Investigating skimming flow conditions over stepped spillways using particle image velocimetry [PDF]
Turbulent flow over stepped spillways can be considered the most significant flow that can cause severe problems at the downstream side, near the toe of the structure, such as sediment erosion which normally occurs due to the high amount of water energy.

Modelling atmospheric dry deposition in urban areas using an urban canopy approach [PDF]
Atmospheric dry deposition is typically modelled using an average roughness length, which depends on land use. This classical roughness-length approach cannot account for the spatial variability of dry deposition in complex settings such as urban ...

Aeration characteristics for skimming flow along the pre-aerator stepped spillways
Pre-aerator stepped spillways,where the aerator is placed prior to the primary step in the stepped spillway,can form a cavity chamber at the bottom to produce enough aeration concentration to avoid the cavitation erosion.

Investigation of the effects of some processing conditions on the fate of oxytetracycline and tylosin antibiotics in the making of commonly consumed cheeses from the East Mediterranean [PDF]
Background and Aim: Transfer of antibiotics from raw milk to derived products is directly related to the processes involved in the manufacturing of dairy products, including East Mediterranean cheeses, since these have particular flow diagrams of ...

Distribution of Pressures on Modified Stepped Spillway by Using Toothed-Steps [PDF]
In the present study a new steeped spillway shape at which “toothed steps” have been adopted instead of traditional steps to enhance the amount and distribution of water pressure along the chute of the stepped spillway. Experiments were conducted under a

Standing waves of the stepped dropshaft in a deep tunnel stormwater system
The deep tunnel stormwater system, consisting of dropshafts and underground tunnels, is used to alleviate or prevent urban water problems associated with extreme rainfall events. The stepped dropshaft can transport surface runoff to the tunnels with high

Numerical simulation of flow on circular crested stepped spillway
The spillways are one of the most important hydraulic structures used in river engineering, dam construction, irrigation, and drainage engineering projects. Recently, a new type of such spillways with a circular crest has been proposed.

Effects of Inclination Angles on Stepped Chute Flows
Owing to its effective energy dissipation and aeration, a stepped spillway is commonly used for flood release in hydraulic projects. Its conventional design features horizontal step surfaces.
