Discussion of 'Inception Point Relationship for Flat-Sloped Stepped Spillways' by Sherry L. Hunt and Kem C. Kadavy

摘要

The authors presented an interesting contribution to the topic of stepped spillways on moderate slopes. Their work serves as a reminder that the flow properties on moderate-slope stepped spillways, including embankment stepped spillways, may differ from those observed on steep stepped spillways. The authors compared new physical data in terms of the location L_i of the inception point of free-surface aeration with a correlation originally developed for steep stepped spillways [Eq. (1), Chanson (1994)] and a newer correlation Eq.
