The research aimed at developing a groundwater recharge model from available and reliable data of recharge predictor variables from 1985-2009 for the Sumanpa catchment in the forest-savannah transitional zone. Streamflow data for the Sumanpa River was generated from daily stage data using the rating curve model developed by the researchers at the gauge station. The streamflow data generated was partitioned into its various components, including runoff and recharge by means of the PART and RORA computer programmes respectively. The relationship between the catchment’s groundwater recharge and its predictor variables were determined by means of a scatter plot, using R statistical package, and their strengths quantified using the Pearson Correlation Test. The test indicated a strong positive correlation between recharge, rainfall and runoff and a strong negative correlation with actual evapotranspiration. Based on these a lumped conceptual deterministic groundwater recharge model was developed for the Sumanpa catchment using the multiple regression analysis.
