Abstract
Water balance and groundwater recharge simulations based on meteorological data with climate trends were made for the South-western part of Moscow artesian basin. Modeling results comparison of mean annual water balance and recharge values for previous (1965-1988) and present (1989-2012) periods allow to estimate their changes due to transient climate conditions. Assessment of groundwater resources climate changes was made on the basis of mean annual groundwater recharge maps for the investigated region for previous and present time periods, which showed their increase of 9% (720 thousands m3/d).

Как показывает анализ многолетних рядов метеорологических характеристик, на всех метеостанциях в юго-западной части Московского артезианского бассейна (МАБ) отчетливо наблюдается увеличение минимальных, средних и максимальных значений температуры воздуха, начиная примерно с середины 80-х годов прошлого века, при этом наблюдаемые тренды увеличения температуры статистически значимы
Summary
Water balance and groundwater recharge simulations based on meteorological data with climate trends were made for the South-western part of Moscow artesian basin. На основе фактических метеорологических данных, характеризующих статистически значимые изменения температуры воздуха и количества осадков на территории юго-западной части Московского артезианского бассейна, проведено моделирование условий формирования водного баланса и инфильтрационного питания подземных вод.
