Abstract: | Principles of estimation of infiltration groundwater recharge based on modeling the formation of water balance on the land
surface and in the vadose zone are considered. The application of such models for regional discharge evaluation involves zoning
of the territory by a set of meteorological, landscape, geological, soil, and hydrogeological factors. The reliability of
the obtained estimates of water balance components, including infiltration recharge, should be assessed by correlating the
calculated and measured river runoff characteristics for drainage basins within which the water-bearing section in the zone
of active water exchange is completely drained. The application of such approach is illustrated by calculations for southwestern
Moscow Artesian Basin. |
