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，并开始使用Hatteras和Ocracoke屏障岛屿海岸线的LIDAR数据进行屏障岛屿动态研究。 PI正在使用1996年、1997年和1998年的激光雷达地形数据来量化美国东部屏障岛系统沿着的严重风暴影响。 她将1）在有风暴和无风暴的间隔期间，量化海岸线位置和每年的变化，2）量化沿着和跨越屏障岛的侵蚀和增生物质的体积，3）评估20世纪30年代和40年代期间被围栏和植被严重稳定的岛屿部分屏障岛响应的变化，以及4）量化风暴和非风暴年份期间海滩尖点长度和位置的变化。

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.
