SURFACE WATER RESOURCE EXPLORATION AND ENHANCEMENT – AN OPINION SURVEY OF SATHIYAR MICRO WATERSHEDS IN SIRUMALAI HILL IN ALANGANALLUR BLOCK, MADURAI, TAMIL NADU.
A watershed is a special entity of the environment and it can be distinguished with slope variations and water catchment. The rainfall runoff water drains through tributaries, stream, river and channel to the particular collecting point which is known as watershed. water resources can be classified as various hydrological units like basin, catchment, sub catchment, watershed, sub watershed and micro watershed according to the area covered by them. It is having a maximum limit of 1000ha or 10 sq km areal extent. This study trie to survey the status of surface water exploration and the measures of enhancement of the surface water in the study area of Sirumalai hill in Alanganallur block, Madurai, Tamil Nadu. The primary data were collected by administering questionnaires among the farmers to know the actual status of availability and usage of surface water in the study area. 80% agricultural land is depending upon surface water for irrigation in the study area of Sirumalai Hill environs of Sathiyar reservoir catchment and ayacut area. From the year 2011, digging of bore well and open well are completely banned by the government of Tamil Nadu in Sirumalai Hill. This led to the people for using the surface water for their all activities except for drinking purpose. The surface water resources are getting water from the rainfall, melting snow and from aquifer leakage. In this study, the existing source of the surface water, its availability and utilisation of water are investigated through the questionnaires which were administered to the farmer community of local study area. This survey revealed the major challenges of water scarcity due improper maintenance of drainage system which will affect the storage of surface water and ground water level in future and the potential to support needed for the farmers through watershed management of the Sathiyar River and Sathiyar reservoir.
