Hydraulic performance of a pre-aerated stilling basin: Experimental study. [PDF]
Spillway chutes are critical in dam flood control, particularly in high dams where high water heads and large discharge in narrow canyons amplify the demand for safe discharging. For large unit discharges in spillways, aeration protection is essential to

Hydraulics of flow in gabion stepped spillways, an experimental study [PDF]
In this study, the effect of different hydraulic parameters on the energy loss of flow over gabion stepped spillways are examined using physical models and comparisons are made with the other studies.

Abstract In traditional models only an order one fraction of energy is transferred from the inflaton to radiation through nonperturbative resonance production in preheating immediately after inflation, due to backreaction effects.

To protect the dam body and downstream area, spillways should be built. Because the difference in water level upstream and downstream spillways is usually very big, energy dissipation facilities should be introduced.

Proposing a Discharge Coefficient Equation for Triangular Labyrinth Spillways Based on Laboratory Studies [PDF]
Labyrinth spillways are considered as suitable and economic structures because, firstly, their discharge flow rate, under low hydraulic heads, is high, and secondly, they occupy less space.

Numerical investigation of simultaneous effect of end sills and roughness on flow characteristics in V-shaped stepped spillways [PDF]
The special configuration of V- shape stepped spillways increases energy dissipation and aeration compared to the smooth spillways due to the creation of many vortices near the steps. In this research, the energy dissipation in different types of stepped

Study Effect of Fluctuations of Pressure Factors of Stepped Short-throat Shaft Spillways on Hydraulic Coefficient [PDF]
Stepped spillways discharge more flow through themselves than smooth spillways theoretically. Therefore, understanding the flow behavior of these spillways can lead to better and more efficient use. In addition, the use of vortex breaker.
