How trees can protect against flooding
18. Dec 2024
Trees are real flood protectors: they stabilise soils, slow down the flow of water and reduce the risk of flooding. They therefore make an important contribution to safety, especially in times of climate change.
Trees play a crucial role in flood protection by helping to regulate the water balance in a variety of ways. Their crowns intercept rainwater and slow its infiltration into the ground, reducing the risk of flash floods. The roots stabilise the soil and prevent erosion, which reduces the silting up of rivers and maintains their capacity. Trees also act as natural barriers that slow down the flow of water and counteract flooding. These natural mechanisms are particularly important in times of climate change, as they help to minimise the risks of flood events
