GROUND WATER MANAGEMENT STUDIES
Ground Water Resources occur in dynamic state and hence subjected to periodic changes. Ground water Management Studies (GWMS) are essential to update the scenario of ground water occurrence, availability and utilization in term of quality and quantity with reference to the previous studies. The effect of ground water withdrawals and out-flows are directly measurable through water table. Since, the main inputs and outputs frequently change with time, the ground water situation is being periodically reappraised. The development of ground water resource leads to changes in its regime and water quality, therefore planning for further development of the resource is to be done on the basis of findings of the studies, which provide valuable information for reorienting ground water development programme keeping in view the emerging scenarios.
The objectives of the GWMS are as follows:
- To depict the ground water regime in terms of quality and quantity as on the date.
- Ascertaining the factors influencing the ground water scenario.
- Identification of problems and issues pertaining to ground water and provide suitable object oriented strategy for implementation.
- To assess the social and economic aspects of ground water utilization and the role of various agencies, Panchayat Raj, NGOs and VO etc., in ground water development, conservation and management
- To update the existing database on ground water regime.
- To demarcate the ground water worthy and unworthy areas.
- To recommend suitable follow up action/ remedial measures/ administrative and technical measures for the specific problems.
Various themes covered through ground water management studies during 2008-09 were as follows:-
- Demarcation and assessment of artesian aquifers,
- Mapping of flood plain aquifers,

- Conjunctive use of surface and ground water in Irrigation command,
- Optimum utilization of ground water resources,
- Ground Water Resource Assessment,
- Ground Water Management Studies in the Farmers distress areas,
- Over-exploited area,
- Naturally contaminated area,
- Studies for Reclamation of Ravines,
- Mining Hydrogeology,
- Remote sensing studies,
