Title: Morphometric Analysis of Tons basin, Rewa District, Madhya Pradesh, based on watershed approach
Abstract: In the present paper, an attempt has been made to study the morphometric characteristics of subwatersheds in part of Tons basin, which itself is part of the mega Ganga basin in Satna district, Madhya Pradesh. For the purpose of drainage basin analysis, the study area is divided into six subwatershed units. A drainage map of the study area has been prepared with the help of Ilwis 3.4 software. The stream numbers, orders, lengths and other morphometric parameters like bifurcation ratio, drainage density, stream frequency, shape parameters etc. were measured. The low values of bifurcation ratio (mean value of 3.6) and drainage density (mean value of 0.71) suggest that the area has not been much affected by structural disturbances. The sinuosity index value ranges between 1.25 to 1.8, with a mean of 1.5, indicating that the streams are deflected from their straight path and follow somewhat transitional course. Calculation of shape parameters show that the basin is elongated. Watershed wise groundwater level dynamics for the years 2006, 2007, 2008 and 2009 has also been summarised. On this basis, the greater depths of water levels values can be related with low values of stream frequency and infiltration number. The drainage basin study suggests that most of the rocks in the area are of quite permeable nature and there are good chances of infiltration.
