A one-dimensional numerical model for dam failure due to flow overtopping is developed.
The MacCormack explicit finite difference scheme is used to solve the one-dimensional …

Predicting how a flood defence structure, such as a river or coastal embankment, behaves
under varying load conditions is an essential part of undertaking a flood risk assessment …

The mouth dynamics of small temporary open estuaries play a key role in their overall
functioning. Intermittent breaching of the sand barriers of these systems leads to large …

The process of breach erosion in sand-dikes is described. This process consists of five
stages. For the final two stages three breach types are distinguished, depending on the …

A mathematical model is formulated to describe incipient breaching of coastal barrier
islands. The model is based on the assumptions of idealized breach morphology and is …

Sediment transport rate determination plays an essential role in mathematical models of
embankment dam breaching. The sediment transport formulae commonly used today were …

Intermittent breaching of sand barriers at temporary open estuaries plays a key role in the
functioning of these systems. In addition to their ecological impacts, breaching events can …

A series of large-scale experiments are conducted to investigate the breaching process of
sand dikes under wave overtopping. The dikes are constructed with uniform sand, covered …

The set-up and results of a field experiment on sand-dike breach erosion are described. It is
found that the breaching process for the 2.2 m high sand-dike is similar to that in Visser's …
