Introducing a Relationship for Estimation of the Sediment Transport Rate through Rockfill Structures

Rockfill dams are accounted as useful measures in watershed management projects. How-ever, the sediment transport through the rockfill materials, could impact their lifetime duration. Previously, researches have been conducted to describe the various hydraulically issues of the flow passing through these structures However; there is no general relationship to estimate the sediment transport rat...

Prediction of scour dimension in the Plunge Pools below Outlet Bucket with Artificial intelligence method

Accurate prediction of sediment scour hole dimensions downstream of hydraulic structures, e.g. the outlet bucket, is a complex and not straight forward engineering problem encountered worldwide. Because of the complexities of the study, its comprehensive, simultaneous including water flow,  sediment and applying all of the effective variables involved in scouring it is not easy possible. Dimens...

Sediment Transport in Unsteady Flow Conditions

Sediment transport under unsteady flow condition is studied experimentally. In the first step, sediment transport under different steady flow conditions was measured and an empirical equation was derived for its calculation. In the next step, two continuous and three stepwise hydrographs were generated in the flume, and their sediment transport rate was measured. The continuous hydrographs were...

Influence of air entrainment on rock scour development and block stability in plunge pools

Influence of air entrainment on rock scour development and block stability in plunge pools The impingement of high-velocity water jets on plunge pools, such as it occurs downstream of spillways of high-head dams, may cause scour on the rock foundations. The scour process is the result of complex and consecutive physical phenomena. Turbulence plays a major role, especially in the jet development...
