... flume follows the S-shape distribution law. The flow rate has a larger velocity gradient only at boundaries, while in the central area of the flow field, the velocity gradient remains small and the curve fits a cubic function. The radial distribution of velocity is linear and the velocity decreases from...

There exist some slight discrepancies in the water height at the upward and downward slopes immediately away from the crest for the incompressible SPH model. The subsequent maximum run-up height on a vertical boundary agrees well with the published...
