3. IWRM Integrated Water Resources Planning and Management
New Paradigm
Such a new paradigm is encapsulated in the Integrated Water Resources Management (IWRM) concept, which has been defined by GWP as ‘a process which promotes the coordinated development and management of water, land and related resources in order to maximize the resultant economic and social welfare in an equitable manner without compromising the sustainability of vital eco-systems’.

5. River Basin Management Decision Support Systems
DSS: A process and a tool for solving problems that are too complex for humans alone, but usually too qualitative for only computers. Multiple objectives can complicate the task of decision-making, especially when the objectives conflict.
