Current situation and development trend of numerical simulation of groundwater system

A summary was made on some advances in recent years in numerical simulation of groundwater system at home and aboard,with emphasis on the research ideas,mathematic tools,and software techniques.Current situation about the determination of uncertainty factors for the numerical simulation model of groundwater system and the application of 3S technique and software to numerical simulation was analyzed,and some related problems were put forward.The coupling of multidisciplinary models,study of hydrogeologic parameters,and acquisition of basic information were emphasized.Finally,it is pointed out that the future development of the technique will focus on the following aspects,i.e.the wide application of computer technology,the development of three-dimensional numerical models,and the coupling of different models.
