【Abstract】 New advance of finite element method in numerical modeling of hydrodynamics and water quality is illustrated in this paper.Data preprocessing software has released engineering staff from burdensome data producing and processing and combined use of different kinds of isoparametric element will fit irregular border more accurately.More perfect solution of non_linear and linear equation group will improve accuracy of the solution,shorten the process of iteration and broaden the time span.Xiaohai of Wanning in Hainan Province is selected as application zone and,comparing with actual tested hydrologic data,modeling computation bas been implemented in hydrodynamics,salinity and water quality(degradable object).The results well conform to the actual tested data.更多还原
