This test case is the first benchmark
problem of
"The Third International Workshop on LongWave Runup Models". A
solitary wave runs up a plane inclined beach. Reference solutions
are provided by the initialvalueproblem (IVP) technique introduced
by Carrier et al [10].
Figure 151 illustrates the topography and wave profiles at
t=160, 175 and 220 seconds. Figure 152 gives the
convergence in wave elevation error with spatial resolution.
Figure 151: Topography, analytical (lines) and numerical
(symbols) wave profiles for the times indicated in the legend. The
numerical results are for a maximum spatial resolution of ≈
3.6 metres. 
Figure 152: Convergence of the average and maximum errors
with spatial resolution. The errors are for the predicted wave
profile at t=220 sec.
