What role do wetlands play in flood protection?

Wetlands play a crucial role in flood protection primarily by absorbing excess rainfall and storm surges. This natural feature acts as a buffer, effectively slowing down and storing water during heavy rain events or hurricanes. The waterlogged vegetation and the porous soil of wetlands can retain significant amounts of water, preventing it from overwhelming nearby areas and reducing the risk of flooding. This absorption capability helps regulate water flow and protects urban and agricultural landscapes from flood damage.

In contrast, wetlands do not cause flooding or provide flood insurance, as those roles do not align with their natural functions. While wetlands themselves cannot entirely prevent floods, they significantly mitigate the impact of excessive water by acting as natural sponges. Thus, their ability to absorb and store water is vital in managing flood risk in coastal Louisiana and similar regions.
