### Application of the Implemented Methodology to the 5-7 July 2020 Meteo-Marine Event  
In Figure 9, we showed the surface and vertically averaged turbidity continuously measured by the instrumental network during the 5-7 July 2020 event. Figure 17 provides the satellite-derived map of the synoptic distribution of turbidity in the inlet area and the time series of turbidity along the water column of the TRP and SN channels, obtained from the conversion of backscatter of the two bottom-mounted ADCPs.  
Figure 16: (**Left**) panels: scatter plot of measured turbidity versus turbidity estimated from the conversion of backscatter from bottom-mounted ADCPs for TRP and SN stations. (**Right**) panels: plots of the measured turbidity versus error ratio for TRP and SN stations. Grey solid lines are the 1:1 lines; the red dashed line represents the error ratio equal to 1. The black dots represent 4-beam averaged turbidity from ADCP data. The error bars in all plots represent the range of the four ADCP beams estimates (min and max values).  
The scene represented in the turbidity map shows the surficial patterns of suspended sediment and enables the inferring of information on the transport processes at different spatial scales in these typical wind conditions. The intense sediment resuspension on the coast caused by the action of waves on the shoreface is particularly evident. One interesting feature is the clear-cut boundary of the area, where materials resuspended from the coast were transported by longshore current, which seems to imply a limited exchange between this coastal belt (approximately 1 km) and the open sea. Close to the inlet mouth, the flood tidal current drags this turbid belt into the main channel from which the particulate is distributed into the lagoon channel network. This confirms and supports the interpretation of the continuous dataset and emphasizes the important role of storm-driven sediment supply on the morphodynamics of wetlands, as also discussed by [21].  
During the satellite overpass and image acquisition, the TRP channel received the larger fraction of suspended sediments at the surface, while the SN channel had lower turbidity values. This can be related to a peculiar hydrodynamic condition originated by a test of the MoSE barriers, which determined the partial closure of the SN channel in the time interval around image acquisition. The sheltered area at south-west of the inlet was characterized by a markedly lower range of turbidity. Yet, in this area, the patterns of turbidity highlighted the trend of currents around the jetty and the artificial breakwater.  
The panels on both sides of the map represent the time series of turbidity along the water column of the TRP and SN channels during the meteo-marine event. The intense pulse of suspended material caused by the wind event overlapped to the regular modulation of turbidity values along the column by the tidal currents. For the SN section, the surface values were consistent to those of the turbidity map and fixed turbidimeter at the time of overpass, whereas TRP values were underestimates. This is likely due to the position of the bottom-mounted ADCP, which was slightly marginal in respect to the flow line.
