CLIMATIC WATER BALANCE AT THE NAGPUR DISTRICT SITUATED IN THE DRY SUBHUMID REGION

Abstract

Water balance at the Nagpur district was computed from the climatic data. The mean annual precipitation and the potential evapotranspiration values were 124.83 cm and 172.08 cm respectively with the total monthly accumlated water deficit of 97.46 cm being partly met through storage charge and precipitation. Other elements of the water balance viz. water deficit, soil moisture recharge, water surplus etc. were worked out. It was observed that the soil moisture charge (40.45 cm) was useful for the crops during Rabi. Climatic conditions with respect to moisture were favourable during kharif and Rabl seasons but essential during summer irrigations.

Keywords: Water balance, Water deficit, Soil moisture recharge, Dry subhumid region.
