Development of a tool for managing groundwater resources in semi-arid hard rock regions: application to a rural watershed in South India
2010
Abstract
An operational decision support tool (DST-GW ) designed for the management of groundwater resources in hard rock area under variable agro-climatic conditions has been developed. The tool focuses on the impact of changing cropping pattern, artificial recharge and rainfall conditions on groundwater levels at the scale of small watersheds (10 to about 100 km2 in case well-developed weathering profile).
DST-GW is based on the groundwater balance and the ‘water table fluctuation method’, which are well-adapted methods in hard rock and semiarid contexts.
