Enhancements in reservoir flood risk mapping: example application for Ulley

open access: yes, 2014
In July 2007, at Ulley Reservoir, South Yorkshire, a catastrophic dam failure was narrowly avoided due to emergency preventative actions. During the event, a number of homes were evacuated and roads were closed for precautionary measures.

Recent trends in stepped spillway design: behaviour without sidewalls

open access: yes, 2012
Until now, hydraulic research of stepped spillways has focused on characterizing aspects as: the different types of flow that occur on the dam, the air inception processes, the potential negative effects associated to the risk of cavitation, the energy ...

Dynamic Pressure Fluctuations in Stepped Three-Side Spillway [PDF]

open access: yesIranica Journal of Energy and Environment, 2012
One type of outlet works in dams are Three-side spillways that despite of their hydraulic limitations and construction problems, they were being selected, in storage dams, as best option under specific topographical conditions. Considerable energy losses

Experimental and computational study on flow over stepped spillway

open access: yes, 2019
The flow over a stepped spillway has complex nature, and its characteristics are remarkably different from other kinds of spillways. This study conducts experimental investigations and numerical simulations on the flow behavior (velocity, concentration ...

Geometry effects on energy dissipation over stepped spillway

open access: yes, 2017
The stepped spillway is a hydraulic structure, mostly used in dams. Normally, stepped spillways were designed to increase the energy dissipation level and hence decrease the risks at downstream.

Stepped spillway Downstream of a Piano Key Weir - Critical length for uniform flow [PDF]

open access: yes, 2013
peer reviewedRecent researches showed the rapid aeration of the flow downstream of piano key weirs. This could be related to the specific geometric features of the structure, creating several interacting flows and jets downstream.
