Résumé :	For economic reasons, many large spillways discharge into unlined rock channels or into the river bed directly. The acceptability of such designs is based on engineering assessment that the unlined channel is sited in rock judged to be sufficiently resistant to erosion at least for high frequency floods. It is accepted that under larger low frequency floods there may be some erosion and damage to these unlined channels, but the damage must be limited and must not endanger the structural integrity of the dam.
