Abstract—Shoushtar city is a coastal one why includes a big part of the Karun river and has many water uses; so the crevasse canal of the Gar-Gar as an artificial and manmade branch of the Karun, the biggest river in Iran, and in Shoushtar domain is started in place of the setting dam, Band-E-Mizzan, and it devotes 0.1(according to seasonal measurements averaged) of water volume flowing in the Karun route before the setting dam controlled by the 9 setting windows on the dam. Water current as volume of water, transport water and so sediment particles to other places in route of river canal. Widespread currents through width of river canal transport sediments and coastal erosion in coast lines that are influenced by topography and steepness of river canal. In this research after continuous and regular measurements in two warm and cold seasons (winter and spring of 2009) and comparing with the data collected by zonal water and electricity organization, Khuzestan state (for calibration of the measurements), contours of dominant current in the river width and widespread current with measured current spectrum around the setting dam will be drawn, then effective factors in forming dominant currents will be appointed there. The effective factors on destructiveness of currents in coastlines of the river with a meanders in it will be an applied and useful result of this paper.
