*2.5. Sediment Volume*

To analyze the shoreline transformational behavior, SANDS Assessment Management software can be used to quantify the volume of sediments eroded and accreted from shorelines [12]. In the volumetric analysis of the North Captiva coastline, SANDS was used to quantify these sediment changes. This analysis was carried out from 2004 Post Hurricane Charley through 2018. The beach volume change, measured in cubic meters, was estimated for the island segment delimited by transects referenced by neighboring R-monuments between the years in the study area [11]. For the breached location, towards the southern end, additional transects were established for an increased resolution in volumetric analysis.
