Title: Undular bore propagating on a rough invert at Fr = 1.2
Description:
Undular bore on rough screens at Froude no. 1.2. Generation of the surge after gate closure and transformation of a breaking surge on the downstream smooth invert into an undular surge above the rough screens [1]. Duration: 12 s, Q= 58.3 l/s, do = 141.2 mm, So = 0, Rough screens, Gate opening after closure: 95 mm. Credits: References: [1] Chanson, Hubert (2008). Turbulence in Positive Surges and Tidal Bores.
