Operator Learning for Predicting Bulk Wave Parameters of Spectral Wave Models
Shukai Cai, Sourav Dutta, Mark Loveland +4
The impact of wave-induced forcing on the mean water level and nearshore currents is typically modeled through excess momentum fluxes, also known as radiation stresses, and their s…

A Neural Operator Emulator for Coastal and Riverine Shallow Water Dynamics
Peter Rivera-Casillas, Sourav Dutta, Shukai Cai +7
Coastal regions and river floodplains are particularly vulnerable to the impacts of extreme weather events. Accurate real-time forecasting of hydrodynamic processes in these areas…
