This paper reports the results of an integrated atmospheric and wave run-up forecasting system, validated with in situ measured data, for the coastal site of Bagnoli, inside the Gulf of Pozzuoli, in the Thyrrenian Sea. A modelling chain consisting of Weather Research and Forecasting model, Wave Watch 3 model and a run-up calculator was used to obtain the (Formula presented.) levels on the beach of Bagnoli, in the framework of the rehabilitation project of the industrial site. Hindcasted waves were validated with observed ones in intermediate depth, while run-up excursions were validated using video-monitoring system located on the beach. The run-up observations were obtained by time stack images analysed using video-monitoring system. An error compensation algorithm was implemented for the correction of the systematic deviations from the DGPS more precise measurements. Among the different schemes chosen for wave run-up prediction, the one of Stockdon et al. [Empirical parameterization of setup, swash, and runup. Coast Eng. 2006;53(7):573–588] was found to be outperforming in matching with the observed run-up levels. This result was expected because of the structure of this formula, which takes into account both the set-up and swash run-up contributions.
