Abstract: The present paper discusses an experimental study on the critical submergence for lateral dual horizontal intakes that are placed in a row and perpendicular to a uniform approach flow. The effect of clear spacing between ...

Abstract: Piano Key Weirs (PKWs) are often preferred over other spillways for the dam rehabilitation due to high discharging capacity. The present study investigates scour downstream of three cycles of PKWs with and without solid ...

Abstract: This study aimed to investigate the critical suction velocity required for lifting sediment off the bed under hydrosuction. Flow characteristics below the suction pipe under unbound and bound conditions were studied ...

Abstract: Rectangular broad-crested gabions are economical- and environmental-friendly structures that are constructed to manage the transport of sediment in steep slope rivers. This study aims to study the pattern and extent of ...

Abstract: Block ramps are a short length of a steep channel armored with rocks, which produce high dissipation of energy. This technical note presents the results of experiments performed on a ramp having a staggered arrangement of ...

Abstract: This investigation deals with the mechanics of movement of singular quartz gravel and coarse sand riverbed particles upstream and over the inlet key of three Type A piano key weir (PKW) models, which were recorded with a ...

Abstract: The existing equations for the discharge coefficient of Piano key weirs (PKWs) use a limited range of experimental data, which means that they are inappropriate for wide parametric ranges that might lead to significant ...
