【 摘 要 】

Predicted runup elevations for given waves and nearshore profile are confirmed as accurate by large tank and field studies with over 400 published measurements, the majority exceeding 1 m above static water level. Predictions are provided by a public-domain computer code incorporating detailed empirical guidance for smooth slopes developed by Stoa (1978). This model examines the geometrical match with specified situations, applies the composite-slope method of Saville (1958) where necessary, treats barrier texture using standard runup-reduction coefficients, and executes suitable interpolation and iteration for a fully consistent runup estimate. With irregular wave action, basic empirical guidance for uniform waves gives the mean runup elevation from the mean wave description. There is definite agreement between predictions and measurements for smooth or rough barriers with uniform waves, for controlled irregular waves, and for field situations.
