Floods can lead to soil conservation by depositing sediment and nutrients onto the land, replenishing soil fertility. The water from floods can also help to distribute soil particles more evenly across the landscape, reducing erosion in some areas. In addition, floods can create wetland habitats which can help to filter and purify water, promoting overall soil health and conservation.
