Hydrodynamic Modeling

Definition

Hydrodynamic modeling is a computational method used to simulate and analyze the movement of water and the forces acting on it, particularly in relation to waves, currents, and other hydrological phenomena. This modeling plays a crucial role in understanding the generation, propagation, and impacts of tsunamis by providing insights into how these massive waves travel across oceans and interact with coastlines, helping to predict potential flooding and damage in coastal areas.
