A point bar is an area of deposition typically found in meandering rivers. Point bars form on the inside of meander bends in meandering rivers. As the flow moves around the inside of the bend in the river, the water slows down because of the shallow flow and low shear stresses there reduce the amount of material that can be carried there.
The Columbia Bar is a system of bars and shoals at the mouth of the Columbia River spanning the U.S. states of Oregon and Washington. It is one of the most dangerous bar crossings in the world, earning the nickname Graveyard of the Pacific. The bar is about 3 miles (5 km) wide and 6 miles (10 km) long. [1]
Bar Initiation: The braid bar will form following a series of dune amalgamations. As sediments are deposited to form the braid bar, flow in the channel begins to diverge, with the braid bar acting as a wedge. This stage is associated with high flow in the braided river. Bar Growth: Dune amalgamation continues as an accretionary dune front is ...
A point bar is an area of deposition where as a cut bank is an area of erosion. Point bars are formed as the secondary flow of the stream sweeps and rolls sand, gravel and small stones laterally across the floor of the stream and up the shallow sloping floor of the point bar.

Moreover, river mouth bars are important hydrocarbon reservoirs, [14] [15] and have been widely interpreted in the geologic record. [16] [17] Analyses of the hydraulic and sedimentologic conditions of river mouth bar formation, progradation and aggradation, and prediction on their shape, size and spacing are incredibly valuable for reservoir ...
