Morphometric Analysis of Tengli Micro-Watershed using Remote Sensing and GIS

The study was conducted in Tengli micro-watershed and was delineated on the Arc GIS platform. The study ar e is falling under the Survey of India toposheet of E4 3R3 and E43R4 (1:50,000). The drainage pattern of the study area is dendritic with stream order III and lower streams or der dominated in the Tengli watershed. The bifurcat ion ratio (Rb) was 2.75 which show that on undistorted geologic structur e (Basalt and lime stone complex). The circulatory r atio (Rc) (1.05), Compactness Co-efficient (C c) (1.08) and Farm factor Rf (0.86) value indicates watershed was more circular in shape, less elongated with higher peak flows for shorter duratio n precipitation with high intensity. The drainage de nsity (1.64 km km ) and stream frequency (1.41 No.km ) indicates the watershed is having impermeable sub rface material and sparse vegetation. Estimated value of relief (H) was 32 m, b ased on which relief ratio (S') and Stream slope (S) were found to be 0.011 and 5.23 m km respectively. This is an indication of possibly mo derate soil erosion.
