I think sediment can enter a river through erosion. PLease dont use this anwser i dont think it is right
sediment
River efficiency is how easily a river can move water, sediment and bedload.
sediment
The main parts of a river include a channel, in which the water flows, and a floodplain-a flat region of a valley on either side of the channel. Through the channel and floodplain, water and sediment-material transported by the river, such as sand and silt-are transferred from ridges and mountains to the sea or to a lake. A river starts on hillsides as small channels, or rills. The rills combine to make larger channels or tributaries that eventually come together, forming distinct streams. The largest channels formed by this convergence of tributaries are rivers, and they can carry large quantities of fresh water and sediment across continents.
Clay, sand, silt.
Sediment can enter a river through erosion of the riverbanks, from runoff carrying sediment from surrounding land, through landslides or mudflows, and from human activities such as construction and mining.

Streams erode sediment primarily during times of high flow or flood events when the velocity and volume of water are increased. The force of the water helps carry and transport sediment downstream, causing erosion along the streambed and banks. Wind and ice can also contribute to sediment erosion in streams.
River hydraulics involves flowing water and its impact on the landscape. This includes the hydraulic characteristics of streams and rivers ranging from dam break analysis to sediment movement analysis.
The size of the sediment would decrease further downstream (where there is a greater volume of water) as there is more energy in the flow. Therefore more erosion will occur and the sediment will rub together with other materials i.e other rocks or the river bed (this is called attrition). The sediment will therefore reduce in size but there will be a greater amount of it. (The amount of sediment is called the discharge.)
Rivers, streams or such like that flow into another larger river
Eroded soil can enter water bodies such as rivers, lakes, and streams, where they accumulate and cause sedimentation. This can lead to decreased water quality, habitat degradation, and reduced water flow capacity.
Sediments carried by a river are typically deposited when the river's velocity decreases, such as in areas with gentle slopes, bends, or at the river's mouth where it meets a body of standing water like a lake or ocean. This decrease in velocity results in sediment settling out of the flow and accumulating on the riverbed.
A stream or river that feeds into another river is called a tributary. Tributaries play a crucial role in the overall health and flow of a river system, as they contribute water, nutrients, and sediment to the main river.
