Groundwater resource development in Jamui District,Bihar, India: an overview

Because agriculture is the main source of livelihood for the bulk of the population in Jamui District, the importance of developing irrigation facilities in any programme of economic regeneration can hardly be over emphasized. It is, therefore, imperative that groundwater development be considered as an important step to drought mitigation in the Jamui district. The present study was carried out in such a way that technical and economic viability of any groundwater development plan can be thoroughly scrutinized. In this paper the hydrogeological framework of the district was established based on aquifer disposition, orientation of potential fracture systems and their hydraulic characteristics. Considering the aquifer geometry and yield potential of different structures, a blueprint for a groundwater development plan was prepared. An economic analysis of the development plan also was attempted. The analysis yielded results that made it possible to evaluate parameters such as cost–benefit ratio, incremental benefits and internal rate of return used to assess the economic viability of the groundwater development plan.
