Simulating Fluvial and Coastal Flooding In a Changing Climate (March 7, 2023) with Zhaoqing Yang of the Pacific Northwest National Laboratory and Distinguished Faculty Fellow at the University of Washington.
Extreme fluvial and coastal flooding in low-lying coastal regions are among the most catastrophic hazards to coastal communities. Flooding risk can be exacerbated by the non-linear interaction of high tide, extreme stream flow, storm surge, as well as rising sea level (the result of global warming). Resolving these essential processes requires high-fidelity models that can accurately simulate the riverine hydrology and coastal hydrodynamics in a changing climate.
In this presentation, Zhaoqing Yang of the Pacific Northwest National Laboratory and Distinguished Faculty Fellow at the University of Washington, provides an overview of the development of high-resolution hydrologic model (DHSVM) and coastal storm surge model (FVCOM) for the Delaware River Basin to understand the key flooding processes and the nonlinear interaction of river flow, tides, and storm surge during hurricane events.
