  • The AA. use the term impoundments to refer to artificial water bodies regardless of size (reservoirs and ponds). They examine the role of these small impoundments in the sediment budget, at the sub-continental scale. Specifically, they estimate
  • This paper reviews the development of geomorphological knowledge of channel changes below dams in 3 phases : channel dynamics, the role of riparian vegetation, and channel change as the driver of ecological regime or steady-state models should
  • be replaced by models of transient states applied to the reach scale in order to respond to the needs of river managers over decadal timescales.
