The Karun River is considered to be the longest Iranian river with 855 km length. The river is divided into two branches, 4 km away from the Arvand River, which is a branch of the Bahmanshir River in the north of Abadan, and another branch of the Namkarun River (the Azodi Channel) that flows into the Arvand River. The intersection of the Karun River and the Arvand River is important. Also, measuring and investigating of hydrodynamic phenomena have a vital role in recognizing and prediction the hydrodynamic changes in the region. Therefore, CTD and hydrographic studies were carried out for the Azodi Channel, which is the intersection of the Karun River and the Arvand River. These studies include measurements of marine phenomena such as tidal observations, water level changes, hydrography, topography, CTD and sedimentation. Studies have shown that floods of the Karun River have caused significant changes in the intersection of the rivers Karun and Arvand. Also, the sediment of the study area is fine-grained, but at the intersection of the rivers Arvand and Karun, it is coarse-grained. Sediment concentration is increased in depth, and the lowest and highest sediment concentrations are related to Karun station and Arvand Karun intersection respectively. Regarding the alignment survey, it was found that the current of the study area is mixed current, but mostly meridian. The flow of the Karun River is one of the parameters affecting the water level. So that if the current of the river is noticeable, it will prevent the tidal wave from spreading into the river.
