The area of a river that will most likely contain the most sediment is the riverbed and the banks, particularly at points where the water flow slows down, such as in pools or bends. Sediment tends to accumulate in these regions due to decreased water velocity, allowing particles to settle. Additionally, the river's mouth, where it meets a larger body of water, often has high sediment deposits due to the influx of sediment carried downstream.
Sediment will settle when the river current carrying it along reaches an area of calmness. This may result in sandbars or muddy river banks. It is also likely to settle when carried out to sea and it contributes to the ooze on the ocean floor.
An alluvion is the increase in the area of land due to the deposition of sediment from a river.
The area that is covered with sediment when a river repeatedly overflows its banks is known as a floodplain. This flat, low-lying area adjacent to a river is created by the deposition of sediment carried by the floodwaters. Floodplains are vital for agriculture, as the nutrient-rich sediment left behind by floods makes the soil fertile for crops.

Floodplain
It is called a delta.
The components of a river that are composed of sediment and materials from the watershed area are known as the river's load. This load includes various types of sediment such as sand, silt, and clay, as well as organic matter, nutrients, and pollutants that are carried from surrounding land into the river. This material is transported by the river's flow and can influence the river's ecology, chemistry, and physical characteristics. The interaction between the river and its watershed plays a crucial role in shaping the river's health and ecosystem.
The River Tees primarily carries a mix of sediment types, including sand, silt, and clay. The sediment composition varies along its course, with finer materials found in the upper reaches and coarser sediments, like gravel, in the lower sections. The river also transports eroded materials from the surrounding landscape, contributing to its sediment load. In its estuarine area, the river deposits these sediments, creating mudflats and estuarine habitats.
Floodplain
No, an alluvial fan forms when sediment is deposited at the base of a mountain or hill as a river flows out onto a flatter area, such as a valley or plain. This typically occurs when the river loses energy and slows down, causing it to drop its sediment load. While sediment can also be deposited where a river meets an ocean, this process typically creates a delta rather than an alluvial fan.
A floodplain is a flat, low-lying area next to a river that periodically floods, whereas a delta is a landform created at the mouth of a river where the river splits into smaller channels and deposits sediment. Floodplains are inundated by river water during floods while deltas are built by sediment deposition at the river's outlet.
