ABSTRACT

 

In semi arid tropics watershed planning is accomplished for sustainable development. Watershed characterization and prioritization is carried out before taking up the task of development and planning. Morphometric analysis plays significant role in watershed prioritization. In the present study, geomorphometric investigations coupled with geospatial–statistical technique are used to ascertain green growth potential of watershed for environmental management. Massive data requirement and individual biasness. While assigning weights to various geomorphometry parameters affects the watershed prioritization process. Keeping this in view, Weighted Sum Analysis (WSA) method was used in the present study for identifying critical, priority sub-watersheds and potential green growth area in water scarce region of Western Ghats, India. The result illustrated that 72.26% of total area, falls in the moderately to highly potential green growth. The study demonstrates that a watershed can be categorized into spatially distributed green growth potential zones based on the geomophomteric and terrain characteristics and analysing present land use. The outcome of the study may be useful for watershed managers and planners while implementing sustainable land use planning in the region.
