Abstract

In the present paper the run-up of random waves was calculated by means of a numerical method. In situ measurements based
on a video imaging technique have been used for the validation of the present numerical model. The on-site run-up
measurements have been carried out at Lido Signorino beach, near Marsala, Italy,along a transect, normal to the shore. A video
camera and a linear array of rods have been used to obtain field data. Numerical simulations with a 1DH Boussinesq-type of
model for breaking waves which takes into account the wave run-up by means of a Lagrangian shoreline model have been
carried out. In such simulations random waves of given spectrum have been propagated in a numerical flume having the same
beach slope of the measured transect. The comparison between registered and estimated run-up underlined an acceptable
agreement. Indeed, the numerical model tends to underestimate the actual R 2% , with the maximum underestimate being less than
24%, which is a reasonable error in many cases of engineering interest.

1. Introduction

In the field of coastal engineering, the investigation of the swash zone process has become recently a very hot
topic, due to its relevance in the context of coastal flooding and erosion phenomena.
