Application of groundwaters and its effect on environment: a case river in Iran

S.M. Mosaddad, M. Ganj

Abstract


There are some water basins in Iran. The Persian Gulf and the Caspian Sea are the best examples. Also there are some rivers in Iran that are originated from them, for example: The Karoon river and Kore river. The The Karoon river is the biggest one in Iran. It passes from Khuzestan state cities. In Shushtaras an aincient city in Khuzestan, this river has a meander through itself and so a setting dam was built in its route. The setting dam named "Bande Mizzan" divides the The Karoon water flowing to another artificial crevasee named "Gar-Gar". The shape and area of the windows on the dam for controlling water currents follow hydraulic and civil engineering concepts. By this, it would be possible to prevent destruction of the coastal zone in Shushtarand coastal erosion has been decreased notably. In fact there are 9 gates as controlling windows on the face of the The Band-e-Mizzan with a scientific engineering view. The hydraulic pattern used in building the dam is followed for other setting dams in Iran. It has been useful to protect coastal zone in cities near rivers and use river water in life and agricultural well. Deby of water flowing through the gates in the dam is calculated and sedimentation has a very small value. Following civil engineering regulations would be useful in building coastal cities and ports like Shushtar In this paper, we model dominant current deby in the meander in rout of the The Karoon river, Shushtar domain
