## Adaptive Finite Element Method for Analysis of Pollutant Dispersion in Shallow WaterSomboon Otarawanna,Pramote Dechaumphai

• 摘要: 介绍浅水中污染物扩散分析中的有限元法．分析包括两个部分： 1） 流场速度、水面高度的计算； 2） 根据扩散模型计算污染物浓度场．联合使用了自适应网格技术以期提高解的精度，同时减少计算时间和计算机内存的消耗．通过几个有已知解的实例验证了有限元公式和计算机程序．最后，使用这种联合方法分析泰国Chao Phraya河附近海湾中的污染物扩散．
