Gravel bar in the American River, Washington, United States. A bar in a river is an elevated region of sediment (such as sand or gravel) that has been deposited by the flow. Types of bars include mid-channel bars (also called braid bars and common in braided rivers), point bars (common in meandering rivers), and mouth bars (common in river ...
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 harbor or river bar is a sedimentary deposit formed at a harbor entrance or river mouth by the deposition of freshwater sediment or by the action of waves on the sea floor or on up-current beaches. Where beaches are suitably mobile, or the river's suspended or bed loads are large enough, deposition can build up a sandbar that completely ...
A pair of downtown Athens watering holes were named on Southern Living's list of 'The South's Most Legendary Dive Bars.'
Today, ocean freighters can travel upriver as far as Portland and Vancouver, and barges can reach as far inland as Lewiston, Idaho. [22] The shifting Columbia Bar makes passage between the river and the Pacific Ocean difficult and dangerous, and numerous rapids along the river hinder navigation.

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 ...
