What happens to a soil during a flood?

During a flood, the soil can become saturated with water, leading to increased moisture levels that can suffocate plant roots by reducing oxygen availability. Floodwaters can also wash away topsoil, nutrients, and organic matter, affecting the soil's fertility and structure. Contaminants from the floodwaters can also be deposited in the soil, impacting its quality and potentially posing risks to human health and the environment.
