Les cascades de l'Hérault - long

Violent precipitation and the steep gradient of Mediterranean torrents cause regressive (i.e. upstream) erosion of the valleys through which they flow. This erosion can invert the sense of flow and thus “capture” for the Mediterranean a waterway that had, until then, flowed into the Atlantic. One example is the Hérault with its waterfalls, the capture being located at the falls. The Hérault and the Dauphine brook used to flow via L'Espérou into the Dourbie... River pebbles found around the village by geologists attest to the existence of a waterway in the past.
