DEVELOPING A WATER QUALITY MANAGEMENT MODEL FOR KARUN AND DEZ RIVERS
Afkhami, M.; Shariat, M.; Jaafarzadeh, N.; Ghadiri, H. & Nabizadeh, R.
Abstract
The Karun and Dez rivers basin are the largest rivers basin in Iran which are situated in the south west of
the country. Karun River originates from Zagros mountain ranges and passing through Khuzestan plain,
reaches the Persian Gulf. Several cities lie along its path of them the most important is Ahvaz, the center
of Khuzestan province. To achieve water quality goals in Karun and Dez rivers, a water quality
management model has been developed through the GIS approach and a mathematical water quality
model. In Karun and Dez rivers, water quality has decreased due to heavy pollution loads from Khuzestan
province cities and surrounding areas. In this survey, pollution sources, land use, geographic features and
measured water quality data of the river basin were incorporated into the Arc-view geographic
information system database. With the database, the model calculated management type and cost for each
management project in the river basin. Until now, river management policy for polluted rivers in Iran has
been first of all to get penalties from pollution sources and secondarily, to construct treatment plants for
the pollution sources whose wastewater is released untreated and for which the wastewater quality goal of
the Iranian Department of the Environment is not met. 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.
