Abstract
Ground water plays an important role in the overall development of any area. The ground water of India has been decreasing with a significant rate since last decade. Hence, the present scenario of ground water development calls for an urgent step for augmenting ground water resources. The remote sensing and GIS is one of the most advance tools for studying groundwater recharge potential of the particular area of interest.
Hence, keeping ground water development by artificial recharge In mind, the present study has been taken up with objective of investigation to find out the morphometric properties and probable recharge perceptive zones of Mann river basin of Maharashtra state. In the present study; the factors like geology (lithology), soil texture, drainage density, slope and land use land cover have been used along with Digital Elevation Model (DEM) to determine the morphometric properties and to prepare the ground water recharge potential zone map.
The total catchment area of the basin was found out to be 2424.43 sq. km with a perimeter of 345.41 km. The Mann river was found to be a 5th order stream having a total number of 660 streams. The mean stream length of 1st to 5th order streams were 1.3 km, 1.46 km, 6.67 km, 26.52 km and 72.07 km respectively. The stream length ratio of the basin varies from 0.39 to 0.75. The value of bifurcation ratio of the basin varies from 3.04 to 7. The length of overland flow was found to be 0.41 km. The stream frequency and drainage density of the basin was found to be 0.27 number per km2 and 0.82 km/km2 respectively. The texture ratio of the basin was found to be 1.91 and form factor was found to be 0.20. The circulatory ratio and elongation ratio of the basin were found to be 0.26 and 0.51 respectively. The total relief of the basin was found to be 400 m and the relief ratio was found to be 3.64. The ruggedness number of the basin was found to be 0.328.
The final ground water recharge potential map was prepared by overlaying five thematic maps namely, geology, slope, LULC, drainage density and soil map using weighted index method. The map was divided into four categories i.e. low, moderate, high and very high potential zones. The area under low groundwater recharge potential is found to be nearly 103.8774 sq. km. The area under moderate groundwater recharge potential was found to be 1855.96 sq. km. and under high recharge potential was 540.871 sq. km. The area under very high recharge potential zone was found to be only 15.59 sq. km.
Description
The morphometric analysis and prioritization of ground water recharge potential zone of Mann river basin of Buldhana, Akola and Washim distric was done using remote sensing and GIS methods. The thematic maps prepared and used for this purpose were soil texture map, LULC map, geology map, drainage density map and slope map.
