\section{Radial dam break on a dry bed}

A radial dam break test problem involving a dry bed. Should show a rarefaction fan. Note that the reference solution is found from the 1D FVM for SWE involving varying width and topography. See a paper of Roberts and Wilson~\cite{RW2011}.


\subsection{Results}

We should see excellent agreement between the reference and numerical solutions.
