    638638\subsection{Runup of solitary wave on circular island wavetank validation}
    639639
    640 This section will describe the ANUGA results for the experiments conducted
    641 by Briggs et al (1995). Here, a 30x25m basin with a conical island is situated near
    642 the centre and a directional wavemaker is used to produce planar solitary waves of
    643 specified crest lenghts and heights. A series of gauges were distributed within the
    644 experimental setup. As described by Hubbard and Dodd \cite{Hubbard02}, a number of researchers
    645 have used this benchmark problem to test their numerical models. {\bf Jane: check
    646 whether these results are now avilable as they were not in 2002}. Hubbard and Dodd
    647 \cite{Hubbard02} note that
    648 a particular 3D model appears to obtain slightly better results than the 2D ones reported
    649 but that 3D models are unlikely to be competitive in terms of computing power for
    650 applications in coastal engineering at least. Choi et al \cite{Choi07) use a 3D RANS model
    651 (based on the Navier-Stokes equations)
    652 for the same problem and find a very good comparison with laboratory and 2D numerical
    653 results. An obvious advantage of the 3D model is its ability to investigate the
    654 velocity field and Choi et al also report on the limitation of depth-averaged
