In this work, we investigate the temporal evolution of the jet-driven scour depth in a pothole
lying on a cohesionless granular bed by using diverse approaches. First, we present new …

In parallel to their most frequent application as an auxiliary dam spillway, piano key weirs
(PKWs) are also installed on low-head barrages in combination with run-off-the-river power …

The current study deals with the depth of scour at the location of impact between a free fall
jet and a riverbed. The current study is based on extensive laboratory experiments that were …

Rock and stepped gabion weirs are peculiar hydraulic structures that received relatively little
attention in technical literature. Nevertheless, they can be successfully used for river …

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 …

The characteristics of scoured regions behind embankments generated by the 2011 Great
East Japan tsunami were investigated along the Abukumagawa River, where severe …

Piano key (PK) weirs are used in a variety of flow control structure applications, including
spillway crests and open channel diversion structures. However, to the best of authors' …

Key Points The scour mechanism caused by a jet impinging on a granular bed was
analyzed under variable jet discharge and clear‐water condition Scour evolution is …

The results of experiments on the local scour due to free fall jets are presented in this paper.
Experiments were conducted for various values of the densimetric Froude number, the …

In this study, the effect of the structure geometry, the bed material, and the river hydraulic
conditions on the scour morphology downstream of the stepped-baffle weirs are …
