Software DHI Feflow and Processing Modflow in Solving Groundwater Flow Problems for HPP Projects Design and Reconstruction in a Complex Geological and Hydrogeological Environment

An analysis was conducted of the comparison of computational results in the software packages DHI Feflow and Processing Modflow with the analytical solution, and likewise a method of customizing oblique fractures by means of a special application FracTool is proposed, making it possible to perform all necessary actions for the representation of fractures.
