Most rivers have eroded and Deposited sediment.

Yes. A slower current cannot carry as much sediment or particles as large as a faster current.

When rivers slow down, they deposit sediment in a process known as sedimentation or deposition. This happens when the velocity of the water decreases, causing it to lose its capacity to carry the sediment, which then settles on the riverbed or banks.
A delta is a deposit of soil that collects at the mouth of rivers. Deltas form when sediment-rich water flows into slower-moving or standing water, causing the sediment to settle and accumulate over time. Deltas are typically shaped like a triangle or fan, with multiple distributaries carrying sediment into the receiving body of water.
River deltas are formed by the deposit of river silt at the mouths of rivers.
The two primary sources of sediment for beaches are rivers and coastal erosion. Rivers transport sediments from the land and deposit them along the coast, while coastal erosion breaks down rocks and cliffs along the shoreline, contributing sediment to the beach.
