Computational Investigation of Flow over Gabion Spillways [PDF]
, 2018 A spillway is a hydraulic structure that is used to pass high discharges in flood seasons in a controlled way and also to release surplus water that cannot be safely stored in the reservoir to downstream.

Evaluation of Energy Dissipation and Hydraulic Characteristics of Flow on Simple and Inclined Stepped Spillways using FLUENT Model [PDF]
علوم و مهندسی آبیاری, 2018 Stepped spillways are hydraulic structures which due to the high energy loss of flow have important role in reducing dimensions of stilling basin of downstream of the dams and consequently their economical design.

GEOMETRY OPTIMIZATION OF TRIANGLE LABYRINTH SPILLWAY USING ANFIS MODELS AND GENETIC ALGORITHMS [PDF]
مجله مدل سازی در مهندسی, 2009 Labyrinth spillways were considered as one of the appropriate options to pass PMF discharge where the system had difficulties. In a certain width in similar head these spillways with nonlinear crest can pass greater discharges compare to spillways with ...

Scour due to turbulent wall jets downstream of low-/high-head hydraulic structures
Cogent Engineering, 2016 To overcome over-prediction of the scour depths by existing methods, a mathematical model is developed based on a work transfer theory. This model predicts the equilibrium scour hole’s depth and length due to two-dimensional turbulent wall jets ...

A Study of pressure fluctuation caused by hydraulic jump in stilling basin [PDF]
مهندسی منابع آب, 2018 A stilling basin is one of the energy dissipaters downstream of a spillway. The place of maximum pressure caused by jet impact and the effect of various factors on the amount and location of pressure are important factors in designing of stilling basin ...
