Abstract: The design thought of groundwater modeling information system software(CCRI-GWMIS1.0) was introduced.The software run on the Chinese Windows95,it has the preprocess functions such as data input,automatic generating triangle mesh,Kriging interpretation and so on.It is a simulation system for modeling 2-D confined aquifer,3-D confined aquifer,2-D phreatic aquifer and 3-D phreatic aquifer groundwater flow with finite element method.And it has the postprocess function such as plotting.It has friendly interface and can be operated easy.
