- Piping (engl. Röhrenbildung) ist eine Form der inneren Erosion. Dabei entstehen röhrenartige Kanäle in oder unter eingestauten Dämmen, Deichen oder ähnlichen Bauwerken aus feinkörnigem Erdschüttmaterial (Sand, Schluff, Ton). Das Piping kann zum Versagen, also zum Bruch des Bauwerks führen. (de)
- Internal erosion is the formation of voids within a soil caused by the removal of material by seepage. It is the second most common cause of failure in levees and one of the leading causes of failures in earth dams, responsible for about half of embankment dam failures. Internal erosion occurs when the hydraulic forces exerted by water seeping through the pores and cracks of the material in the dam and/or foundation are sufficient to detach particles and transport them out of the dam structure.Internal erosion is especially dangerous because there may be no external evidence, or only subtle evidence, that it is taking place. Usually a sand boil can be found, but the boil might be hidden under water. A dam may breach within a few hours after evidence of internal erosion becomes obvious. Piping is a related phenomenon and is defined as the progressive development of internal erosion by seepage, appearing downstream as a hole discharging water. Piping is induced by regressive erosion of particles from downstream and along the upstream line towards an outside environment until a continuous pipe is formed. (en)
- Un renard hydraulique est un phénomène d'érosion interne très dangereux qui se produit dans un ouvrage hydraulique de l’aval vers l’amont. C'est la seconde cause de défaillance la plus fréquente pour les digues, et l'une des principales causes de défaillance des barrages de terre, responsable d'environ la moitié des défaillances des barrages en remblai.

- 파이핑(piping)이란 수리구조물(흙댐, 방조제, 등) 하류단에서 동수경사가 한계를 넘으면 흙이 침식되기 시작하여 결국에 상부 구조물의 붕괴를 일으키는 현상이다. 흙이 침식되면서 유로를 따라 공동이 생기면서 유로가 더 짧아지고, 동수경사가 점점 더 커진다. 유선망은 수리구조물 하류단 유선 출구에서 가장 촘촘하게 그려지고, 이 부근에서 동수경사가 가장 크다. 따라서 파이핑 현상은 이곳부터 일어난다. (ko)
- Piping, onderloopsheid en achterloopsheid zijn termen uit de civiele techniek die aangeven dat er water onder een kade, dijk of ander kunstwerk stroomt als gevolg van een groot waterstandsverschil. Men gebruikt de term 'onderloopsheid' voor stromingen onder kunstwerken, zoals sluizen, 'achterloopsheid' voor stroming langs constructies en 'piping' voor geconcentreerde stroming onder dijken en kades. Gelijkmatige stroming onder deze constructies wordt kwel genoemd. Kwel is over het algemeen niet problematisch voor de constructie, maar levert vaak wel een ontoelaatbaar waterbezwaar op. (nl)
