Numerical simulation of groundwater based on distributed parameter model

To describe the ground aquifer more exactly and distinctly, a three-dimensional distributed parameter model about the movement of groundwater was presented. The simulative region was divided into grids of a certain density and the model was differentiated from space and time. Then cell iterative method was used to solve the model. Taking Hetao irrigation district in Inner Mongolia region as the research object, the model was tested. It indicates that the simulated result is practical and feasible.
