In recent years, geomatics practices have arisen as a potential means for morphometric analysis of earth landscapes. The preparation of a morphometric knowledge base is very important for the decision support system of water resource management. Morphometric constraints are vital for effective natural resource management, soil and water preservation, watersheds, and river network evaluation. These methods offer close real-time and precise evidence linked to diverse geological formations, landforms, and assistances in drainage channel identification, which is transformed by natural forces and from time to time by human actions. Due to increasing anthropogenic activities and land cover, the water regime of the regions is significantly affected particularly base flow and groundwater recharge. There are few studies on morphometric analysis of Western Ghats. However, their analysis extent is not covering the current study portions of the Northern Western Ghats area. The morphometric characteristics emphasizing ecological significance of the study region must still distinguished to comprehend the sustainable development of the natural environment, anthropogenic ecologies. Thus, an effort is made to outline the diverse physical features of the watersheds and their spatial disparities in drainage and morphometric parameters existed are considered to assess hydrogeological and geographical features and recognize the association between them in the region using geomatics techniques. The streams that pose dendritic to a sub-dendritic pattern are of 1st to 4th order. The Drainage density seems to vary from 0.98 to 1.16 km/km2, which shows the drainage possesses a coarse to moderate drainage texture. The study tells that the central sub-basins of the region is having high, the southern part of the region is having moderate and the northern part of the region is having low hydroelectric potential. Henceforth, geomatics techniques are powerful tools for drainage delineation, knowledgebase preparation, and water resources management of the regions.
