Scale modeling of Beni Slimane Dam

Abstract

The design of the Beni Slimane Dam (Medea Province, Algeria) has been verified by scale model analyses, conducted on two separate physical models - the partial model of the labyrinth spillway and the complete model of flood evacuation structures. This paper describes the analyses carried out on the complete model, scaled 1:30. The initial design of the chute and stilling basin was optimized on the basis of model testing. Tests carried out on the scale model with a movable bottom (river bed) were very helpful for the design of downstream erosion protection.
