sand bars
Sand bars are located in rivers.
Horse seining
Erosion of the river banks altering the course; deposition of gravel, sand and mud in calmer stretches; obstructing of the river mouth with sand-bars forming in the estuary and inshore.
A 'bar' in a river refers to an accumulation of loose sand or shingle deposited out of the river where the river flow slackens for some reason. During the year the shape of the bed of a large river alters as the flow of water in the river changes with the seasons and this causes the river to pick up and drop sediment from its bed and this has the effect of causing the mounds of sand to move. This movement of a bar of sand with time is called 'migrating'.

I have several sentences for you.The mouth of the river is wider than the rest of the river is.The water at the mouth of the river was filled with silt and sand.There were many sand bars at the mouth of the river.
Sand bars are caused by the deposition of sand along a shoreline where waves and currents slow down and drop sediments. They can form at the mouths of rivers, along coastlines, or offshore in the ocean. Sand bars can change in shape and size due to wave action, tides, and storms.
In the ocean. its a bar of sand in the ocean created by waves in the ocean.
Downstream, with the lighter material travelling the furthest, even reaching the sea. Heavier material may be dropped sooner, forming bars of gravel or sand along the course of the river.
Bars: Accumulations of sediment that form along the river's edges, typically made up of sand and gravel. Braided channels: Multiple shallow, interconnected channels separated by sand and gravel bars, often forming in areas with high sediment load. Point bars: Accumulations of sediment on the inner curve of a meander, formed by the slower flow and deposition of sediment on the inside of the bend.
