Erosion är nednötning och transport av berg, jord eller annat material på grund av mekanisk eller kemisk påverkan. Erosion kan till exempel orsakas av vind, rinnande vatten, vågor, glaciärer, gravitationsrörelser, levande organismer, men även genom massrörelsernas materialtransport nedför sluttningar. Till skillnad från vittring så förutsätter begreppet erosion att det även sker en bortförsel. Erosion är en naturlig process. Den har tillsammans med de tektoniska
been formed by sub-glacial fluvial erosion simultaneous with tunnel valley formation, most probably during the latest deglaciation of the area.

Sub-collection, Silver 5 Oct 2018 Because of this boulder mobilization, GLOF impacts far exceed those of the annual summer monsoon, and GLOFs may dominate fluvial erosion 5 Jun 2018 Fluvial erosion is the mobilization of soil at the soil/water interface by moving water. With respect to noncohesive soils, detachment and 27 Mar 2017 Flume tests on fluvial erosion mechanisms in till-bed channels. Journal: Earth Surface Processes and Landforms. Manuscript ID ESP-16-0186. It is concluded that under conditions similar to those of Hawaii marine erosion can approach fluvial erosion in amount only in very early stages of erosion or on the group is about one-seventh of the fluvial total.

FLUVIAL EROSION: STOCHASTIC MODELING FOR RISK ASSESSMENT plains with fluvial erosion were studied for the prognosis of their development
Produktionsområdet har bildats genom flera överlappande perioder av glacial och fluvial erosion. Morfologiskt är det huvudsakligen bergigt, hydrologi/hydraulik (tex Chezy, Manning m.fl), samt fluvial geomorfologi. som visar sambandet mellan erosion och kritisk flödeshastighet. Brant med aktiv erosion, t.ex.
River incision and lateral erosion are important geomorphologic processes in mountainous areas of Taiwan. During a typhoon or storm event, the increase of
The “fluvial erosion hazard” (FEH) also represents a significant concern in areas where human development and infrastructure, are established in close proximity to natural waterways. In mild cases, this may be seen as the gradual loss of a farm field or the undermining of a fence row when gradual channel migration consumes private land. defined as the erosion and deposition rates along the bed interface. The physics of fluvial erosion and deposition would emphasize the distribution of flow velocities, and the velocity variations near the bed surface as key param-eters.

Flusserosion (fluviatile Erosion), eine lineare Erosionsform, ist die Schaffung von Einschnitten in die Landoberfläche durch die Tätigkeit von Fließgewässern (Bäche, Flüsse).
Waterfalls occur when there are rapid changes in the gradient of the river's cause. They occur where there is a marked difference in geoglogy, where resistant rocks are underlain by softer ones. Erosion. Erosion involves the wearing away of rock and soil found along the river bed and banks.
