An explicit two-dimensional conservative finite volume model for shallow water equations is formulated and tested. The algorithm for the mass and momentum fluxes at the control surface of the finite volume is obtained from the solution of the Bh[...]

Elevated levels of dissolved gas in the spillway stilling basin, which are responsible for gas bubble disease in fish, constitute an important negative environmental effect of dams. Bubbles, entrained when a plunging jet impacts the tailwater po[...]

Some hydraulic applications are characterized by systems originally flowing in free-surface conditions that subsequently undergo flowregime transition into pressurized flow during rapid filling events. Currently, models simulating these flow reg[...]

Mathematical models of blood circulation in the human arterial network are examined in the paper. In particular, a complete two-dimensional model is proposed in the hypothesis of gradually varied flow. Vessels are considered as elastic and blood[...]

Discharge predictions using four codes suitable to modelling flood extent are compared to predictions derived using theoretical and empirical methods.
The model codes vary in complexity but represent the types of code used in practical applicat[...]

The results of a comparison between laboratory tests and numerical modeling for flow around permeable structures are presented. Three different structures are experimentally considered, first one is solid and second one is permeable structures. [...]

Fish habitat rehabilitation projects often use paired stream deflectors to increase bed shear stress and maintain a deep pool. Many of these projects have been unsuccessful, mainly because of the lack of knowledge of the complex three-dimensiona[...]

The wave-induced boundary layer flow over a rippled bed is studied. A two-dimensional model aiming to solve the flow in the vicinity of the bed has been developed. First the model is tested for a flat bed case and comparison is made with experim[...]

In this paper, we focus on the influence of temporal variations in the regional hydraulic gradient, particularly, on the impact of temporal variations in the boundary conditions on the spreading of solute plumes in homogenous aquifers. We examin[...]

In recent costal modeling practice physical models are constructed in undistorted scales preserving the Froude similarity. Correction for scale effect is obtained a posteriori by means of a distortion coefficient, which multiplies the final quas[...]

The flow field behind a flat plate suspended in an open channel is investigated using LDV. The formation of a gap between the plate and channel bed produces a flow that is different from the flow around a wall-mounted bluff body. The gap can be [...]

Chemical grouting may be defined as the injection of chemical mixtures, known as grouts, into the pore space of the soil. It is extensively used for ground stabilization in the construction industry. The mechanism by which injected grout permeat[...]
