Whenever the river slows down it starts to drop sediment. This usually happens when it meets the sea, unless it meanders slowly across a flood plain in its way.

When their velocity decreases
Rivers deposit their loads in the lowlands of Bangladesh primarily due to the region's topography and hydrology. As rivers flow into the flat, low-lying areas, their velocity decreases, causing the sediment they carry to settle out. Additionally, the monsoon season brings heavy rainfall, increasing sediment load and enhancing deposition. This sediment accumulation creates fertile alluvial plains, which are crucial for agriculture in Bangladesh.
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.
Deltas are formed when rivers deposit sediment at their mouths, typically due to a decrease in flow velocity (such as when the river empties into a larger body of water like the ocean). The sediment builds up over time, creating the characteristic fan-shaped landform. Other factors that can influence delta formation include tides, waves, and varying sediment loads.
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.
