On a spillway chute, a stepped design increases the rate of energy dissipation on the chute itself and reduces the size of a downstream energy dissipater. Up to date, the effects of step roughness on the flow properties remain unknown despite th[...]

This study reexamines the mean velocity scaling as well as higher order turbulent moments in a uniform smooth open channel flow with three different aspect ratios. In the overlap region, the velocity profiles follow the classical logarithmic law[...]

This paper concerns the location in flow plan of the laterally adjacent erosion-deposition zones (“deeps” and “hills”) in sine-generated meandering streams. The aim of the paper is to gain insight into how the location of the aforementioned eros[...]

A new “vortex-drag” approach is proposed to compute the rate of dissipation of mean-motion energy in alluvial streams flowing over mobile bed forms. 1D-routing exercises strongly suggest that, for a given depth and energy-slope, there exists a c[...]

Transverse mixing is arguably more important in water quality management than either vertical or longitudinal mixing, especially when dealing with the discharge of pollutants from point sources or the mixing of tributary inflows. A finite volume[...]

This paper shows the results of an experimental work on the spilling type breaking flow field produced by a hydrofoil positioned in a uniform current. From the examination of the Laser Doppler Anemometer results downstream of the hydrofoil a flo[...]

The propagation of pressures generated by wave or jet impact into water filled cracks and fissures can create internal bursting pressures and resulting damages in structures such as blockwork breakwaters or coastal rock cliffs. Experimental inve[...]

It is impossible to know beforehand the planforms of a stretch of beach without being first aware of the maritime climate affecting it. This article describes a procedure for objectively calculating the uncertainty associated with the prediction[...]

Segregation and settling of fine solids particles in hyperconcentrated homogeneous sand-water mixtures were studied for un-sheared and sheared conditions in settling columns in the laboratory. Specific solids percent values were able to be deter[...]

Pulsating turbulent flow is studied for four regimes: steady, quasi-steady, relaxation, and quasi-laminar in a rectangular straight asymmetric diffuser, a generic model of the diffuser found at the end of most Kaplan and Francis type hydropower [...]

Accurate information of pipeline and system properties is crucially important for precise computer simulation of pipe networks. Even though inverse transient analysis (ITA) techniques have been widely investigated for leak detection and friction[...]

A new technique for the detection of leaks in a pipeline is presented utilizing its frequency response. In the system frequency response, a leak increases the amplitude of pressure oscillations at the even harmonics. Such an increase in amplitud[...]

The problem of adjusting the discharges of a free surface flow canal to meet demand by farmers at particular diversion points requires a certain ability to control the canal and also needs a study of flow transients. This article presents an alg[...]

The fall velocity of coastal or river sediment is usually calculated by literature formulas. Many authors have highlighted that this procedure is not really suitable for evaluating the average fall velocity of the natural sediment as a whole. A [...]
