WebFeb 6, 2024 · What is channel bar geology? Channel bars in alluvial rivers are integral structures in the river channels [1]. The emergence of bars in the river channel is always connected to high water flows which are characterized by high transporting potential. Not without a significance is the geological aspect of the river valleys. WebWhen this mid-channel bar is deposited at the mouth of a river, the flow is routed around it. This results in additional deposition on the upstream end of the mouth-bar, which splits the river into two distributary channels. A good example of the result of this process is the Wax Lake Delta in Louisiana. ... Sedimentary Geology, 120 (1998) pp ...
