Compound coastal flooding considers the joint impacts of marine and hydrologic interactions has recently been identified as an international research priority. Along US West Coast, winter storms often bring high water levels along with energetic waves precipitation. Hydrodynamic models have widely used to estimate flood impacts, including extreme estuarine in compound events (e.g., riverine dis...

Abstract. The Delft3D hydrodynamic and wave model is used to hindcast the storm surge waves that impacted La Rochelle, France, surrounding area (Aytré, Châtelaillon-Plage, Yves, Fouras, Île de Ré) during Xynthia. These models are validated against tide measurements. then estimate footprint of flow depth, speed, unit discharge, momentum flux, significant height, energy total water depth (flow pl...

One of the challenges for model prediction and validation is providing them with data of appropriate spatial and temporal resolution. The maturation and increased application of autonomous underwater vehicles (AUVs) in aquatic environments allows systematic data collection on these model-relevant scales. The goal of this study was to apply a fine-scale circulation and transport model (Delft3D) ...

[1] Climate-change-induced alterations to coral reef ecosystems, in combination with sea level rise, have the potential to significantly alter wave dissipation across reefs, leading to shifts in alongshore sediment transport gradients and alterations to tropical coastlines. We used Delft3D to model schematized profiles of two reef flat widths based on the south Molokai, Hawaii coast. Simulated ...

The validation of numerical models is an important component of modeling to ensure reliability of model outputs under prescribed conditions. In river deltas, robust validation of models is paramount given that models are used to forecast land change and to track water, solid, and solute transport through the deltaic network. We propose using transfer entropy (TE) to validate model results. TE q...

Climate change can strongly influence coral reef ecosystems, affecting species composition, growth rates, and reef morphology, potentially leading to altered wave energy dissipation across reefs. Sea level rise can also alter wave dissipation, which may lead to shifts in alongshore sediment transport gradients, thereby altering erosion and accretion patterns on tropical coastlines. Delft3D was ...

A particle tracking model for the Lingdingyang Bay of Pearl River Estuary (PRE) was established based on Delft3D model. The initialized with remote sensing images to simulate red tide drift-diffusion process in this sea area autumn 2020 and analyze its response tides, winds runoffs. results show that occurred central Bay. drifted south ebb north flood tide. spread northward waters near Humen so...

This study considers the influence of changing sea ice on nearshore sediment transport in central north shore Prince Edward Island, Southern Gulf St. Lawrence. It is widely accepted that climate causing to decrease region. Sea attenuates wave energy thereby reducing transport. The Delft3D hydrodynamic model used simulate waves, currents, and seven concentration scenarios can be differentiated i...
