Marker 16Bancels (crop terraces) and small constructions make it possible to slow down rain runoff and channel it. Here, the stream has a very jagged long profile. The violent autumn storms sorely test these structures, making regular maintenance a necessity. In 2012, very heavy rainfall swept away the bancels and the tapped springs that gave Le Passet gully its shape, creating the current configuration of natural and largely out-of-control gully erosion.
