Its gradient
The floor of a river valley on either side of a river is called a floodplain. Floodplains are areas that are periodically inundated with water during floods, allowing for rich soil and diverse ecosystems. They play a crucial role in the river's health and surrounding habitats, supporting agriculture and wildlife.

The floodplain is an area of flat land found on either side of a river that usually becomes wider as the river nears its mouth. A low watery formation of land at the mouth of a river is called a delta.
A river that deposits fertile soil on either side of its banks during a flood is called an alluvial river. The floodwaters carry sediments and nutrients, enriching the soil along the riverbanks and making it highly fertile for agriculture.
