Abstract:
Drought is a recurring climatic condition which affects large areas on earth. It is defined as a period of abnormally dry weather that is sufficiently prolonged to cause serious hydrologic imbalance in the affected area (Huschke,1959). Areas affected by drought can range from a few hundred square kilometers to thousands of square kilometers.
The most powerful effect of drought is to reduce agricultural production over a wide area. Other adverse impacts are reduction in hydropower generation, shortage of drinkingwater, detoriotion in water quality, loss of aquatic lives, and reduction in recreational facilities. Other adverse economic impacts
