"The Study of siphon spillway hydraulic by odeling (physical and software).
It should be mentioned that most of these researches were focused on the scouring at the impact of jet from a bucket to the downstream and not a comprehensive study was done on submerged jets and it is rare in siphon spillway. The presentation of a new approach to predict scour whole dimensions using neural network is main object of this paper.
Experimental tests were conducted on a hydraulic model of a siphon spillway. A rectangular flume 1m width, 19m long and 0.8m high at the place of scouring and the place of siphon installation 1.6m high was used.
