Title: Decelerating surge against an adverse slope at Fr=2.02

Description: Decelerating surge against an adverse slope at a Froude no. Fr = 2.02. Propagation of the decelerating breaking surge past the ADV unit (x = 5 m). Duration: 33 s, Q= 57.5 l/s, do = 70.1 mm, So = 0.0145, Smooth PVC invert, Gate opening after closure: 90 mm.
Note the slow propagation of the positive surge (bore) which will stop and transform into a stationary hydraulic jump [1].
