Improving the Efficiency of Wave and Surge Models via Adaptive Mesh Resolution

The goal of this project is to improve the efficiencies of the widely-used SWAN+ADCIRC models for hurricane waves and storm surge. This goal will be achieved through the use of adaptive mesh resolution and dynamic redistribution of the computational load across multiple processing cores. The objectives of the research are to (a) optimize the computational workload of storm surge calculations by modifying adaptively the mesh resolution as dictated by storm track and cone of uncertainty, and (b) to do so in a way that does not sacrifice parallel efficiency.
