Comparison of Wave Run-Up Formulas by Flume Experiments

The wave run-up formulas from the Code of Hydrology for Sea Harbour (CHSH), the Code for design of levee project (CDLP) and Hunt are all widely used, but they are in different forms of mathematical equations. In this paper, some flume experiments for wave run-up are made to examine these formulas. The tests show that the wave run-up formula from Hunt is in good agreement with the experiments. The wave run-up formula from CDLP has been usually used in steep slopes, while the tests show that it is also in good agreement with the experiments in the small slope flume. The wave run-up formula from CHSH is also used mainly in steep slopes, it brings significant error of the wave run-up calculation contrasting with the experiments.
