The aim of the study was to characterize the hydrogeology of the catchments, assess water supplies and water usage and evaluate how resilient groundwater may be to change. Two contrasting sub-catchments of the Kali Gandaki river basin were selected to represent some of the main hydrological, physiographical and socio-economic settings present within the middle hills. Some of the preliminary findings of the study based on the observation there is heavy reliance on spring for water supply in middle hills especially in higher altitudes. Natural disasters like landslide, deforestation etc make the spring water and water sources vulnerable so, presence of community forest reduces the vulnerability.
