Abstract

[automatically translated] The plan position of the shoreline, just of charge, is determined through the use of aerial images and used pe r the historical evolution reconstruction of coastlines. However, the information east rats from these images, describing the instantaneous boundary water-earth, allow the individ fication of the shoreline exclusively as dry-wet edge just at the time of the shooting. For a more accurate location of the shoreline, it is therefore necessary to quantify, in addition to tidal effects and sediment transport, the effects produced by the wave of that position, and in particular the so-called ru n-up. This paper studies the run-up in a natural ggia indicator of weak sloping falling in western Sicily. The study surveyor orfologico site precedes the hydraulic study, that starting from the measures waves off, through their transposition and propagation simulated with a mathematical model ello, leads to estimates of the waves along the coast. The latter are ut ilizzate to evaluate the run-up either by a known empirical formula is using a numerical model to Boussinesq with a new boundary condition for the shore line. Comparison of the results with field measurements shows that ir best esults are achieved with the empirical formula, in which, however, is necessa rio calibrate the coefficients with in situ measurements. The latter are ut ilizzate to evaluate the run-up either by a known empirical formula is using a numerical model to Boussinesq with a new boundary condition for the shore line.
