+\chapter{Restrictions and limitations on \anuga}
+
+Although a powerful and flexible tool for hydrodynamic modelling, \anuga has a
+number of limitations that any potential user need to be aware of. They are
+
+\begin{itemize}
+  \item The mathematical model is the 2D shallow water wave equation. 
+  As such it cannot resolve vertical convection and consequently not breaking 
+  waves or 3D turbulence (e.g.\ vorticity).
+  \item The finite volume is a very robust and flexible numerical technique, 
+  but it is not the fastest method around. If the geometry is sufficiently 
+  simple and if there is no need for wetting or drying, a finite-difference 
+  method may be able to solve the problem faster than \anuga.
+  %\item Mesh resolutions near coastlines with steep gradients need to be...   
+  \item Frictional resistance is implemented using Manning's formula, but 
+  \anuga has not yet been validated in regard to bottom roughness
+\end{itemize}
