Wave Runup in a Sand Bed Physical Model

de la Peña, Jose M. / Sánchez-González, Jose F. / Díaz-Sánchez, Roberto

Abstract

The extreme phenomena induced by climate change have generated new interest in analyses of wave runup on beaches. Extreme runup quantification is essential for coastal management and protection against coastal flooding. Several formulations deduced from empirical studies are available for runup estimation, although scattering is high when applied to practical cases. This paper presents the results of a physical model experiment carried out in the Laboratory for Maritime Experimentation at CEDEX on three sand bed beaches with uniform slopes of $1 / 20$ , $1 / 30$ , and $1 / 50$ . The performance of each formulation is discussed with the aim of choosing the best formulations available for coastal engineering. A new formulation is proposed that accounts for beach slope. Choosing the most extreme beach profile prior to a storm reaching the shore in this formulation provides the required model for risk analysis.
