Impact basin headwall
WitrynaA cirque (French: ; from the Latin word circus) is an amphitheatre-like valley formed by glacial erosion.Alternative names for this landform are corrie (from Scottish Gaelic: coire, meaning a pot or cauldron) and cwm (Welsh for 'valley'; pronounced ).A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a … WitrynaThe velocity of water conveyed through pipes or conduits often exceeds the capacity of the receiving basin or channel to resist erosion. To prevent scour at these sites, protect the outlet structure and minimize the potential for downstream erosion, a flow transition structure is needed to absorb the initial impact of flow and reduce the speed ...
