 ABSTRACT

Sub-watershed prioritization has gained due importance in the recent time for management of natural resources at a watershed level especially in the perspective of planning and management of watersheds. Analysis of morphometric parameters (linear, areal, relief and shape aspects) is usually the core investigation outline for prioritization of sub-watersheds. The current study makes an effort to prioritize sub-watersheds of Kiknari nala watershed situated in Mandla district of Madhya Pradesh, India by executing morphometric analysis using the techniques of remote sensing and GIS. Different morphometric parameters such as bifurcation ratio (Rb), drainage density (Dd), stream frequency (Fs), texture ratio (Rt), relief ratio (Rh), form factor (Ff), circulatory ratio (Rc) and elongation ratio (Re) for each sub-watershed was calculated using standard formulas and ranks were allocated so as to achieve values of compound parameter.  In the present study, suitable soil and water conservation measures should be adopted primarily for SW – 2 having highest priority rank followed by SW – 1.

Keywords: Morphometric analysis, sub-watershed prioritization, remote sensing, geographic information system, watershed.
