Abstract

abstract:National seashores are cherished public lands with rich environmental, cultural, and historic resources. The Cape Hatteras National Seashore is one such coastal asset that is both bountiful yet vulnerable, with historic lighthouses, critical habitats, and recreational amenities alike facing threats of sea-level rise and continual storm and climate change impacts. Over 3 million visitors to the Seashore in 2021 set an annual visitation record. Historic resources such as the Bodie Island Lighthouse and Ocracoke Lighthouse are among the most visited sites, yet these assets are also among those most vulnerable to flooding, compromised structural integrity, and reduced accessibility. Future challenges to the protection and management of such resources are already being felt in the form of storms, extreme rainfall, and recurrent compound flooding. Such threats are also coincident with increasing visitation and recreational demand. This paper examines the science-based data that are being collected and management efforts underway to inform future planning, intervention, or adaptation to sea-level rise and barrier island evolution. The paper identifies the opportunities for mitigation and adaptation as well as potential environmental tipping points and limits to resilience by assessing the frequency and magnitude of flooding events and shoreline change.

美国北卡罗来纳州哈特拉斯角国家海岸的恢复力和管理海岸科学

国家海岸是珍贵的公共土地，拥有丰富的环境、文化和历史资源。哈特拉斯角国家海岸(Cape Hatteras National Seashore)就是这样一处既丰富又脆弱的海岸资产，拥有历史悠久的灯塔、重要的栖息地和娱乐设施，这些设施都面临着海平面上升、持续风暴和气候变化影响的威胁。2021年，超过300万游客来到海滨，创下了年度游客记录。Bodie岛灯塔和Ocracoke灯塔等历史资源是访问量最大的景点之一，但这些资产也最容易受到洪水的影响，结构完整性受损，可达性降低。未来对这些资源的保护和管理的挑战已经以风暴、极端降雨和经常性复合洪水的形式出现。这些威胁也与不断增加的游客和娱乐需求同时发生。本文考察了正在收集的基于科学的数据和正在进行的管理工作，为未来的规划、干预或适应海平面上升和堰洲岛的演变提供信息。该文件通过评估洪水事件和海岸线变化的频率和规模，确定了缓解和适应的机会，以及潜在的环境临界点和复原力的限制。
