The document summarizes a research study on sediment dynamics in the Rio Grande de Manati Watershed and how land use influences riverine inputs to coastal ecosystems. The goals are to relate land use to sediment inputs in the river, analyze river contributions to the coast through suspended sediment, and establish relationships between suspended sediment, turbidity, and sunlight attenuation in the coast. Methodologies include generating a land use map using remote sensing, collecting suspended sediment samples at sites along the river and coast, and using satellites to measure the outfall influence on the coast. The study will help understand sediment generation and transport in the watershed to inform management practices that control sediment inputs to coastal zones.

DSD-INT 2015 - Effects of fluvial mud supply on large scale - l. braatDeltares
This document discusses a study investigating the effect of fluvial mud supply on large-scale estuarine morphology. The study uses a 2D morphological model with a bed module for sand-mud mixtures to simulate scenarios with different fluvial mud input concentrations. Results show that higher mud concentrations lead to narrower and shallower estuaries and channels with less dynamics. However, issues were discovered with the model's representation of dry cell erosion over long timescales. Future work is needed to expand the model and obtain more validation from field data.
Seafloordynamics in convection models examines how the presence of continents and properties of the lithosphere influence fluctuations in seafloor spreading rates over time according to mantle convection models. The presence of continents enhances time-dependent behavior of mantle convection by forcing consumption of young seafloor. Strong lithosphere moderates the intensity of spreading rate fluctuations, while time scales of fluctuations may be longer than the time spans of tectonic reconstructions.
Discrepancy between knowing a coastal system and mathematical modelling 11112017Marco Pluijm
1) A groyne was built in the 1990s off the coast of Texel island in the Netherlands to slow coastal erosion. Extensive modeling was done but the actual effects were very different than predicted, with accretion occurring on the opposite side instead of reduced erosion.
2) The discrepancy showed that coastal sediment transport processes are still not fully understood and incorporated into models. Phenomenological approaches based on empirical data were sidelined in favor of mathematical modeling.
3) The author argues that a new proposed mega-nourishment project in the same area as the previous groyne poses risks, as coastal dynamics are too complex to be properly modeled given current limitations. A phenomenological approach based on field data is

This document summarizes research on different coastal nourishment designs using physical and numerical modeling. Physical modeling of a beach nourishment showed higher velocities and sediment concentrations near the nourished area under erosive wave conditions. Numerical modeling reproduced sediment sorting patterns along the beach profile. Physical modeling of shoreface nourishments found that designs with larger volumes were more effective at reducing beach erosion. Conclusions indicate that shoreface nourishments placed higher in the profile reduce wave heights more, while different designs respond variably to erosive versus accretive waves. Further research aims to improve sediment transport modeling for small-scale tests and validate models with field data.

This document discusses a study that used field data and XBeach modeling to analyze washover processes on the Wadden Island of Schiermonnikoog in the Netherlands. The study used XBeach's 1D mode to model wave, tide, and storm surge conditions, and its 2D mode to model sediment transport under different washover geometries. The modeling showed that currents dominate sediment transport during inundation, which is influenced by the pressure gradient between water levels in the North Sea and Wadden Sea. The study also found that small, frequent inundation events are important for long-term sediment transport, and that sediment transport is sensitive to the dimensions of washover openings.

Impacts of Hurricane Sandy on the New Jersey Stockysmith
Hurricane Sandy made landfall near Atlantic City, NJ on October 29, 2012 as a Category 1 hurricane with sustained winds of 80 mph. The storm surge exceeded expectations due to coinciding with a full moon high tide, amplifying water levels by 20% and worsening coastal flooding. Beach profiles before and after the storm showed significant erosion of dunes and sand loss from beaches and nearshore areas. Preliminary estimates found New Jersey lost over 14 million cubic yards of sand due to Hurricane Sandy.

GEO-SPATIAL TECHNOLOGIES IN SHORELINE ANALYSIS, VARIABILITY AND EROSIONIAEME Publication
Analysis of shoreline variability and shoreline erosion-accretion trends is fundamental to a broad range of investigations undertaken by coastal scientists, coastal engineers, and coastal managers. Though strictly defined as the intersection of water and land surfaces, for practical purposes, the dynamic nature of this boundary and its dependence on the temporal and spatial scale at which it is being considered results in the use of a range of shoreline indicators. These proxies are generally one of two types: either a feature that is visibly discernible in coastal imagery (e.g., high-water line [HWL]) or the intersection of a tidal datum with the coastal profile (e.g., mean high water [MHW]). Recently, a third category of shoreline indicator has begun to be reported in the literature, based on the application of image-processing techniques to extract proxy shoreline features from digital coastal images that are not necessarily visible to the human eye.

The ever increasing importance of long waves due to accelerated climate change and the impact on vital functions such as coastal stability and port operations.
This document summarizes research on improving coastal and shelf circulation modeling in the Gulf of Lions region of the Mediterranean Sea. It discusses the need for high resolution models to capture fine scale processes driven by atmospheric forcing. A new high resolution (1.25km) regional model is presented that aims to better represent mixed layer processes and intermittent winds. The impact of atmospheric forcing resolution is analyzed, finding that higher resolution forcing improves the model's ability to reproduce observed sea surface temperature variability on short time scales. Overall, the study emphasizes the importance of using high resolution atmospheric forcing to realistically model complex coastal dynamics.
This document discusses climate change and its impacts on Mediterranean coastal zones. It provides an overview of climate change and global warming, including the greenhouse effect and factors contributing to it like increased greenhouse gas concentrations from human activities. Past trends in climatic variables and sea level are examined. Future projections include continued warming and sea level rise according to IPCC scenarios. The Mediterranean Basin's climate and vulnerability to impacts are then assessed, focusing on effects for coastal systems like flooding, erosion and salinization. Adaptation strategies are recommended to reduce coastal vulnerabilities to climate change in the region.
Making florida flood impact resilient by nature 041216Marco Pluijm
This paper is about which mitigation and protection strategies are seen as viable solutions for solving the challenges Florida is facing in terms of sea level rise, flood control and hurricane impact safety and resilience.
Based on the Resilient by Nature approach, which finds its origin in what can be learned from coastal zones which face similar impact exposures or even worse and suffer less damage or hardly any at all. Translating those capabilities to areas less flood and extreme weather impact resilient, such as large parts of Florida.
Solutions for the affected areas are presented as input towards a safer and much more resilient coastal system for Florida and similar places, with regard to a rapid changing climate, accelerated sea level rise and overall related extreme weather impacts.
In order to prevent the situation that large parts of the built environment of Miami and the Keys will become the new Atlantis, sunken and lost cities.

Wetlands and global climate change: the role of wetland
restoration in a changing world
Kevin L. Erwin
Received: 15 April 2008 / Accepted: 24 September 2008 / Published online: 7 November 2008
� Springer Science+Business Media B.V. 2008
Abstract Global climate change is recognized as a
threat to species survival and the health of natural
systems. Scientists worldwide are looking at the
ecological and hydrological impacts resulting from
climate change. Climate change will make future
efforts to restore and manage wetlands more com-
plex. Wetland systems are vulnerable to changes in
quantity and quality of their water supply, and it is
expected that climate change will have a pronounced
effect on wetlands through alterations in hydrological
regimes with great global variability. Wetland habitat
responses to climate change and the implications for
restoration will be realized differently on a regional
and mega-watershed level, making it important to
recognize that specific restoration and management
plans will require examination by habitat. Flood-
plains, mangroves, seagrasses, saltmarshes, arctic
wetlands, peatlands, freshwater marshes and forests
are very diverse habitats, with different str ...
The document discusses the extent to which the oil and gas industry contributes plastics and microplastics to the marine environment. It analyzes data from the North Sea region, where extensive oil and gas operations occur. The report examines definitions of marine litter, plastics, and microplastics. It investigates microplastic uses in offshore oil and gas operations, particularly in drilling fluids, proppants, and cement. The report also assesses studies by Cefas and others on microplastic contributions from various offshore activities and pathways. It concludes that while the oil and gas industry currently contributes minimally to marine microplastics, further investigation and cooperation is needed to fully understand and address microplastic sources and impacts.
socio-economic impact and its assessment in coastal zoneRaja rajan
This document discusses socio-economic impact assessment in integrated coastal zone management. It describes assessing the vulnerability of coastal areas to various human activities through tools like socio-economic analysis and geographic information systems modeling. Several key human activities that impact coastal areas are described, including residence, fisheries, aquaculture, shipping, tourism, land use, and climate change. The document outlines a four-phase approach to conducting use and conflict analysis to identify suitable sites for coastal activities and inform management.
Climate change is affecting West African countries like Senegal and Sierra Leone. Water resources are being impacted through changes in precipitation patterns, including more frequent/severe floods and droughts. This poses challenges for sectors like agriculture, health, and the economy. The paper analyzes climate trends and their effects in these two countries, and proposes adaptation strategies to increase resilience, such as improving water resources governance and adapting infrastructure to hazards like floods and sea level rise.
Catchment classification: multivariate statistical analyses for physiographic...IJERA Editor
The objective of this study was to determine physiographic similarity, as indicator of hydrologic similarity
between catchments located in the Upper Niger Basin, and to derive the dominant factors controlling each group
singularity. We utilized a dataset of 9 catchments described by 16 physical and climatic properties distributed
across a wide region with strong environmental gradients. Catchments attributes were first standardized before
they underwent an integrated exploratory data analysis composed by Principal Component Analysis (PCA)
followed by Hierarchical Clustering. Results showed a clear distribution into 2 major clusters: a group of
easterly flat catchments and another of westerly hilly catchments. This nomenclature came from the
interpretation of the main factors, topography and longitude, that seem to control the most important variability
between both clusters. In addition, the hilly catchments were designated to be dominated by forest and
ACRISOL soil type, two additional drivers of similarity. The outcome of this study can help understanding
catchment functioning and provide a support for regionalization of hydrological information.
1) Climate change will impact Canada's water resources, but these impacts have not been fully incorporated into water management efforts.
2) To project climate change impacts, water managers need future climate datasets and modeling approaches to represent hydrologic processes.

Blog over de opkomst en teloorgang van de Nederlandse (kust)waterbouw, verdewenen kennis en ervaring, klimaatverandering, onwetendheid, de afwachtende houding van de verantwoordelijke overheid, achterhaald en grotendeels totaal niet onderbouwd kustbeleid, de daarmee onlosmakelijk verbonden risiso’s voor onder andere de waterveiligheid, doorspekt en aangevuld met suggesties hoe de onstane situatie vlot te trekken en de gaten te dichten.
1) Accelerated climate change is impacting coasts through multiple interacting factors like changing weather patterns, wave energy spectra, and sea level rise.
2) A potentially significant threat is the increase in long wave energy, which is difficult to measure and analyze due to limitations in coastal monitoring instruments.
3) To better manage these climate change impacts, coastal resilience strategies need to take a holistic, system-wide approach focusing on the balanced interaction between incoming conditions and natural coastal dynamics, rather than traditional approaches like raising sea defenses.
Resilient by Nature Revisited 26022017Marco Pluijm
The document revisits the Resilient by Nature approach for coastal protection against climate change impacts like flooding and erosion. It evaluates the approach as solid and suitable for transferring to vulnerable coastal areas. It identifies several potential spin-off development opportunities from computational models to survey equipment to innovative marine structures. These could help optimize and operationalize the holistic, natural resilience-based approach. Interested parties are invited to explore opportunities and respond with interest.
The document discusses the differences between the Building with Nature approach and the Resilient by Nature approach to coastal protection. While Building with Nature has been profitable, it essentially just recycles sand and studies and does not provide sustainable solutions. Resilient by Nature learns from coastal systems that are resilient to extreme weather and implements natural systems to improve resilience. It requires more in-depth knowledge and experience with system components than Building with Nature. Customers should be aware of the differences between the approaches to choose effective and sustainable solutions for coastal protection.
This document discusses an innovative approach called "Resilient by Nature" for addressing climate change impacts through nature-based solutions. It analyzes systems that have proven natural resilience to extreme weather, such as barrier islands and mangroves, identifies features that provide resilience, and proposes applying these features in other vulnerable areas through holistic coastal systems rather than isolated projects. Examples of resilient features include Dauphin Island which experiences little damage from hurricanes due to its small landmass, and mangroves which reduce wave impacts. The document advocates learning from natural resilient systems and implementing solutions like resilient breakwaters, eco-polders, and artificial reefs to enhance safety and resilience against accelerating climate impacts.
Planning offshore hubs observations and guidelines 14012017Marco Pluijm
This document discusses the concept of offshore ports and hubs. It notes that while the idea is not new, only one has been successfully built - Yang Shan port in China. It attributes this to existing ports being able to handle cargo volumes up until recent changes reduced shipping lines and increased vessel sizes. This has created an urgent need for ports able to service mega-carriers. However, many ports cannot upgrade, risking their viability without regional solutions like offshore hubs. It analyzes past offshore hub plans and identifies key success factors like treating the hub as an ocean connection rather than standalone terminal. Yang Shan is presented as the prime example, becoming the world's largest container terminal through its regional hub role.
Adding impact safety and natural resilience to vulnerable coasts 05012017Marco Pluijm
Given today’s climate change induced challenges, it’s much more effective to follow a system based holistic approach, instead of continue fighting the elements with dated, engineered components.

Klimaatverandering, droge voeten en het belang van een sterke thuismarkt. En waarom resultaten uit het verleden, ook in de waterbouw, geen garantie geven voor de toekomst. En waarom varen op gegist bestek geen optie is.
De aanleiding voor dit stuk ontstond met name nadat op de televisie de verantwoordelijk minister het app'je. "overstroomik.nl" demonstreerde. Alsof dat een reële optie is. Kennelijk wel. U bent gewaarschuwd. En zo zijn de buitenlandse opdrachtgevers en concurrentie.
Nederland was toch altijd het toonbeeld van droge voeten. Het land dat na 1953 nooit meer zal overstromen. Waaromheen een wereld omvattende export is opgebouwd. Als we de minister moeten geloven, dan kan Nederland het nu al niet meer aan.
In dit kader enige persoonlijke observaties vanuit het buitenland van iemand die z’n leven lang in de waterbouw heeft gewerkt. En dat nog steeds doet. Met misschien een paar suggesties...

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
