 Ground Water Resources of Kerala  (Based on GEC 1997 methodology) [Back] [Home]



Ground water being a replenishable resource, its proper and economic development on a sustainable basis requires its realistic assessment.  The National Water Policy too enunciates periodic assessment of ground water resources of India on a scientific basis.  The estimation of the ground water resources of the country gained more importance and to create a national awareness on this issue, the Ministry of Water Resources, Govt. of India issued directives to CGWB and State agencies to furnish the relevant information to the Planning Commission.  The states were asked to form a working group for estimating the resources vide letter no. 18-36/83-GW dated 10.05.1985 from the Additional Secretary, Ministry of Water resources, Govt. of India.  Necessary guidelines were also issued during 1984 and the revised guideline was issued during 1997.  Based on the 1984 methodology the ground water resources were computed during 1989 and 1992 by the Group constituted by Govt. of Kerala earlier.  The same Group with the Secretary (Irrigation).  Govt. of Kerala as the Chairman and the Regional Director, CGWB as Convenor reassessed the ground water resources of the State based on the 1997 methodology. The constitution of the group is given in Table 1.1.

       "The Ground Water Estimation Methodology -1997", is the outcome of the recommendation of a high power committee, which sets the basis for the methodology to be followed by all States/Union Territory for ground water estimation.           

       The data required for the computation were supplied by member agencies and the details of these are discussed in the ensuing chapters on Methodology.  The report has been prepared under the overall guidance of Dr. A.N. Bhowmick, Member (T&TT).  The data collection and the computation of various figures and the preparation of this report has been done under the guidance of Shri M.B.
