Modeling of groundwater flow is one of the basic means of analysis and prediction of natural processes. The models serve as the basis for a number of follow-up processes, such as risk analysis, determination of protection zones of water resources, design of landfills and repositories of harmful waste. High-quality models lead to a significant increase in the efficiency of follow-up work and to a reduction in the total financial costs in the implementation of hydrogeological work. In the field of groundwater flow modeling, science is currently focusing on the development and testing of its own simulation tool for simulating the flow and transport of solutes in a cracked porous environment, simulation of hydrogeological experiments, implementation of models of selected areas and interpretation of geological data and their transformation.
