3차원 흐름 모델링시스템(FEMOS)을 이용한 아산만 조류모의

Abstract

A modeling system for three-dimensional flow (FEMOS) has ben developed and applied tosimulate the tidal currents of Asan Bay. The system can consider tidal flats changing with time and uses a finiteelement method that can adapt coastline change effectively. The simulation results for Asan Bay with large tidalflats, shallow water depth and high tidal range showed god agrements with the observed currents of long-termvariations at the medium layer and short-term variations of vertical profiles. Based on the simulated tidalcurents, the horizontal distributions of bottom shear stress were calculated and showed close relation with thechange of bottom topography. The system can be used widely to study coastal circulation in the coastal regionwith complex geography.
