In this paper, the laboratory data were compared with computational fluid dynamics (CFD)
Flow3D for predicting the beginning of sediment incipient motion in rigid boundary channel …

In high-head dam projects, chute aerators are commonly applied as artificial aeration
devices to prevent cavitation erosion damage in high-speed spillway and tunnel flows …

Paper history: Recently, the investigations studies of simulating flow over spillways have
increased using numerical models. Due to its important structure in the dams to pass flood …

Due to the high flow velocity and easy cavitation of high-head drainage tunnels, it is usually
necessary to set up aeration facilities. In particular, when the bottom slope of the tunnel is …

The purpose of this work is to evaluate the impacts of flow rate on cavitation and abrasion in
ogee spillways using numerical simulations. One of the most complicated and frequent …

In the field of water conservancy engineering, a spillway is a common hydraulic structure
that plays a role in flood discharge and dam protection. The selection of the weir surface …

ABSTRACT A spillway dam, constructed concurrently with concrete or masonry, is a vital
infrastructure designed to provide the controlled release of surplus water that surpasses the …

The spillway tunnel for water discharging is very important in water conservancy and
hydropower engineering. Spillway tunnel with inclined and elbow part near the outlet can be …

In the prototype observation of a huge water conservancy project, flood discharge in the
deep outlets showed strong fluctuations in the downstream of step-type aerators. Intermittent …

Submerged spillways with large capacity outlets are generally provided below the dam crest
to perform the dual functions of flood disposal and sediment flushing. Flood water passing …
