Closure to 'Energy Dissipation down a Stepped Spillway with Nonuniform Step Heights' by Stefan Felder and Hubert Chanson

摘要

The writers thank the discussers for their comments. Herein they develop on the dimensional considerations and residual head data. In skimming flows above prototype stepped spillways, two key features are the strong free-surface aeration and air-water flow turbulence (Chanson 2001). In any dimensional analysis, the relevant parameters include the fluid properties and physical constants, the chute geometry and inflow conditions, the air-water flow properties, and the geometry of the steps (Chanson and Gonzalez 2005; Felder and Chanson 2009).
