Maximum drop in breakwater dikes of loose parts with S-profile
Abstract
This paper focuses on the evaluation of the rundown (Rd/H ) on the breakwaters with “S" prole (DRPS-S). A complete integral methodology is proposed, that starts with the definition of the “S" profile. Afterwards the necessary steps to the geometric design of a DRPS-S are presented. This methodology is presented in the par-paper (Evaluation of the runup, Ru), which focuses only on the analysis of the runup. Later, all the variables involved in the numerical modelling are presented. The numerical calculations, made with the software OpenFOAM®, allow the evaluation of the rundown originated by each proposed sea state. A statistical analysis of the obtained results was made, and a statistical fitted function that allows the evaluation of Rd/H as a function of Iribarren number ξ, is proposed. Finally, a comparison between the numerical results, and two mathematical formulations from the literature is made. Adjustment numerical-factors to these equations are proposed, which allows the evaluation of the rundown with major confidence for hese type of breakwaters.
