Model Study of a Roller Compacted Concrete Stepped Spillway

摘要

The authors presented the results of one particular laboratory study. The work is helpful in understanding the various aspects of the hydraulics of stepped channels. The discusser wishes to point out that the paper is however incomplete. It deals with one particular case and it should not be considered as the state of the art in model study of stepped spillways. Several important bibliographic references were not considered (e.g. ESSERY and HORNER 1978, FRIZELL 1992, PEYRAS et al. 1992). Altogether the results, presented by the authors, is within the scatter of numerous existing laboratory investigations.
