Since human appeared, the amount of sediments carried by rivers has increased dramatically
Most rivers have eroded and Deposited sediment.

Sediments.
The force that is responsible for moving sediments in a river is the current.
From rocks in rivers and lakes and when the rocks break up over time the sediments inside the rocks go into the rivers and lakes and overtime into the water supply.
The process that carries sediments into rivers is called erosion. Erosion occurs when weathering and other factors break down rocks and soil, which are then transported by water, wind, or ice and deposited into rivers.
Rivers can change the landscape through erosion, transportation of sediments, and deposition. Over time, rivers can carve out valleys, create deltas, and form floodplains. Their continuous movement of water and sediments shapes the land around them.
Rock sediments are deposited at the bottom of a body of water, such as a river or lake. When the flow of water changes direction, the sediment has different momentum, so it does not change direction as fast, and it will collide with the river bank and then settle. Another way is when a river widens or enters a lake, the flow rate decreases, so the particles fall to the bottom. This can also be seen at a delta region when a river meets a gulf or ocean. The Mississippi Delta region in Louisiana the Gulf of Mexico is a good example of this.
It has remained unchanged for most of the time. It is only in recent years that the diversion of water from rivers has changed river flows. In general the flow has reduced so that sedimentation happens further upstream.
