Title : Study of groundwater potentiality in rainfed plateau of Chhattisgarh using remote sensing and GIS

Abstract :

The present investigation on ground water potential tracks through remote sensing and GIS techniques was carried out for geo-spatial multi-criteria approach. Due to uneven rainfall trend increases demand of below ground water in southern Chhattisgarh, this is urgently needed for sustainable resources of ground water. The dendritic to parallel drainage pattern of area shows showing branches of tree networks and low homogeneity and uniformity. The maximum irregular to moderate irregular surface mainly indicates the occurrence of groundwater. The maximum loss of runoff water does not permit infiltration to recharge zones under groundwater. Slope having 1-3% exhibits mainly flat to gentle considered a ‘good’ category for the groundwater occurrence owing to more favourable to capacity of infiltration of surface factor regarding long term retention of runoff water which indicates low potential for development of groundwater. The area posses 31% cultivated land, 15% concrete, barren scrub and forest scrub covers 12% each with 11% of moderately dense forest providing huge chance of extraction of groundwater round the year (except 2-3 months) in this rainfed region. Area with very high, moderate, poor and very poor groundwater potentiality comprises 2185.43 km2, 519.35 km2, 239.98 km2, 1084.90 km2 and 0.34 km2 which covers 54.23%, 12.89%, 5.95%, 26.92 and 0.01% area in the region, respectively. The surface morphology of the region is characterized mostly by typic haplusterpts (30%) and lithic ustorthents (21%) are major soil types with sensitivity analysis on basis of weightage for all thematic layers exhibits variation from the empirical weights in groundwater potentiality is most response to lithology is a paramount important parameter in assessing groundwater water potentiality and then lineament density, geomorphology, slope and drainage density are considered.
