... variation for each element and flags those elements which have a high variation as needing a larger value of a for shock capturing. Note that this would work even in a Galerkin scheme since ... the comparison is to actual flume data. The comparisons are made to the water surface heights and timing of the shock passage. The final case is a steady-state comparison t...

... go to smaller grid spacing. Values of C, less than 1 appear to lag the analytic shock and Cs greater than 1 leads the analytic shock. With the largest C, the calculated shock speed ... 1 .5 the time of arrival is 3 .55 sec which is about 0.1 sec late (3 percent).
