Subject Geohydrodynamics gives a basic overview of patterns of groundwater flow in the rock environment in both saturated and unsaturated zones. In addition to the problems of porous media flow, attention is paid to hard rock – fracture flow (Cubic Law). Students are acquainted with the hydraulic parameters of aquifer and the methods of their determination in the laboratory and with hydrodynamic field tests. Students are encouraged to practice using analytical calculation equations - calculation of fluxes through the dam, hydraulic systems for dewatering construction pits, etc.
