Abstract

Abstract

A finite element method for analysis of pollutant dispersion in shallow water is presented.The analysis is divided into two parts:1) computation of the velo city flow field and water surface elevation,and 2) computation of the pollutant concentr ation field from the dispersion model.The method was combined with an adaptive meshing technique to increase the solution a ccuracy,as well as to reduce the computational time and computer memory.The finite element formulation and the computer programs werev alidated by several examples that have known solutions.In addition,the capability of the combined method was demonstrated by analyzing pollutant dispersion in Chao Phraya River near the gulf of Thailand.
