Climate change has a direct influence on both hydrology and floodplain vegetation of water courses, which are key players in river morphodynamics. The system response to climate is complex the effects non-linear interactions between alterations water, sediment remain incompletely understood. Which these components becomes dominant shaping channel when drier or wetter? To answer this question, w...

Dynamic conditions occur in the coastal ocean during severe storms. Forecasting these is challenging, and large-scale numerical models require significant computing power. In this paper, we describe a real-time modeling system (DUNEX-RT), developed support of During Nearshore Event experiment (DUNEX) off coast North Carolina, United States America. The model run with wave, current, water level ...

Abstract. In the last decade, DEM-based classifiers based on height above nearest drainage (HAND) have been widely used for rapid flood hazard assessment, demonstrating satisfactory performance inland floods. The main limitation is high sensitivity of HAND to topography, which degrades accuracy these methods in flat coastal regions. addition, are mostly a given return period and generate static...

The many thousands of small tidal inlets (STIs), and their adjacent coastlines, are almost certain to be affected by climate change in multiple ways, due behaviour being closely linked both oceanic terrestrial drivers such as riverflow, sea level, ocean waves, all which projected over the 21 st century. Development risk informed adaptation strategies for these highly utilized inhabited inlet-in...

Rising sea levels and the increased frequency of extreme events put coastal communities at serious risk. In response, shoreline armoring for stabilization has been widespread. However, this solution does not take ecological aspects coasts into account. The “living shoreline” technique includes ecology by incorporating natural habitat features, such as saltmarshes, stabilization. impacts living ...

Dikes are the conventional means of flood defence along rivers and estuaries. However, dikes gradually lead to superelevation waterbodies compared subsiding embanked areas, resulting in a rapidly increasing unstable situation under sea-level rise. Therefore, future management requires new, sustainable strategies that not only minimise risk, but also steer land-level An example is transitional p...

Intense human activities may strongly affect coastal environments threatening natural, societal and economic resources. In order to propose adequate measures preserve marine areas, a thorough understanding of their physical biogeochemical features is required. This study focuses on one such area, Izmir Bay located in the Eastern Mediterranean Sea. highly populated area subject many induced stre...

This is the second of two papers on the 3D numerical modeling of nearshore hydroand morphodynamics. In Part I, the focus was on surf and swash zone hydrodynamics in the cross-shore and longshore directions. Here, we consider nearshore processes with an emphasis on the effects of oceanic forcing and beach characteristics on sediment transport in the crossand longshore directions, as well as on f...

i Numerical modelling of the growth of offshore sand waves Preface This thesis is my final work carried out for the double degree Master of Science programme in Hydraulic Engineering and Water Resources Management at the Delft University of Technology and the National University of Singapore. The study was carried out at Deltares and covers various modelling aspects of the growth of offshore sa...

Climate change (CC) is likely to affect the thousands of bar-built or barrier estuaries (here referred to as Small tidal inlets - STIs) around the world. Any such CC impacts on the stability of STIs, which governs the dynamics of STIs as well as that of the inlet-adjacent coastline, can result in significant socio-economic consequences due to the heavy human utilisation of these systems and the...
