LA_NOURISH - Spatial Extents of Beach Nourishment Along the Louisiana 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.

Trembanis and Pilkey (1998) prepared a summary of identifiable beach nourishment projects in the Gulf Coast region that had been conducted before 1996. 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.

海岸稳定工程可显著影响海岸线变化速率。其中，海滩养护（Beach Nourishment）会使观测到的海岸线变化速率偏向淤积或稳定状态，即便未实施养护的天然海滩本应处于侵蚀状态。
Trembanis与Pilkey（1998）汇总整理了1996年前墨西哥湾沿岸地区已开展的可识别海滩养护项目清单。研究团队借助这些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处收集补充的海滩养护相关信息，最终整合所有记录生成了用于展示该州内所有海滩养护项目空间范围的GIS图层。
