AB  - For the purpose of work on hydraulic models at the laboratory of the “Jaroslav Černi” Institute for Development of Water Resources, a water level meter based on a buoyant force has been developed. This paper presents the specifications and characteristics of level meter, with particular focus on its linearity, dynamic characteristics and usage on hydraulic models. Its relatively simple construction and flexibility allow the user to perform the measurements with high precision.

AB  - Wall deflection in supercritical flow induces standing waves which significantly influence the flow field close to the wall. This paper analyses the flow in the converging stepped spillway, using two scale-models with different step heights and convergence angles. Results show that the height and the width of the standing wave increase with the increase of the convergence angle. Air concentration decreases while the air-water mixture velocity and residual energy head increase in the vicinity of the converging wall and gradually attain the values for the undisturbed flow outside the standing wave. Compared to the prismatic chutes of equal upstream width, converging spillways are less efficient energy dissipators. Equations for predicting the maximum flow depth and the width-averaged residual energy are proposed.

AB  - 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.

AB  - The stilling basin is one of the most frequently used energy dissipation structures due to highly-efficient energy dissipation of the main stream through the secondary turbulent flow in the hydraulic jump roller formed within the stilling basin. An important characteristic of this type of flow is pulsating pressure, which is especially pronounced on the bottom concrete slabs, side walls, and other concrete components of the stilling basin. Hydrodynamic loads on the bottom and side walls of the stilling basin are assessed in the paper, based on pressure measurements at selected points on the physical model. Measurements were made at a large number of test points, such that a reliable distribution of hydrodynamic loading was obtained under different flow conditions.

AB  - The design of the Beni Slimane Dam (Medea Province, Algeria) was verified by scale model analyses, conducted on two separate scale models: a partial model of labyrinth spillway and a complete model of spillway structures. Aeration of the labyrinth spillway, which was the focus of the study, could be properly assessed only by means of a large scaled model, so a partial model at a scale of 1:15 was used. The initial aeration design was improved on the basis of the model investigations. The spillway discharge coefficients, calculated from measured data, were compared to the values recommended in the literature. This paper describes the potential problems, investigation results and important conclusions, which should be kept in mind when labyrinth spillways are designed.

AB  - The design of the RCC (roller-compacted concrete) Bouzina Dam (Batna Province, Algeria) was verified using a scale model. The length scale of the physical model was 1:40 and the hydraulic parameters were scaled applying the Froude similarity. The tests focused on a standard Creager profiled spillway crest (with five bays), a converging stepped chute and a stilling basin. The main design problem was selecting the optimal shape of the stepped chute side walls. The converging chute generated standing waves, resulting in a significant flow depth increase in the vicinity of the walls. The optimal shape of the side walls was selected through a trial-and-error procedure, ensuring the most favorable flow conditions. Improving the flow conditions in the chute resulted in better flow conditions inside the stilling basin as well, so that the initially proposed energy-dissipation baffle blocks could be removed. Measurements of hydraulic parameters (water levels, depths, velocities, pressures) on the scale model verified the proposed improvements (compared to the original design).
