Regional Water Quality Management for the Karun-Dez River Basin, Iran

To achieve water quality goals in a river basin, a water quality management model has been developed through the GIS approach and a mathematical water quality model. The developed model has been applied to the Karun and Dez Rivers, where water quality has decreased due to heavy pollutant loads from Khuzestan Province Cities and surrounding areas, Pollution sources, land use, geographic features and measured water quality data of the river basin were incorporated into the ArcView geographic information system database, With the database, the management model calculated management type and management cost for each management project in the river basin. Different management projects with a time program were proposed and they were compared with the results of the river quality without any management approach. It became clear that the results based on the management approach were much better than those for the unmanaged condition from the viewpoint of the achievement of water quality goals and cost optimization.
