Computational modeling is a convenient method of estimating underground water resources for regions with highly developed underground water resources, with a large number of variable production water supply systems. The use of computational modelling requires reliable informa-tion about a target aquifer’s filtering parameters, as well as its boundary conditions, or features of its interaction with the surface. Methods of determination of filtering parameters, including nodal analysis, which is obligatory, are well -developed, but determination of boundary condi-tions has some difficulties. The paper shows that reliable information about features of aquifer-surface interaction can be obtained by interpreting pumping tests.
