SC_NOURISH - Spatial Extents of Beach Nourishment Along the South Carolina Atlantic Coast

Attempts to stabilize the shore can greatly influence rates of shoreline change. Beach nourishment in particular will bias rates of observed shoreline change toward accretion or stability, even though the natural beach, in the absence of nourishment, would be eroding.

Pilkey and Clayton (1990) prepared a summary of identifiable beach nourishment projects in the Atlantic Coast region. Those records were used to identify shoreline segments that had been influenced by beach nourishment. Supplemental information regarding beach nourishment was collected from agencies familiar with nourishment projects in the State. All records were compiled to create a GIS layer depicting the spatial extents of nourishment projects within the State.

海岸加固举措可显著影响海岸线变化速率。其中，海滩养护（beach nourishment）会使观测得到的海岸线变化速率偏向淤积或稳定状态，即便未实施养护措施的天然海滩本应处于侵蚀状态。
Pilkey与Clayton（1990）编制了大西洋海岸区域可识别海滩养护项目的汇总资料。研究团队依托上述记录，识别出受海滩养护影响的海岸线区段。随后从该州内熟悉海滩养护项目的相关机构收集了补充信息。最终整合全部记录，生成了用于表征该州境内海滩养护项目空间范围的GIS图层。
