SBR-9625709 Gregory Stone Louisiana State University This Small Grant for Exploratory Research (SGER) supports a one-year program to measure the post-storm recovery of a particular barrier island on the north Florida (panhandle) coast, after Hurricane Opal (a Category 3 storm on the Saffir Simpson Scale, with sustained winds of 130 mph). The measurements include: beachfront core samples taken at 500-meter intervals monthly; monthly sediment samples at a grid that includes a cross-section of five zones from step and mid-tide levels to upper-beach, new foredunes, and backbarrier areas; daily meteorological data; and daily wind direction and speed. The most important of the process questions to be asked are the roles and the interactions of wind, wave, and current transport processes in the sediment erosion and deposition processes in post-storm recovery. The National Parks Service will close the area to human activity for at least one year, so the investigator will be able to observe the natural process of regeneration Our understanding of the initial phases of island recovery after severe storms is based primarily on supposition, largely governed by our interpretation of the day-to-day dynamics of barrier islands. This research will generate high-quality field data, culminating in the development of a heuristic model designed to identify and elucidate the importance of separate yet interrelated post-storm recovery processes and the morphological features of the site.

路易斯安那州立大学 探索性研究（SGER）支持一项为期一年的计划，以测量飓风Opal（Saffir Simpson等级的3级风暴，持续风速为130英里/小时）后，北佛罗里达（狭长地带）海岸的一个特定屏障岛屿的风暴后恢复。 测量包括：每月以500米的间隔采集海滨核心样本;每月在网格中采集沉积物样本，其中包括从阶梯和中潮水位到上海滩、新前沙丘和后屏障区域的五个区域的横截面;每日气象数据;以及每日风向和风速。 要问的最重要的过程问题是风暴后恢复的沉积物侵蚀和沉积过程中的风，波浪和电流传输过程的作用和相互作用。 国家公园管理局将关闭该地区至少一年的人类活动，因此调查人员将能够观察自然的再生过程 我们对严重风暴后岛屿恢复的初始阶段的理解主要基于假设，主要受我们对屏障岛屿日常动态的解释所支配。 这项研究将产生高质量的现场数据，最终开发一个启发式模型，旨在确定和阐明独立但相互关联的风暴后恢复过程和现场形态特征的重要性。
