Experimental repetitions and blockage of large stems at ogee crested spillways with piers [PDF]
Journal of Hydraulic Research, 2018 Large wood is often transported by rivers into reservoirs during heavy rainfall events. When a critical section like a spillway is blocked and discharge capacity reduced, an uncontrolled increase o...

ANALITICAL AND ARTIFICIAL NEURAL NETWORK MODELS OF DISCHARGE VALUE PASSING OVER OGEE SPILLWAY [PDF]
, 2017 In this study, analytical and Artificial Neural Network (ANN) models’ output of the discharge value, passing over Ogee Spillways, were compared. For this aim, a flume having 7.5 cm width, 15 cm depth and 5 m length, was used in the laboratory.

Stepped Spillway Hydraulic Model Investigation
Tikrit Journal of Engineering Sciences, 2006 An experimental hydraulic model investigation was conducted to evaluate the performance of a stepped overflow spillway . The spillway tested has a standard ogee profile with continuous steps cut into a straight portion of downstream face from tangential ...

Pressure and velocity on an ogee spillway crest operating at high head ratio: experimental measurements and validation [PDF]
, 2017 peer reviewedThis paper aims at validating pressure and velocity measurements conducted in two physical scale models of an ogee spillway crest operating at heads largely greater than the design head.

Blockage of driftwood and resulting head increase upstream of an ogee spillway with piers [PDF]
, 2019 Accumulations of floating debris in reservoirs can have negative impacts on the safe operation of a dam. Thus, adequate spillway design in view of driftwood is of paramount importance.

Analysis of discharge rates in rectangular slit, ogee, and sharp-crested weirs
Frontiers in Built EnvironmentClimate change has made flash floods increasingly common. It's crucial to have confidence in the structural integrity of dams during a flash flood. According to the International Commission on Large Dams (ICOLD), approximately one-third of dam failures ...

Investigating the bottom free surface nappe (ogee profile) across a sharp-crested weir caused by the flow in an asymmetrical approach channel [PDF]
, 2015 The shape of an ogee spillway is based on the shape of the lower nappe of water flowing over an aerated sharp-crested weir. At the design discharge, this shape minimises the possibility of sub-atmospheric pressure occurring on the spillway and ...
