Erosion phenomena

Erosion is a natural process that is useful for the hydrogeomorphological functioning of rivers and their ecological dynamics. Erosion makes it possible to feed the river with solid material and is a key factor in the renewal of certain riparian habitats. In areas where land pressure is high, however, it is often necessary to block this erosion and control the lateral mobility of rivers to protect human interests. Indeed, when man-made infrastructures are present on the banks (bridges, roads, buildings, dykes, etc), it is necessary to protect these from erosion to ensure their longevity. For this, bank protection systems must be set up.
