Answer
River discharge refers to the volume of water flowing through a river at a given point over a specific period of time. It is usually measured in cubic meters per second (m³/s) and indicates the river's ability to transport water and sediments.

Deposition occurs when a river slows down, particularly during floods, causing it to drop sediments along its banks. Over time, this buildup of deposited materials forms natural embankments known as levees, which help to contain the river during subsequent high flow events.
