Demarcation of Groundwater Potential Zones Using Remote Sensing, GIS and MIF Techniques in Theni District, Tamil Nadu

- In the groundwater research, favourable groundwater potential zones are identified using integrated remote sensing (RS) and geological information system (GIS) by any researchers all over the World. The present study was carried out to assess the groundwater potential zones using remote sensing and geological information system and Multi Influencing Factor (MIF). The information such as geology map, geomorphology, landuse / landcover map, soil map, slope map, lineament density map were generated and converted to the raster data base using ArcGIS. Multi influencing factor (MIF) is used for distribute fixed score and weight of the features. Finally, all the individual thematic layers are weighted mathematically and generated to the groundwater potential zones. Based on the interpretation, the study area Theni district is classified into four potential categories, viz. , very poor, poor, good and very good. The information can provide the better ideas to planning and management in the study area.
