A supercritical open-channel flow can skirt an emerged obstacle by using two distinct forms of workaround: a detached hydraulic jump or a so-called wall-jet-like bow wave. These two forms stem from the properties of ...

The pier scour caused by flood waves is analyzed, introducing the dimensionless effective work by the flow on the sediment bed around the pier, W*. The three-parameter exponential function is adopted to relate the normalized ...

This paper presents the results of laboratory experiments conducted to study the effects of varying ambient stratification strengths, characterized by the buoyancy frequency N, on the dynamics of a buoyant plume propagating ...

Erosion of a saturated sand bed by a vertically upward water jet was studied experimentally. Direct observations on the behavior of sand-bed erosion were obtained by increasing the flow rate at a small increment until ...
