NEW PROCESS BASED EQUATION FOR A STATIC EQUILIBRIUM BEACH PLANFORM

Equilibrium planform formulations of beaches are engineering tools for providing solutions beach erosion problems. They aim at defining the final orientation on a scale years and thus they used evaluating shoreline response due to human interference (ports, breakwaters, protection works…etc). These create solution numerous coastal stability The Parabolic Bay Shape Equation (PBSE) proposed by Hsu Evans (1989) is most equation allow solve However, these shape equations valid under certain simplifications. Therefore, unable determine when bathymetry complex, with rocky areas or/and islands. this study present new equilibrium (Gainza et al. 2018) that overcomes problem previously mentioned. What more, an extension model presented in order modeled given day.
