+Non-linear models however require much finer resolution in order to capture
 the complexity associated with the water flow from off to onshore. By contrast, the data
 resolution required is typically of the order of tens of metres.
 The model ANUGA \cite{ON:modsim} is suitable for this type of non-linear
 modelling.

 resources than the typical hazard model making it infeasible to use it
