On flood planes the water erodes away the banks of the river. The Eroded dirt and sediment fall into the river.
Runoff
Sediment enters a river primarily through mass movement processes such as landslides, debris flows, and soil erosion. These events occur when gravity causes rock and soil to shift from higher elevations into river channels. Additionally, heavy rainfall can accelerate erosion on riverbanks, contributing more sediment to the water. This influx of sediment can significantly impact the river's flow, ecology, and sediment transport dynamics.
From another river, from a spring, from rain etc
The three ways of river erosion are hydraulic action (force of water on the river banks), abrasion (wearing down of the riverbed by sediment), and attrition (erosion caused by rocks and sediment carried by the river rubbing against each other).
Sediment in a river can move via traction, where particles are pushed or dragged along the riverbed by the flow of water. Saltation involves the bouncing or hopping of smaller sediment particles along the riverbed. Finally, suspension occurs when finer sediment particles are carried within the flowing water column.
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.

the 3 ways are:1) solution2)suspension3)bed load
Fast-moving water actually lifts sand and other, smaller sediment and carries it downstream. Water dissolves some sediment completely. Most large sediment falls to the bottom and moves by rolling and sliding.
Louisiana help the economy in two ways. The two ways are by rivers and region.
They fished in river and the lakes Hope it helped ;)
