Evaluation of Groundwater Potential Zones Using Electrical Resistivity and GIS in Noyyal River Basin, Tamil Nadu

Abstract

The purpose of this study was to identify the groundwater potential zones in Noyyal river basin using GIS and electrical resistivity. River Noyyal was perennial with good flow till early seventies. In recent years, the scene has changed drastically and the river has become practically seasonal and receives copious water during northeast monsoon from September to November. The rest of the years it remains more or less dry. Since the surface water resources in the area are inadequate to meet the local needs it is necessary to explore groundwater resources which has not been done properly. Hence various thematic maps have been used for the preparation of groundwater prospective map by integrating geology, geomorphology, slope, drainage and lineament of the study area. Electrical resistivity survey was conducted at 52 locations by using Schlumberger configuration. From this weathered thickness and depth to basement have been taken and overlaid for identifying groundwater potential sites and finally this result was compared with yield data. The interpretation shows that the entire study area has moderate to good category of groundwater potential.

Identification of Groundwater Potential Zones Using Remote Sensing and GIS Techniques: A Case Study of the Shatt Al-Arab Basin

“…Around the world, different methods have been used in delineating GWPZs such as integration of remote sensing and GIS with resistivity data [77], influence factor (IF) [47,51,66], statistical methods [78,79], groundwater modeling [80], and analytical hierarchy process (AHP) [63,74,81]. These methods have been proven as reliable and effective, and have been used by many researchers.…”

“…Survei keberintangan elektrik turut dilakukan di sekitar kawasan kajian bagi mendapatkan maklumat bawah permukaan. Survei keberintangan elektrik merupakan salah satu kaedah yang boleh digunakan untuk mendapatkan maklumat seperti keadaan ruang lohong, struktur geologi dan air bawah tanah (Arifin et al, 2016;Nazaruddin et al, 2017;Selvarani et al, 2016). Kaedah ini mampu memberikan maklumat bawah permukaan secara cepat, kos yang murah dan merangkumi kawasan yang luas.…”
