A flood can wash away important abiotic factors such as soil and rocks that certain biotic factors need for survival.
Degger [83]

Flooding is the term used to characterize the process that occurs when the waters of a river overflow due to rain and occupy the area next to the river, called the river plain. It can have natural or anthropogenic causes and affect vulnerable populations more often.

<h3>What is Biotic and Abiotic?</h3>

The biotic components are all the living things that live in a certain place, while the abiotic components are all the physical, chemical and geological factors of the environment such as water, light, soil, humidity, temperature, nutrients etc.

With this information, we can conclude that A flood can wash away important abiotic factors, such as soil and rocks, that certain biotic factors need to survive, thus flooding affects the ecology of affected regions.
