In this hydrological study, analysis and interpretation of hydro-meteorological data in the study area, watershed delineation, catchment geomorphologic characterization , water balance evaluation of 20 watersheds i.e. annual recharge estimation and conceptualization of the enfluent and influent type of streams in the study were identified. From the rainfall data analysis in and around the study area, there are two peak rainfall seasons (rainfall pattern is bimodal in nature). The months July, August and September, April, March, June and May are rainy months. July, August, and September are heavy rainfall months, and the months with small rainfall are March, April and May. The months January, February, October, November and December are dry months with rainfall coefficient less than 0.6. The rainfall coefficient ranges from 0.1 to 3.6, in the months of December and July respectively. The rainfall decreases from the highland to the low lands.
