The sediment is washed into the sea by runoff from the land, especially by rivers and streams. Most of this sediment does not travel very far offshore before settling.
Sediment is typically deposited in bodies of water and low-lying areas during flooding events, when the water flow slows down and sediments carried by the water settle out due to gravity. Sediment can also be deposited gradually over time through erosion and weathering processes.
Sediment is typically deposited in bodies of water and low-lying areas when the energy of the transporting medium (such as water or wind) decreases, causing it to no longer be able to carry the sediment. This can happen during periods of low flow or calm conditions, allowing the sediment to settle out and accumulate.
Yes, when the flow of a river slows the sediment is deposited.
The flow of water slows enough for the silt to be deposited.
Mudflats are formed in areas with low energy coastal environments where sediment-rich water is deposited. When water flow decreases, the sediments settle, forming mudflats. Tides also play a role in shaping mudflats by bringing in more sediment while also eroding and sculpting the mudflat surface.
Deposition
Eroded sediment can end up in various places, such as rivers, lakes, oceans, or coastal areas. Sediment may accumulate at the bottom of these bodies of water, be transported downstream, or be deposited along the coastline. This process plays a crucial role in shaping landforms and ecosystems.

Factors that affect sediment deposition include water velocity, sediment size, and topography. Sediments are typically deposited in areas with low velocity where energy is minimal, resulting in flat features like floodplains or deltas. In areas with high velocity, sediment is less likely to be deposited, leading to features like channels or steep riverbanks.
Baymouth bars typically form at the entrances of coastal bays and estuaries where sediment is deposited by wave action and longshore drift. They create a barrier that partially encloses the bay, often leading to the formation of lagoons or shallow water areas behind the bar. These features can be found in various coastal regions around the world, particularly in areas with strong wave action and ample sediment supply.

Waves transport and deposit sediment in coastal areas through a process called longshore drift, where waves approach the shore at an angle, moving sediment along the coastline. As waves break, they generate a backwash that pulls sediment back into the ocean, while the swash carries it up the beach. This continuous movement reshapes the coastline, depositing sand and other materials in areas like beaches and sandbars. Additionally, variations in wave energy can lead to sediment accumulation or erosion, influencing the coastal landscape over time.
The heaviest sediment will always be deposited first. Which sediment is the heaviest in that flowage can vary widely.
Coastal erosion can lead to the loss of sediment and land in coastal areas, which can impact the formation and stability of bays. As erosion removes sediment from coastal areas, it can contribute to the shallowing of bays or changes in their shape. Additionally, the loss of protective coastal features like dunes or wetlands due to erosion can leave bays more vulnerable to wave action and storm surges.
