Idealized modeling of storm surges in large-scale coastal basins
Coastal areas around the world are frequently attacked by various types of storms, threatening human lives and properties. This study aims to understand storm surge processes in large-scale coastal basins, particularly focusing on the influences of geometry, topography and storm characteristics on the water levels along the coast. To this end, an idealised process-based hydrodynamic model is developed. For arbitrary closed or semi-enclosed basins, it solves the linearised three-dimensional shallow water equations, including the Coriolis effect, forced by time- and space-dependent wind and pressure fields. Due to it’s linearity, the model is allowed to analyse the problem in terms of the basin's frequency response (which reflects its resonance properties). The model is fast because it decouples the vertical calculations, which are analytical, from the horizontal calculations, which are carried out using the Finite Element Method (or, in simplified cases, using semi-analytical techniques).
