further down also contributes to erosion. As the glacier melts, a corrie lake sometimes remains behind, contained by the rock lip formed from deposited debris.
U shaped valley
U shaped valleys are formed when glaciers erode and widen existing V-shaped river valleys, leaving behind a wider U-shape. Glaciers overdeepen and scour the sides and bottom of valleys, changing their original V-shape formed by rivers into a broader U-shape through erosion.

Genghis Khan
Genghis Khan was the first emperor of the Yuan Dynasty who was born in 1162 in Mongolia and subjected over 1 million people during his rule from 1206 to 1227, establishing a vast empire through military conquest before his cause of death was unknown in 1227 when he asked to be buried without markings.
Genghis khan
Genghis Khan founded the Mongol Empire, one of the largest and most powerful empires in history. He conquered vast territories across Asia, including all of China and areas west to Afghanistan before dying while battling another group. The Mongols succeeded through tactical brilliance and psychological warfare. They studied their enemy's weaknesses and used maneuvers like feigned retreats to draw opponents into traps. Through continued expansion after Genghis Khan's death led by his progeny, the Mongol Empire reached its peak under Kublai Khan in the late 13th century, becoming the largest contiguous empire in world history.
Genghis Khan
Genghis Khan was born in 1162-1167 in Mongolia and became a powerful tribal leader and king. He united the nomadic tribes of Northeast Asia and created the largest contiguous empire in history. Genghis Khan was a fierce warrior who conquered many lands through military victories but also established schools, cities, and shared his wealth with his people. He is still remembered today through monuments, places named after him, and for transforming Mongolia into a major power.

It provides accounts from Christian missionaries, historians, and Muslim officials describing large-scale massacres of Hindus, destruction of Hindu temples, and the enslavement and forced conversion of Hindus under Tipu Sultan and Hyder Ali's rule. The document argues that constructing memorials for Tipu Sultan and Hyder Ali would insult the Tamil people given the persecution of Hindus that occurred during their time.
river delta impact (For Geography)
The document describes the formation of deltas. As a river reaches the sea, it deposits sediments, building up the river mouth and causing the river to split into distributaries. Over time, accumulated sediments rise above the water level, forming a delta where the river meets the sea. It also discusses how meanders form through a river's winding course as it seeks to avoid obstacles at a low gradient, eroding the outer concave bank and depositing sediments to form slip-off slopes on the inner convex bank. Rivers provide benefits like water and food but can also negatively impact people through flooding and spreading disease.
Genghis khan
Genghis Khan, originally named Temujin, united many tribes in Mongolia and went on to build a massive empire through military conquest. After his father was poisoned by a rival tribe, Temujin worked to become the leader of his tribe. He married Borte and had four sons. By the age of 20, Temujin had built a large army and began conquering surrounding lands, taking the name Genghis Khan. His Mongol Empire eventually became the largest contiguous empire in history and included parts of China, Central Asia, Middle East and Europe.

River channel processes
1. Rivers carry out three main processes - erosion, transportation, and deposition. Erosion occurs as rivers wear away land, transportation is the movement of eroded sediments downstream, and deposition happens when sediments settle out of the river.
2. The speed of a river's flow is determined by factors like discharge, channel shape, roughness, slope, and gradient. Faster flows lead to turbulent patterns that can transport larger sediments, while slower flows result in deposition of sediments.
3. Rivers erode their channels through hydraulic action, corrasion, attrition, and solution. Sediments are transported in different ways depending on their size - through traction, saltation, or suspension. When flow speeds decrease,

CAMBRIDGE GEOGRAPHY AS - HYDROLOGY AND FLUVIAL GEOMORPHOLOGY: 1.3 RIVER CHANN...
Subchapter 3 in the first chapter of Hydrology and Fluvial Geomorphology, suitable for AS students, consisting in the following: river processes, velocity, flows and Hjulstrom Curve.
Running water-Geomorhology Chapter
Running water is the primary agent of erosion on Earth's surface, though its role is limited in some glaciated and desert areas. Streams erode through processes like abrasion, attrition, solution, and hydraulic action. As they flow downhill, their kinetic energy is used to transport sediment in suspension, saltation, traction, or solution. When the stream's energy decreases, such as when entering flatter terrain, sediment is deposited in features like point bars, floodplains, levees, meanders, and deltas. Meanders may be cut off over time, forming oxbow lakes.
Fluvial processes and_land_forms
Streams shape the land through erosion and deposition via fluvial processes. A stream system typically has three courses - upper, middle, and lower. The upper course has steep valleys and gorges due to erosion. The middle course features meandering streams and floodplains. The lower course is dominated by depositional landforms like deltas. A stream erodes until it reaches its base level, which can be an ocean, lake, or resistant rock layer.
Sec 3 Rivers
The document discusses various topics related to river drainage basins and processes:
1. It defines a drainage basin as an area of land drained by a river and its tributaries, with watersheds separating adjacent basins.
2. River patterns like dendritic, trellis, and radial are described as related to the underlying rock types.
3. Factors like river velocity, volume, and energy are discussed in relation to gradient, channel roughness, shape, basin size, vegetation, and climate.
Marginal marine depositional environments
This document discusses marginal marine depositional environments including deltas, beaches, barrier island systems, and estuaries. Deltas form where rivers enter standing bodies of water, depositing topset, foreset, and bottomset beds. Beaches have foreshores, backshores, and berms that change with seasons. Barrier islands are long and narrow, separated from the mainland by lagoons. Estuaries are coastal waters where rivers meet the sea, and can be wave-dominated or tide-dominated based on wave and tidal energy influences on sediment transport.
Rivers presentation
Rivers and streams begin as small tributaries that merge to form larger rivers as they flow downhill towards areas of lower elevation. They perform erosion by processes such as attrition, corrasion, hydraulic action, and chemical solution, and transport sediment through dissolution, suspension, and along the stream bed. A stream's competence and capacity determine the size of materials it can carry. Channel morphology depends on factors like gradient and sediment load, resulting in narrow channels in steep upper reaches and wider braided or meandering patterns downstream. Within channels, features like bars, point bars, and floodplains form through sediment deposition during times of changing flow.
Fluvial/River Processes
Here are the key points about how isostatic changes have impacted the Irish landscape:
- Isostatic changes refer to vertical movements of the Earth's crust due to adjustments in land masses following the melting of ice sheets during glacial periods.
- During the last ice age, much of Ireland was depressed under thick ice sheets, weighing the land surface down. As the ice melted about 10,000 years ago, the land began to rise again in a process known as isostatic rebound.
- This caused rivers to be elevated above their original base levels. Many rivers underwent rejuvenation as they cut downwards, forming features like waterfalls, incised meanders and terraces along their courses as they
River Channel Processes & Landforms
The document discusses river channel processes and landforms, including:
1. River processes like erosion, transportation, and deposition shape landforms through sediment movement.
2. Velocity and discharge impact a river's ability to erode, transport, or deposit materials based on the Hjulström curve.
3. Meanders, floodplains, and deltas are examples of landforms formed by fluvial erosion and deposition that impact human settlements.
Delta_Roy.ppsx
This document discusses deltaic depositional environments. It defines deltas and differentiates them from estuaries and river mouths. The key types of deltas are described as being river-dominated, wave-dominated, or tide-dominated. Characteristics and controlling processes of each type are provided, along with examples. The shapes, sub-environments, structures, lithofacies, and characteristics of deltaic deposits are outlined. Ancient deltas are described as thick clastic successions that fine upward from offshore to fluvial facies.
1.3 river channel processes
1. The document defines key terms related to river channel processes including abrasion, attrition, capacity, competence, deltas, discharge, gorges, helicoidal flow, hydraulic action, laminar flow, levees, load, point bars, pools, riffles, river cliffs, solution, turbulent flow, waterfalls, and rapids.
2. It discusses factors that affect rates of erosion in river channels including load, velocity, gradient, geology, pH, and human impact.
3. The main types of river channel flow are laminar, turbulent, and helicoidal flow while channel types include straight, meandering, and braided channels. Meanders have asymmetric cross-sections
Simplified Models.ppt
Deltaic systems are subdivided into subaerial plain, delta front, and prodelta facies associations. Deltas form during regressive periods as sediment is deposited where rivers enter standing bodies of water. As flow decreases in velocity, channel bifurcation occurs as sediment is deposited around the channel mouth in bars, repeating to form multiple smaller channels. Deltas can be identified by thick accumulations of terrigenous sediment interfingering with fluvial and marine deposits. Splays develop within flooded areas, filling space between distributary channels. Delta morphology depends on a balance between river, wave, and tidal influences.
Naturalists at Large: Rivers watersheds
The streams found in mountains are likely young, with V-shaped valleys and steep gradients. They move fast upstream, carrying large rocks and boulders, but slow downstream where they deposit small silts and clays. This sorting process forms the soils in valleys. Grand Canyon took 1-3 million years to form as the river cut through rock. Rivers slow and widen as they approach base level, forming broad floodplains and meanders.
Work's of river, winds, seas and their Engineering Importance
The document summarizes key concepts regarding rivers, wind, and seas and their engineering importance. It describes rivers' erosion, transportation, and deposition functions according to Playfair's Law. It discusses the juvenile, mature, and old stages of river development.

Rivers
The document discusses rivers, including their definition, formation, and key processes. It notes that rivers are natural flowing watercourses that drain into oceans, lakes, or other bodies of water. Small rivers may have other names like stream or creek. Rivers form through the hydrological cycle as water collects from precipitation through drainage basins. The main processes in rivers are erosion, transportation, and deposition, which are driven by the river's energy. Erosion can make a river wider, deeper, or longer through various types of erosion. Transported materials are eventually deposited through sedimentation.
Coastal Depositional Systems.ppt
Deltas form where rivers enter standing bodies of water and include mixtures of fluvial and marine deposits. They can be divided into three subsystems: the upper delta plain containing fluvial and marsh deposits, the delta front with distributary channels and tidal deposits, and the lower prodelta with suspended sediment deposits. The morphology and deposits of a delta depend on the relative influences of river discharge, waves, and tides.
River erosion
This document outlines key features of river erosion and river systems. It begins with a longitudinal profile diagram showing how a river's gradient is steepest at the headwaters and gentlest near the base level. It then discusses drainage patterns like dendritic and trellis. Common river features like meanders and waterfalls are also explained. The document covers the erosional work of rivers through processes like abrasion and hydraulic action. Methods of sediment transportation like suspension and traction are outlined. Stages in river development from youthful to mature to old age are also summarized.

Destructive plate boundaries
This document summarizes the three types of plate boundaries:
1) When an oceanic plate meets a continental plate, the oceanic plate is subducted beneath the continental plate. This can form deep trenches and volcanic island arcs.
2) When two oceanic plates meet, one plate subducts beneath the other, forming ocean trenches and island arcs offshore.
3) When two continental plates meet, they are forced upwards to form fold mountains rather than subducting. This leads to earthquakes but no volcanic activity. Mountain ranges like the Himalayas and Andes are examples of this type of plate boundary.
Out of Town Shopping Centres
Merry Hill shopping centre was built between 1984-1989 on the site of the former Round Oak Steelworks in Brierley Hill. It has over 185 shops and attracts many shoppers with its large stores and 10,000 free parking spaces. However, it had negative impacts on surrounding towns like Dudley, leading to high vacancy rates and declining trade in their town centres. Future plans aim to connect Merry Hill to Brierley Hill town centre and redevelop the area with new leisure facilities, housing, and businesses to better integrate the shopping centre.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Delta
- 2. A delta is a feature of deposition formed when a river flows into a standing body of water Deposition occurs as the velocity drops on entering the standing body of water, this reducing the capacity and competence of the river bedload and suspended material are ‘dumped’
- 3. Delta’s form when velocity drops as the river enters a standing body of water, typically this is at the coast as the river flows into the sea An example of a delta formed when a river flows into the sea in south west Greenland
- 4. Flocculation occurs as fresh water mixes with salt water - e.g where a river flows into the sea -(then called brackish water), and is the process by which tiny particles in suspension like clay and silt (which under normal fresh water conditions would likely never fall out of suspension) coagulate with the salt in the water by chemical reaction and become heavy enough to ‘sink’ and be deposited
- 5. Deltas only form where rate of deposition exceeds rate of sediment removal – i.e. Where the critical threshold is no longer met and the system has fallen out of dynamic equilibrium. These conditions are likely where: The calibre of the load of the river is very large (therefore requiring a high amount of energy to keep in transport) The costal area into which the river dumps its load has a small tidal range and weak currents meaning there is limited wave action and therefore little subsequent transport of sediment taking place after its initial deposition allowing large deltas to form
- 6. Delta’s are usually composed of three types of deposit Topset beds: The larger and heavier particles are the first to be deposited as the river looses energy Foreset beds: Medium calibre particles travel a little further before they are deposited as more steep angled ‘wedges’ of sediment Bottomset Beds: The very finest particles travel the furthest before very low velocity/flocculation leads to their deposition
