The study area is part of lower Wardha river of Wardha River basin, lies between 200 16’ 00’’ N to 200 35’ 00’’N latitude and 780 14’ 00’’ E to 780 38’ 00’’ E longitude with an area about 781.84 km2 and entire study area has been further divided into sub-watersheds,. It is covered in the Survey of India (SOI) toposheet numbers 55 L/2, L/3, L/6. L/7, L/11 & L/12 on 1:50,000 scale in Yeotmal and Wardha District Maharashtra area, India and forming a part of the hardrock terrain. The drainage network shows dendritic to sub-dendritic pattern and is non-perennial in nature. Poor soil cover, sparse vegetation, erratic rainfall and lack of soil moisture characterize the area for most part of the year. Recurring drought coupled with increase in groundwater exploitation results in decline the groundwater level. Geographical information system (GIS) was used in evaluation of linear, areal and relief aspects of morphometric parameters. After then topology building of the drainage layer in GIS software, from these parameters various drainage characteristics are calculated such as bifurcation ratio, drainage density, stream frequency circulatory ratio, and elongation ratios for basin evolution studies. The understanding of streams in a drainage system constitutes the drainage pattern, which in turn replicates mainly structural/lithologic controls of the underlying rocks. The development of stream segments in the basin area is more or less affected by rainfall. The morphometric parameters are computed using Arc Map 10.2 version GIS software.
