Kiawah Conservancy analysis of unvegetated-vegetated marsh ratios [ UVVR ] within the Kiawah River Watershed within 2.5-acre hydrologic watershed units ( Ganju et al ., 2020 ). Vegetative coverage was determined using Iso Cluster Unsupervised Classifications on high-resolution aerial imagery and digital elevation models . Generated clusters were visually analyzed using USDA NAIP imagery from 2021 and high resolution ( 2 ”) imagery from 2022 . ( Above ) Generated UVVR values for tidal wetlands . ( Below ) Net sediment budget ( Qb ) generated from UVVR values for each marsh section ( Ganju et al ., 2017 ; Ganju et al ., 2020 ).
