Summary:Bars are important features in stream channel processes as they determine the flow and transport pattern. Many experimental works and field studies have been carried out which provides more information on this phenomenon. Several formulae are theoretically and empirically proposed for the bar height determination. Based on these considerations, a new relationship was developed which has considered two major groups of parameters namely, hydraulic characteristics and sediment characteristics. Establishment of the independent variables was carried out using dimensional analysis approach.
