The Dez catchment is in Khuzestan province and belongs to Persian Gulf and Oman Sea catchments. Dez River is one of the main tributaries of Karun River, one of the most important river in Iran, collecting water from a vast area in Lorestan, Isfahan and Khuzestan provinces and transferring them into Karun River.
Dez River has 2 main and some small tributaries. The main tributaries are Ab Bakhtiyary (Ab Zalaki) and Sezar rivers. Bakhtiyary River originated from Bakhtiyary mountains, runs in the east direction and joins Sezar River which is originated from north of Loristan province.
Dez River supplies a major part of the irrigation water demand of Khuzestan province, which is enhanced by the construction of Dez Dam. The river, after the dam, enters Khuzestan plain and Dezful plain and eventually joins Karun River at Band-e-Ghir. The river regime is mainly snowmelt- rainfall.
The objectives of the present hydrological studies are, estimation and determination of monthly and annual discharges, flow duration curve, floods with different return periods at the entrance of the dam reservoir which are essential to performing sedimentation studies and sediment management.
