On the basis of summarizing the numerical simulation of groundwater systematically and combining Jinan fissure-karst water system

a two-dimensional unsteady flow model is established by using the finite difference method and the finite volume method. And then the dynamic changes of groundwater in the spring field is asseseed. Some conclusions are drawn so as to provide efficient analysis method for the evaluation and management of groundwater resources of the Jinan spring field; and provide significant reference for the evaluation of scientific management of local groundwater resources.
