Abstract. Accurate flood risk assessments and early warning systems are needed to protect prepare people in coastal areas from storms. In order provide this information efficiently on time, computational costs models need be kept as low possible. One way achieve goal is apply subgrid corrections relatively coarse grids. Previously, these have been used full-physics circulation models. paper, for the first we developed linear inertial equations (LIEs) that account bed level friction...
In predicting storm impacts on sandy coasts, possibly with structures, accurate runup and overtopping simulation is an important aspect. Recent investigations (Stockdon et al., 2014; Palmsten Splinter, 2016) show that despite predictions of the morphodynamics dissipative beaches, XBeach model (Roelvink 2009) does not correctly simulate individual contributions set-up, infragravity incident-band swash to wave run-up. this paper we describe improved numerical scheme a different way simulating...
The West African coastal barrier is maintained by significant wave-driven longshore sand transport. This originates from rivers and large deposits. Today, however, much of the fluvial trapped behind river dams and/or interrupted at several locations port jetties. As a result, sandy eroding almost everywhere along its length. aim this study to derive large-scale sediment budget analysis, following consistent approach, for countries: Republic Côte d'Ivoire, Ghana, Togo Benin, pointing out...
Abstract A 38-year hindcast water-level product is developed for the US Southeast Atlantic coastline from entrance of Chesapeake Bay to southeast tip Florida.

Abstract The open-source program Delft Dashboard (DDB) is a graphical user interface designed to quickly create, edit input parameters and visualize model inputs for number of hydrodynamic models, using private or publicly available local global datasets. It includes toolboxes that facilitate the generation spatially varying inputs. These include new schematizations (grids, bathymetry, boundary conditions, etc.), cyclonic wind fields initial tsunami waves. use DDB can have significant...
Coastal flooding affects low-lying communities worldwide and is expected to increase with climate change, especially along reef-lined coasts, where wave-driven particularly prevalent. However, current regional modeling approaches are either insufficient or too computationally expensive accurately assess risks in these complex environments. This study introduces validates an improved efficient physics-based approach compute dynamic on coasts. We coupled a simplified-physics flood model...
The Puget Sound Coastal Storm Modeling System (PS-CoSMoS) is a tool designed to dynamically downscale future climate scenarios (i.e., projected changes in wind and pressure fields temperature) compute regional water levels, waves, compound flooding over large geographic areas (100 s of kilometers) at high spatial resolutions (1 m) pertinent coastal hazard assessments planning. This research focuses on advancing robust computationally efficient approaches resolving the components for complex,...
Abstract. Tropical-cyclone impacts can have devastating effects on the population, infrastructure, and natural habitats. However, predicting these is difficult due to inherent uncertainties in storm track intensity. In addition, computational constraints, both relevant ocean physics meteorological forcing are only partly accounted for. This paper presents a new method, called Tropical Cyclone Forecasting Framework (TC-FF), probabilistically forecast compound flooding induced by tropical...
Abstract. The design of coastal protection measures and the quantification risks at locations affected by tropical cyclones (TCs) are often based solely on analysis historical cyclone tracks. Due to data scarcity random nature TCs, assumption that a hypothetical TC could hit neighboring area with equal likelihood past events can potentially lead over- and/or underestimations extremes associated risks. simulation numerous synthetic tracks (historical) overcome this limitation. In paper, new...

Abstract. Parametric wind profiles are commonly applied in a number of engineering applications for the generation tropical cyclone (TC) and pressure fields. Nevertheless, existing formulations computing fields often lack required accuracy when TC geometry is not known. This may affect computed impacts generated by these winds.
