Tides and Storm Surge in the Indian Ocean and the South China Sea
Abstract
The goal of the project is to develop a comprehensive high resolution model of barotropic tides and wind driven surge, circulation and wind waves in the Bay of Bengal and the South China and Java Seas. We will develop a single unstructured grid model of this complex region that provides very high resolution of critical geographic and topographic features such as islands, straits, passes, shelves, shelf breaks, continental slopes, submarine ridges, critical seamounts, reef systems, and fringing mangrove and other floodplain systems. We will apply the integrally coupled SWAN+ADCIRC non-phase resolving wave and circulation codes in concert with the high resolution unstructured grid model. We will study barotropic tides, intra-annual wind driven currents and the associated eddy structures, particularly on shelves, slopes, and ridges, tropical storm driven events, and the interaction of these processes. We propose to study dissipation mechanisms for barotropic tides and wind driven currents within this system and quantify shelf dissipation, topographically generated tidal internal wave energy sinks, reef dissipation, and fringe mangrove system dissipation. We will study intra-seasonal wind driven circulation and set-up patterns, in particular looking at advectively driven eddy structures on and adjacent to the shelf and other topographic features, taking advantage of the high resolution capabilities of the model. Our goal is to develop a better understanding of the regional tidal and wind/storm driven waves, surge, and current physics. We will quantify model performance by focusing on tides as well as wind driven events, predominantly on shelves and nearshore stations.
