Evolution of local scour downstream of Type A PK weir in non-cohesive sediments
Journal of Hydrology and Hydromechanics, 2022 A large-scale piano key weir laboratory study was conducted to investigate the evolution of the scour process occurring in the downstream basin for two non-cohesive granular bed materials, including the analysis of scour-hole geometry and patterns at ...

Effect of debris accumulation on scour evolution at bridge pier in bank proximity
Journal of Hydrology and Hydromechanics, 2021 Large debris transported by flood affects scour features at bridge piers and increases the risks of structural failure. Geometric characteristics of the debris and the relative position of the pier with respect to the river bank are important parameters ...

Experimental investigation of bed evolution resulting from dam break [PDF]
Journal of Hydraulic Structures, 2020 This study examines the relations of structures and shapes of streambed evolution after dam break floods. A flume was used to simulate dam-break floods with variations of initial upstream water levels and variance, from uniform to graded, of the bed ...

Characteristics of seabed scouring around sea platform of Hangzhou Bay Sea-Crossing Bridge
Shuili Shuiyun Gongcheng Xuebao, 2021 The sea platform of Hangzhou Bay Sea-Crossing Bridge is near the center the bridge. The pier groups under the platform combined with ramp piers and main bridge piers compose complex bridge pier groups which induce significant scour around sea platform ...
