This study by the National Institute of Hydrology deals with the geomorphologic & land use planning for Danda watershed in Tehri Garhwal district of Uttar Pradesh. It attempts to quantify geomorphological characteristics, generation of various thematic data base in GIS format, derivation of land use information using remote sensing digital data, land capability classification and generation of alternate land use plan for the Danda watershed for proper management of natural resources in this mountainous watershed.
Knowledge of land use and hydro-geomorphology is important for planning and management activities concerned with the surface of the earth. The resource managers and planners for agricultural land use need detailed, timely, accurate and reliable data on the extent, location and quality of land and water resources and climate characteristics. The data on landuse potential and the conservation needs can help in planning for uses that will maintain the quality of land. The application of satellite remote sensing for land use surveys and mapping is gaining importance largely because of its ability to provide rapid and reliable data within a given time framework.
Watershed management implies rational utilisation of land and water resources for optimal and sustained production with the minimum hazard to natural resources and environment. It requires collection and analysis of great deal of information on physical relationship of vegetation-soil-water to land management to ensure economic and social progress of a watershed. The success of planning for developmental activities depends on the quality and quantity of information available on both natural and socio-economic resources. Therefore, accurate and reliable data base generation and management is extremely important for devising ways for optimal planning and management of watersheds.
