Sensitivity analysis is well recognized as being an important aspect of the responsible use of
hydraulic models. This paper reviews a range of methods for sensitivity analysis. Two …

There is growing concern that flooding is becoming more frequent and severe in Europe. A
better understanding of flood regime changes and their drivers is therefore needed. The …

Full-scale fluvial flood modelling over large catchments has traditionally been carried out
using coupled hydrological and hydraulic/hydrodynamic models. Such a traditional …

This paper presents a well-balanced numerical scheme for simulating frictional shallow
flows over complex domains involving wetting and drying. The proposed scheme solves, in …

This paper proposes a numerical technique that in essence is based upon the classical
staggered grids and implicit numerical integration schemes, but that can be applied to …

Shallow water equations with a non-flat bottom topography have been widely used to model
flows in rivers and coastal areas. An important difficulty arising in these simulations is the …

In this paper, the effects of water on obstacles in the dam break flow problem are
investigated numerically. The numerical method is based on the Navier–Stokes equations …

We evaluate a new depth-averaged mathematical model that is designed to simulate all
stages of debris-flow motion, from initiation to deposition. A companion paper shows how …

Many natural terrains have complicated surface topography. The simulation of steep-fronted
flows that occur after heavy rainfall flash floods or as inundation from dyke breaches is …

In some previous works, the authors have introduced a strategy to develop well-balanced
high-order numerical methods for nonconservative hyperbolic systems in the framework of …
