Estimated storm surge impacts and marginal values of changes in wetland continuity (WL) and roughness (WR).

WL is represented by the wetland/water ratio ranging from open water (WL = 0) to solid marsh (WL = 1).WR is represented by Manning’s n for bottom friction caused by degree of wetland vegetation ranging from no vegetation (WR = 0.02) to high density vegetation (WR = 0.045).Mean maximum surge level (S) is 2.302 m.Mean wetland/water ratio (WL) is 0.408.Mean Manning’s n (WR) is 0.032.Mean transect segment length (x) is 5,961 m.Based on Tables S1–S3.WL以湿地水占比（wetland/water ratio）表征，该比值的取值范围对应开阔水域状态（此时WL=0）至实心沼泽状态（此时WL=1）。WR以曼宁糙率系数（Manning’s n）表征，该系数用于描述湿地植被覆盖程度引发的底床摩擦效应，其取值范围为无植被覆盖（WR=0.02）至高密度植被覆盖（WR=0.045）。平均最大风暴潮位（S）为2.302米。平均湿地水占比（WL）为0.408。平均曼宁糙率系数（WR）为0.032。平均断面段长度（x）为5961米。本数据集基于补充表S1至S3。
