Watershed prioritization has gained importance in natural resources management, especially in the context of watershed management. Morphometric and land use analysis has been commonly applied to prioritization of watersheds. In the present study, prioritization on the basis of morphometricand land use analysis of watersheds have been performed for the Dudhganga catchment of Kashmir Valley J&K. Various morphometric parameters, namely linear and shape have been determined for each watersheds and assigned ranks on the basis of value/relationship so as to arrive at a compound value for a final ranking of the watershed. Land use/land cover change analysis of the watersheds has been carried out using multi-temporal data of Land sat TM of 1991 and Land sat TM of 2010. The study demonstrates the significant land use changes especially in built up land, agricultural lands, plantation, forest, scrubland, and wastelands from 1991 to 2010. Based on morphometric and land use/land cover analysis, the watersheds have been classified into three categories as high, medium and low in terms of priority for conservation and management of natural resources.
This paper makes an attempt to delineate groundwater potential zones in a catchment by using scientific information of lithology, topography, geophysical characterization and their interrelationship. On the basis of relative contribution of each of thematic layers towards groundwater potential, the weight of each thematic map has been selected. The individual theme weight was multiplied by its respective class weight and then all the raster thematic layers were aggregated in a linear combination equation. Groundwater potential zones map revealed that the plain areas are prospective zones in the catchment and can be helpful in better planning and management of ground resources.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
