Morphometric Characterisation of Atagad Watershed of Uttarakhand

Abstract: The study of the morphometric analysis of the watershed indicates the important factors for estimating the possible groundwater areas, controlling water supplies, conveniently identifying the place for the drainage system's water storage systems, runoff and geographic character. Morphometry is the approximation and mathematical interpretation of the configuration of the surface, shape, dimension of its landforms. For the current research, the morphometric analysis usually consists of dimensional, aerial, and relief aspects. The Remote Sensing and Geographic Information System (GIS) is used to handle and interpret the data present spatially. As mentioned above, the ArcGIS 9.3 has been accustomed to extrapolating various necessary parameters. Digital Elevation Model (DEM) is a 3D terrain conditions visualization. This analysis could also be functional in fields like regional planning, agriculture and forestry. Keeping the above in sight, this study was conducted to properly characterize the Atagad watershed for its morphological properties, in order on the premise of suitable watershed management plan which are often considered by the Government.
