Abstract: Physical model data for subcritical and supercritical flow has been collected and analyzed to determine a statistically-based relationship for wave runup heights in a trapezoidal channel. It is anticipated that this investigation may lead to an analytical approach which may quantify the uncertainty in computed water surface elevations due to perturbation-induced wave activity. This information may be combined with traditional one-dimensional numerical analysis to provide statically-based maximum water surface elevations which can be used to establish top of wall levee/wall design for flood control channels.
