Abstract

The concept of Ground Water Management centres around establishment of norms leading to optimization of factors necessary for economic utilization of resource without disturbing the system irrevocably and has been used to encompass all activities included under exploration, estimation and development considered necessary for planning and economic utilization of ground water. It has been found that the State of Kerala experiences severe water scarcity during drought period, flooding during monsoons, saline water intrusion along coastal plain, and various water quality problems like occurrence of fluoride, iron and turbidity in ground water etc for the last several years. The effective management of water resources is to be adopted to overcome these adverse effects and for that Delphi method has been utilized. The water conservation activities urgently required to be adopted to alleviate water scarcity during drought period in Kerala is clearly established. One can assume that various natural, geological, anthropogenic and socio-economic-scientific issues are almost similar in the major river basins of Kerala. In this context, an expert opinion study to arrive at the said parameters affecting the surface and sub-surface water resources of Kerala has been carried out. The application of Delphi method on water management in the Kerala state resulted in a number of important policy suggestions based on the data base generated.

INTRODUCTION

Kerala is one of the smallest states in the Indian union having an area of 38, 863 km2 (1.3% of the total area of India) with distinct hydrogeological set up. Management of ground water involves not only geologic and hydrologic considerations but also economic, legal, political and financial aspects (Todd, 2005). Raj Kumar Singh et al (2007) studied a multi-parameter hazard rating system for evaluating groundwater contamination potential of municipal solid waste dumps and landfills by using Delphi technique.The system was based on source-pathway-receptor model and evaluates the site hazard potential on a relative scale of 0-1000, taking into consideration the full leaching life of the waste disposal site and the selection of the system parameters (parameters fall into three categories; source, pathway and receptor)and their best and worst values are based on literature and consultation with experts. Integrated engineering and landscape architecture approaches to address groundwater declines in the High Plains Aquifer (The High Plains Aquifer, which overlies eight states in the central United States- High Plains Aquifer, which resides under the eight states of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming) documented by David R Steward and Eric A. Bernard (2006) using Delphi and GIS Techniques...
