Assessment of Coastal Vulnerability Based on the Use of Integrated Low-Cost Monitoring Approach and Beach Modelling: Two Italian Study

Abstract

The use of video-monitoring techniques is significantly increased due to the diffusion of high-resolution cameras at relatively low-costs and they are largely used to estimate the shoreline evolution and wave run-up, as important coastal state indicators to be monitored and predicted for the assessment of flooding and erosion risks. In this work, we present an integrated approach based on the results from the low-cost video monitoring systems and the numerical modeling chain by means of SWAN and XBeach to accurately simulate and predict the swash zone processes.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/nLGNneJzmIU

Low-Cost Sensors for Monitoring Coastal Climate Hazards: A Systematic Review and Meta-Analysis

“…Shorelines derived from VMS also form the basis for developing coastal state indicators (CSIs; [ 157 ]. Timex images from VMS [ 38 , 39 , 43 , 44 , 45 , 47 , 53 , 54 ] are used to detect shoreline position based on algorithms that can discriminate the intensity variability of the image at the land–water interface [ 32 ] such as semi-automatic and automatic image segmentation algorithms [ 53 , 54 , 158 , 159 ]. These VMS derived shorelines are not only used to measure shoreline changes but also the intertidal topography [ 38 , 53 ] based on the methodology developed by [ 160 ].…”

“…Validation with reference instruments has yielded an acceptable accuracy range [ 26 , 123 , 124 ] that helped establish the potential of these instruments for nearshore wave monitoring, although [ 123 ] states that off-the-shelf-GPS position receivers may not always yield the high data quality of the high-end Datawell wave rider buoys. VMS, too, has been utilised to study nearshore processes such as wave run-up [ 38 , 43 , 44 , 45 ] as described by [ 32 ]; however, no validation was provided. Finally, Ref.…”
