In the context of climate change, future coastal flooding will become increasingly impactful, driven primarily by sea level rise and intensification extreme precipitation events along coastlines, rather than changes in wind regimes, wave dynamics, or hydrodynamic circulation (IPCC, 2021; Vousdoukas et al., 2018). Due to vast geomorphological diversity coastlines varying exposure assets at risk, advanced tools are necessary for precise risk assessments, particularly urban areas human...

This study presents an integrated modeling framework designed to bridge scales from regional urban, enabling a detailed assessment of the impacts future climate scenarios on three European coastal cities: Massa (Italy) and Vilanova (Spain) in Mediterranean, Oarsoaldea Atlantic. Conducted as part SCORE EU Project (Smart Control Climate Resilience Coastal Cities), employs novel, non-standard downscaling approach translate large-scale atmospheric outputs EURO-CORDEX model ALADIN63...

Urban seismic networks are considered very useful tools for the management of emergencies. In this work, a study first urban network in central Italy is presented. The network, built using MEMS sensors, was implemented district Camerino, one cities with greatest vulnerability. technological choices adopted developing system as well algorithms shown context their application to event recorded by innovative monitoring infrastructure. This because it implements distributed computing and...

In this paper, we have studied the sources of error a low-cost 3-axis MEMS accelerometer by means Power Spectral Density and Allan Variance techniques. These techniques were applied to signals acquired from ten identical devices characterize variability sensor produced same manufacturer. Our analysis showed as identically somehow variable behavior in particular at low frequency. It is therefore paramount importance before their use Inertial Navigation or Earthquakes Monitoring System,...

An effective reduction of seismic risk can implement through a multiscale approach to the earthquakes monitoring. Devoted monitoring network are essential cope with emergency in urban areas, assess damage scenarios, which useful for preservation strategic functions and services improve community resilience earthquakes. The National Earthquake Observatory, Italian Institute Geophysics Volcanology (ONT-INGV, Italy), has been recently involved several projects devoted by means implementation...

Artificial beach nourishment can significantly modify original colour, altering an important component of the coastal landscape; this produce deleterious environmental effects and potentially induce controversies among stakeholders, leading even to litigation. This paper reviews some these impacts, discusses chromatic compatibility borrow sediments, proposes techniques assess it. Further, it evaluates preference users towards different sand colours through 320 interviews held at natural...

We introduce the realization of first European real-time urban seismic network based on Micro Electro-Mechanical Systems (MEMS) technology. The project is called Monitoring Earthquake through MEMS Sensors and encompass installation about 100 station in municipality Acireale (Sicily, Italy). stations, specifically designed assembled, are equipped with a triaxial accelerometer, gyroscope GPS. In this paper we present characteristics network. main objective rapid, post-earthquake disaster...

Detection of the Earth’s magnetic field anomalies is basis many types studies in earth sciences and archaeology. These surveys require different ways to carry out measures but they have common that can be very tiring or expensive. There are now several lightweight commercially available sensors allow light-UAVs equipped perform airborne measurements for a wide range scenarios. In this work, realization functioning an magnetometer prototype were presented discussed. Tests validation...

Abstract. In this paper we simulate unmanned aerial vehicle (UAV) recognition after a possible case of diffuse damage seismic event in the town Acireale (Sicily, Italy). Given set sites (84 relevant buildings) and range UAV, are able to find number vehicles employ shortest survey path. The problem finding path is an operational research called routing (VRP). which has solution that known be computationally time-consuming. We used simulated annealing (SA) heuristic, provide stable solutions...

A technological system capable of automatically producing damage scenarios at an urban scale, as soon earthquake occurs, can help the decision-makers in planning first post-disaster response, i.e., to prioritize field activities for checking damage, making a building safe, and supporting rescue recovery. This be even more useful when it works on densely populated areas, well historic centers. In paper, we propose processing chain GIS platform generate post-earthquake scenarios, which are...

Severe erosion has been affecting the Ombrone river delta apex since second half of 19 th Century and is currently expanding gradually to adjacent beaches. Main causes this process include coastal marsh reclamation, land-use changes within watershed, dam construction, bed quarrying. In addition, area subsiding at an average rate approximately 10 mm/yr. As a result, mouth underwent shoreline retreat over 1100 m in past 130 years, reaches peak m/yr. During recent decades, Maremma Regional Park...
