ABSTRACT

 

Water is most important resource for domestic, agriculture and industrial purposes. The main aim of this study is evaluation of ground water potential zones for Hosur Union, Krishanagri District, Tamilnadu. For evaluation, GIS and Remote Sensing Technology contributes on efficient and effective result oriented methods for studying the occurrence and movement of ground water resources. Integration of various thematic layers which influencing the ground water such as slope, geology, lineament density, soil, geomorphology, land use and drainage density 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 occurrence and movement of ground water potential zones in the study area.

 

Keywords : Groundwater potential, Thematic maps, Groundwater suitability index, Remote Sensing, Geographical Information System (GIS)
