Tamil Nadu, using Remote sensing and GIS techniques

Abstract- Groundwater is one of the important natural resources which support the human health, economic development and ecological diversity. The main aim of this study is evaluation of ground water potential zones for Coimbatore District, Tamil Nadu. Remote sensing and GIS Technology contributes on efficient and effective result oriented methods for studying the occurrence and movement of ground water resources. Integration of various thematic layers influencing the ground water such as, geology, lineament density, geomorphology, drainage and land use have been used to classify the ground water potential zones. Based on this concept, weightage and ranking scores were assigned to each thematic layer with respect of influencing rate of water percolation. Finally weightage, multiplied by ranking and computed all the multiply values for quick assessment of ground water potential zones in the study area
