Recent severe storms on the U.S. Gulf coast have demonstrated the challenges presented by compound flooding, such as the interactions between rainfall runoff and storm surge. Historically, many studies have neglected these nonlinear interactions, but we propose to use a discontinuous Galerkin shallow water equation sol...

This study introduces a new unstructured computational mesh for hydrodynamic simulations of the Oslofjord. The mesh was created with global bathymetry and shoreline data, using OceanMesh2D. It contains 70,410 nodes, with a resolution at the coastline of 50 meters. We use the new mesh to create an ADCIRC model of the fj...

This paper presents porting of a discontinuous Galerkin shallow water equation model (DG-SWEM version 3.0.2), a discontinuous Galerkin solver for hurricane storm surge, to NVIDIA graphics processing units (GPUs) using OpenACC and unified memory.

This work explores a proof-of-concept application of Deep Operator Networks (DeepONets) as a surrogate for the Simulating WAves Nearshore (SWAN) numerical wave model, and demonstrates consistently high accuracy in predicting the significant wave height and the x- and y- components of the radiation stress gradient.
