Abstract: The Kakodonga river basin covered an area is about 1, 113 km2. The aim of this paper to analyses the temperature and rainfall characteristics that is average temperature, rainfall, rainfall intensity, rainfall variability and rainfall ratio of the Kakodonga river basin. The daily temperature and rainfall data for a period of 30 years is collected, converted and computed to monthly, seasonal and annual basis for eleven rain-gauge stations. The average maximum temperature is 28.50C and minimum temperature is 18.40C of the basin. The average rainfall of the basin is 1766mm and total surface of water resources are 1, 965, 558, 000m3. The average annual recharge of the basin is 327mm. The total ground water resources of the basin have been estimated to be 363, 951, 000m3. In the present paper an attempt to study of rainfall analysis of seasonal, annual and rainfall recharge of the Kakodonga river basin. The data can be used for sustainable management and optimum utilizes the resources for sustainable development and other hydrological studies in future. The present study helpful to estimates the future flood zones and to avoid floods to construct the nalla bunds, small ponds, percolation ponds, stone wall, contour trenching, check dams, plantation and afforestation.
