A main subsystem of the GIMS is the complex simulation model of the regional
water balance that takes into consideration the changeability in surface and river
runoffs, impacts of snow cover, precipitation regime and evapotranspiration.

illustrate schematic structures that are realized in the
item ESWM of GIMS. The model of water quantity is synthesized properly to be a
tool for assessing the dynamic characteristics of hydrologic regime taking into
