Decision Support System for Sustainable Development of a Watersheds Using Remote Sensing and GIS

Prof. S. P. Mehta

Abstract :

The global awareness regarding the over–exploitation of the limited resources, at the expense of causing severe damage to the ecological system and environmental degradation resulted in evolving methodologies for optimum land and water utilization. This necessitates an integrated approach for the optimal development of available resources minimizing hazards to environment. Uniqueness of a watershed in its characteristics as well as problems, the interrelated nature of land and water resources invariably call for the integrated development of the total resources available in a sustainable manner with watershed as a basic hydrological unit for development planning. This leads to the need for a decision support system, which would assist the land user/decision maker for optimum utilization of resources in the watershed. This research focuses on developing a Knowledge based decision support system for agricultural land use development of a small watershed. Essentially, the DSS consists of three main components viz., database, model base and knowledge base. The database contains all the data required for the model base and the physical features of the watershed, which has been compiled from various sources. The model base required for effective watershed development is composed of models for rainfall–runoff, crop–land suitability assessment, soil erosion assessment and crop water requirement. The knowledge base is developed from the results of the model base by utilizing the database. GIS technology, which provides a powerful set of tools for handling spatial and non–spatial data, is employed for the above modeling approaches.
