Large Eddy Simulation (LES) is used to investigate the 3D-transport of sediment suspension in an open channel flow at a Reynolds number based on the frictional velocity.An Eulerian model was employed to represent the fluid and the sediment phase[...]

Effective extension of a finite difference model for the solution of the shallow water equations to handle rapidly varied, transcritical flows is presented, based on a semi-implicit, nondirectional, operator splitting formulation on a staggered [...]

A new method of leak detection in pipelines is introduced based on the inverse transient analysis. The transient state can be initiated in pipes by closing the downstream end valve. The time history of pressure fluctuations is measured at the va[...]

The critical stream power criterion may be used to describe the incipient motion of cohesionless particles of plane sediment beds. The governing equation relating “critical stream power” to “shear Reynolds number” is developed by using the prese[...]

The analytical solution of an one-dimensional morphodynamic model of a river reach with nonuniform grain size material under unsteady flow conditions is discussed. The model Harmonic River assumes an instantaneous propagation of the water flow a[...]

Experimental model data are compared with numerical computations of dike-break induced flows, focusing on the final steady state. An idealized scale model was designed reproducing the specific boundary conditions of dike breaks. Discharges, wate[...]

A new model is proposed to predict the bed topography in steep open channels once the bed stability is exceeded. Existing relationships describe bed stability by defining an entrainment state, usually expressed by a threshold shear stress or a d[...]

The available scour equations for bridge pier are mostly deterministic in nature, which do not consider uncertainties of various scouring parameters adequately. A reliability-based assessment of bridge pier scour depth is of paramount importance[...]
