Morphometric Analysis of Khalri Drainage Basin Using Remote Sensing (RS) and Geographical Information System (GIS)

Remote Sensing (RS) and Geographical Information System (GIS) has an efficient tool in delineation of drainage pattern and ground water potential and its planning. GIS and image processing technique can be employed for the identification of morphological features and analyzing properties of basin. The morphometric parameters of basin can address linear, areal and relief aspects. The present study deals morphometric parameters such as stream order (NU), Stream length (LU) Bifurcation Ratio (Rb) drainage density (Dd) stream frequency (Fs), Elongation ratio (Re), Circulatory ratio (Rc) and farm factor (Rf) etc. The GIS based morphometric analysis of this drainage basin revealed that the Tanda is 4th order drainage basin and drainage pattern mainly in sub-dendritic to dendritic type indicates homogeneity in texture and lack of structural control. Total number streams is 183, in which 144are first order, 52 are second order, 5 are third order and 12 are fourth order streams. The length of stream segment is maximum for first order stream and decrease as the stream order increases. The drainage density (Dd) of the study area is 1.37 km/km2. This study will help the local people to utilize the resources for sustainable development of the basin area.
