Abstract. The paper presents an application of shoreline monitoring aimed at understanding the response of a beach to single storms and at identifying its typical behaviour, in order to be able to predict shoreline changes and to properly plan the defence of the shore zone. On the study area, in Jesolo beach (northern Adriatic Sea, Italy), a video monitoring station and an acoustic wave and current profiler were installed in spring 2013, recording, respectively, images and hydrodynamic data. The site lacks previous detailed hydrodynamic and morphodynamic data.Variations in the shoreline were quantified in combination with available near-shore wave conditions, making it possible to analyse the relationship between the shoreline displacement and the wave features. Results denote characteristic patterns of beach response to storm events, and highlight the importance of improving beach protection in this zone, notwithstanding the many interventions experimented in the last decades. A total of 31 independent storm events were selected during the period October 2013-October 2014, and for each of them synthetic indexes based on storm duration, energy and maximum wave height were developed and estimated. It was found that the net shoreline displacements during a storm are well correlated with the total wave energy associated to the considered storm by an empirical power law equation. A sub-selection of storms in the presence of an artificial dune protecting the beach (in the winter season) was examined in detail, allowing to conclude that the adoption of this coastal defence strategy in the study area can reduce shoreline retreat during a storm. This type of intervention can sometimes contribute to prolonging overall stability not only in the replenished zone but also in downdrift areas.The implemented methodology, which confirms to be economically attractive if compared to more traditional monitoring systems, proves to be a valuable system to monitor beach erosive processes and provide detailed indications on how to better plan beach-maintenance activities. The presented methodology and the proposed results can therefore be used as a basis for improving the collaboration between coastal scientists and managers to solve beach erosion problems, in locations where data are scattered and sporadic.

“…1), which is the area of interest of this paper, the ECMWF surface wind fields result in general underestimated with respect to satellite scatterometer winds (Cavaleri and Bertotti, 2004;Zecchetto and Accadia, 2014). In the operational activity, a solution of applying an enhancing factor to the ECMWF wind speed over the Adriatic Sea has been attempted (Cavaleri and Bertotti, 1997;Zampato, 2005;Zampato et al, 2006). Since then, the importance of the scatterometer winds in both the understanding of the wind structure (Zecchetto and De, 2007) and the estimation of the performances of atmospheric models (Accadia et al, 2007;Zecchetto et al, 2012;Zecchetto and Accadia, 2014) has grown, thanks to the scatterometer's enhanced spatial resolution and, in some period, to the enhanced revisit times.…”

Abstract. The paper presents an application of shoreline monitoring aimed to understand the response of a beach to single storms and to identify its typical behaviour, in order to be able to predict shoreline changes and to properly plan the defence of the shore zone. On the study area, in Jesolo beach (Nothern Adriatic sea, Italy), a video monitoring station and an acoustic wave and current profiler were installed in spring 2013, recording respectively images and hydrodynamic data. The site lacks of previous detailed hydrodynamic and morphodynamics data. Variations in the shoreline were quantified in combination with available nearshore wave conditions, making it possible to analyse a relationship between the shoreline displacement and the wave features. Results denote characteristic patterns of beach response to storm events, and highlight the importance of improving beach protection in this zone, notwithstanding the many interventions experimented in the last decades. A total of 31 independent storm events were selected during the period October 2013–October 2014, and for each of them synthetic indexes based on storm duration, energy and maximum wave height were developed and estimated. It was found that the mean shoreline displacements during a storm are well correlated with the total wave energy during the considered storm by an empirical power law equation. A sub-selection of storms on beach protected by artificial dunes (in winter season) was examined in detail; we can conclude that the extensive adoption of artificial dunes in the study area was useful in the past also to reduce shoreline retreat during the storm. This type of interventions can sometimes contribute to prolonged overall stability not only in the replenished zone but also in down drift areas. The implemented methodology, which confirms to be economically attractive if compared to more traditional monitoring systems, proves to be a valuable system to monitor beach erosive processes and provide detailed indications on how to better plan beach maintenance activities. The presented methodology and the proposed results can therefore be used as a basis for improving the collaboration between coastal scientists and managers to solve beach erosion problems, in a location where data are seldom.
