Flooding rivers enrich the areas around them by depositing

Flooding rivers enrich the areas around them by depositing sedimentation of solid material like rocks and minerals, as well as the remains of plants and animals.

Explanation:

Sedimentation is the process of deposition of particles moved to a new location. That moves on the basis of the current of the flood. It can carry like small stones, pebbles, minerals along with them and some plants or animals remain in the soil.

It actually enriches the soil with nutrients since the soil will be drifted away along with the sediments during the flood. This soil can be used for farming and in the case of Flood Plains helps them to grow healthily. In the delta area and river banks, huge amount of sediments will be found. That results in these regions to be the most fertile agricultural region.
