Model analysis of the climate change impact on the water balance of groundwater intake in the river valley

Abstract

The results of groundwater intake simulation for Sudogodsky groundwater field under present and forecast climatic conditions for the next 25 years, which reflect the observed changes in meteorological characteristics, are considered. Comparison of the pumped water sources, obtained by simulation, showed that the predicted climate changes will lead to increasing of the reduced groundwater discharge to the river and to decreasing of the induced stream infiltration. Expected climatic changes cause a slight increase in the stream depletion under the influence of groundwater pumping, which will not have negative consequences, as it is compensated by an increase in the transit river flow. The research results reflect the scale of the observed and expected climate changes impact on the pumped water sources for river valley groundwater fields at the center of the European part of Russia.
