PHYSICAL MODEL AND REVISION OF THEORETICAL RUNUP

Jose de la Peña, Jose Sanchez, Roberto Diaz, Manuel Martin

Abstract


Several formulations deduced from empirical studies are available for runup estimation. Scattering is high when applied to practical cases. Through a state of the art best formulations are chosen. This equations are also studied in a physical model carried out in the Laboratory for Maritime Experimentation of CEDEX with three beaches with slopes 1/20, 1/30 and 1/50 and with sand bed. The performance of each formulation is discussed. A new formulation is proposed in order to give more weight to the beach slope thus reducing scatter.
