Decomposition and superposition principle used innumerical models of groundwater flow

Although the application of superposition principle to groundwater calculation is very common,it is usually limited to analytical solution.This paper briefly introduces the concept of superposition principle of linear mathematical models,and proposes superposition principle of discrete linear mathematical models,and discusses the problem of its application to groundwater numerical modeling.The decomposition and superposition of groundwater models can simplify the problem to be solved and help un...
