POWRE: A LIDAR Study of Hatteras and Ocracoke Islands Between 1996 and 1998

PI正在完成光探测和测距(LIDAR)培训，并利用哈特拉斯和奥克拉科克障碍岛海岸线的激光雷达数据启动对障碍岛动力学的研究。PI正在使用1996年、1997年和1998年的激光雷达地形数据来量化沿美国东部屏障岛系统的一部分的严重风暴影响。她将1)量化有风暴和无风暴期间每年的海岸线位置和变化，2)量化沿屏障岛屿和跨屏障岛屿侵蚀和淤积的物质的体积，3)评估在1930年‘S和1940年’S期间被栅栏和植被严重加固的岛屿屏障岛响应的变化，以及4)量化风暴年和非风暴年海滩尖端的长度和位置的变化。

The PI is completing Light Detection And Ranging (LIDAR) training, and initiating research on barrier island dynamics using LIDAR data from the coastline of Hatteras and Ocracoke barrier islands. The PI is using LIDAR topographic data from 1996, 1997 and 1998 to quantify severe storm impact along a portion of the eastern US barrier island system. She will 1) quantify shoreline position and change on an annual basis during intervals with and without storms, 2) quantify the volume of material eroded and accreted both along and across the barrier islands, 3) assess the variation in barrier island response of sections of the island that were heavily stabilized by fences and vegetation during the 1930's and 1940's, and 4) quantify the change in length and position of beach cusps during storm and non-storm years.
