This review paper concerns the application of numerical methods of the Godunov type to the computation of approximate solutions to free-surface
gravity flows modelled under a shallow-water type assumption. In the absence of dissipative processe[...]

For debris flow hazard assessment often simple rheologic models are used in engineering practice. A vertically rotating drum has been constructed to study the flow behaviour of debris flow material in a laboratory environment. We provide a detai[...]

Chlorine is the most common type of disinfectant in water supply networks. However, it is a highly unstable oxidizing agent and also known to be consumed in the bulk liquid phase (bulk decay) and at the pipe wall (wall decay). This experimental [...]

An alternative approach for the transient analysis of a pipe network is explored in this paper. If the condition of steady oscillatory flow is met, then transient analysis will show that the impedance matrix method at surge responses is identica[...]

The flow and transport of suspended sediment in open-channel flows over smooth-rough bed strips were simulated numerically. The flow equations were solved with the aid of the Reynolds stress model. Simulated flow structures are provided and comp[...]

The pipe flow equations for diameter and discharge are given separately for laminar and turbulent flows; and no equation is available for transition between these flows. As the diameter or discharge is unknown, it is not possible to find the flo[...]
