Water resource management

Abstract

Water resource management (WRM) is the process of planning, developing and managing water resources across all users in terms of both water quantity and water quality. Integrated water resource management (IWRM), on the other hand, is the coordinated approach of the above processes of not only water, but integrated with land and other related resources. One of the main goals of both WRM and IWRM is to ensure global water security through building capacity, adaptability and resilience in future planning and management of water resources. The Soil and Water Assessment Tool (SWAT) is a continuous-time, semidistributed and process-based river basin scale model to evaluate the impact of management options on water resources, sediment and agricultural chemical yields in ungauged basins. One of the main objectives of the development of SWAT was to evaluate different management options on the hydrology of a basin.
