CAMBRIDGE GEOGRAPHY AS - HYDROLOGY AND FLUVIAL GEOMORPHOLOGY: 1.3 RIVER CHANN...George Dumitrache
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.
Geological action of river or Fluvial processes
The geological action of river is divided chiefly into three parts as Erosion, Transportation and Deposition.
Erosion: River erosion is mainly due to mechanical breaking down of rock fragment. The chemical action of
rivers is minimal. A wide variety of processes are involved in river erosion as follows;
a. Hydraulic action: It is the process of mechanical loosening or removal of the material by the action of the water
alone. The effectiveness of hydraulic action of a river is depends on gradient, velocity of the stream, width, depth
and shape of the channel and discharge.
b. Abrasion: The process of wearing-away of bed rock surfaces by mechanical processes such as rubbing, cutting,
scratching, grinding and polishing etc. is known as abrasion.
c. Attrition: The process of mechanical wearing and tearing of the transported rock fragments into smaller fragments
due to mutual impact and collision.
d. Cavitation: Highly turbulent rivers in rocky channels erode their beds by hydraulic plucking, in which pieces of
bed rocks are lifted out by strong eddies spiraling up around vertical axes. This sucking out of the rock pieces
produces cavities or depressions within the rock. This type of process is called cavitation.
e. Corrosion: The chemical processes of rock erosion by river water are known as corrosion or solution.
Important erosional features:
a. Potholes: These are cylindrical or bowl-like depressions in the rocky beds of streams, which are excavated in the
floors of the streams by extensive, localized abrasion. These are commonly found in softer bedrocks.
b. Water fall: These are defined as magnificent jumps made by stream or river water at certain specific parts of their
course where there is a sudden and considerable drop in the gradient of the channel.
c. River valleys: The river channel carved out by the flow of running water is commonly known as a river valley.
d. Gorges or canyons: During the river erosion, down cutting of its cannel gives rise to a deep narrow valley with
vertical or steep walls. Such a valley is termed as a gorge or canyons.
e. Escarpments: These are erosional land forms produces by rivers in regions composed of alternating beds of hard
and soft rocks. During river erosion soft rocks erode much faster than hard rocks, leaving behind steep slopes on
one side and a gentle slope on the other. The steep slope side is known as the escarpment.
Hog’s back: This is a sharp ridge like structure with high angle sides on two sides formed by harder rocks in an
inclined series of beds.
Mesa and butte: In regions of horizontal strata in which isolated portions of land is capped by a hard, erosion-
resistant bed, the erosional landforms produced will have an isolated flat-topped land area with seep sides,
commonly known as mesa. Isolated masses without flat tops are called buttes.
Transportation: A river is a most powerful agent of transportation. All the material being transported by a
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

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).

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

2. Catchment The area from which water drains into a particular drainage basin. Tributary A river which joins a larger river. Confluence The point at which two rivers join. Watershed The boundary dividing one drainage basin from another- a ridge of high land. What is a drainage basin? Source The upland area where the river begins. Mouth Where the river flows into the sea, or sometimes a lake.
4. The Long Profile of a River Changes in the river as it goes downstream from source to mouth.
5.
6. Valley & Channel Cross-Sections A Upper Course B Middle Course C Lower Course
7. What are the main features of a river? The fastest section of the river, as the channel is widest, with very smooth sides, and the greatest volume of water. The water has increased in speed as the channel widens and becomes smoother. Some boulders cause friction to slow it down a little. Relatively slow moving. Despite areas of fast flowing water, the large amount of material on the river channel bed means that friction will slow the water down. Velocity Deltas; flood plains; levees; meanders; ox-bow lakes Meanders; slip-off slopes; ox-bow lakes Interlocking spurs; waterfalls; V-shaped valley; gorges Features Mainly suspension and solution. Saltation, suspension and solution Traction and saltation Transportation Primarily cuts laterally as it has almost reached base level. The erosive energy of the river is almost totally concentrated on cutting sideways. Much deposition occurs. Continues to cut vertically. But it also begins to cut laterally as it gets closer to base level. Deposition occurs in the slower moving insides of meanders. Primarily vertical erosion, through attrition, abrasion and hydraulic action. Large boulders deposited and eroded in situ. Erosion & Deposition Wide, shallow valley, with large flood plains and meanders. The river channel is wide, deep and smooth sided. v-shaped valley remains with a wider valley floor and the river begins to meander across it. The river channel begins to widen and become deeper. Steep sided v-shaped valley. Thin river channel, deep in places Cross Profile Almost at sea level, very gently sloping towards its mouth Shallow slopes towards the mouth of the river Steeply sloping towards the lower sections of the river Long Profile Lower Course Middle Course Upper Course

9. What processes occur in a river? There are 3 processes taking place in every river. These are: Erosion Transportation Deposition (The wearing away of the land) (The movement of eroded material) (The laying down of eroded material) There are also two other processes that shape the river valley. These are weathering and mass movement.
10.
11. Weathering & Mass Movement. The 3 main types of weathering are show below in the wrong order. Sort the statements out into the right order and copy these onto your sheet. Underneath copy out a definition of mass movement.
12.
13. Erosion Processes Match up the key word with the definition. Abrasion (Corrasion) is when the river is loaded with material in suspension and scours away at the river banks. (Sandpaper effect) Hydraulic Action is the shear force of the river impacting on the sides of the river banks. Corrosion is substances carried in solution such as acids. They dissolve rocks away over long periods of time. Attrition is when bed load collides into each other with the current flow and breaks down into smaller particles.
19. Upper valley characteristics “ V”shape valley, vertical erosion dominant Interlocking spurs Slumping and landslides - very active hill slopes Narrow, shallow channel, low velocity and discharge Large bed load derived from upstream and from valley sides
20. Narrow Channel Lots of tributaries High land so source of river Contour lines close together – steep valley sides Steep river gradient – contours close together Direction of flow shown by lower land No flood plain and V-shaped valley
22. Interlocking spurs A typical upper course V-Shaped valley with interlocking spurs , steep valley sides and active slope processes. The diagram below shows the formation of interlocking spurs.
23. Can you draw an annotated sketch of this valley to show how it is formed?
24. River load in upper course Boulders are large and semi-rounded, due to attrition within the load and abrasion with the stream bed and banks Why are they rounded?
31. Can you put the labels below into the correct place on he diagram?
32.
33. High Force waterfall, R. Tees Waterfalls create a gorge upstream as they recede, This is a steep sided valley with no floodplain.
34. Upper Course of a River Land use: Few settlements, Recreation, Farming, Forestry Steep valley sides Evidence of tributaries Reservoir High land Narrow channel and no floodplain
37. This is a picture of a river in its middle course. Can you recognise and explain the differences between the upper and middle course of a river?
38. Erosion is still an important process. The river is now flowing over flatter land and so the dominant direction of erosion is lateral (from side to side). The river has a greater discharge and so has more energy to transport material. Material that is transported by a river is called its load . Deposition is also an important process and occurs when the velocity of the river decreases or if the discharge falls due to a dry spell of weather. Processes operating in the middle course of a river
39.
40. A meander = a bend in a river Can you match up the characteristics below? There is little frictional drag from the bed and bank at this point and so the river can flow at this speed. Slowest flow Maximum depth of the channel. (Note the asymmetrical cross-profile) Fastest flow Because of the gentle slope, there is a lot of frictional drag and so therefore the river flows at this speed River cliff Formed on the outside bend of the meander due to erosion. Slip off slope A gently sloping area of land on the inside of a meander Deep water
42. Floodplain Deposits on the inner meander bend where there is low energy Erosion on the outer bend where there is faster flow. It creates a river cliff Slip-Off Slope Direction of meander migration
43. Can you match up the labels to the correct place on the diagram?
47. More gentle sloping valley sides Evidence of meanders Land use changes – more urban areas. Small floodplain begins to develop on either side of the river,
48. The Lower Course of a River Learning Objectives: To be able to describe and explain the formation of a flood plain, levees, delta and estuary.
53. This is a cross section of a floodplain. Can you draw a simple sketch of the diagram and the labels below and then annotate it to explain how it is formed? How a floodplain is formed leve é s clays and silts sands

56. Estuaries There are no large deltas around the coasts of the UK, instead the tidal mouth of a UK river is typically characterised with an estuary. Estuaries are wide river valleys flooded daily by the tide. At low tide, large expanses of mud and sandflats are exposed which are mostly composed of material deposited by the river, e.g Thames, Humber, Severn. Thames Estuary
