Hurricane Impact and Recovery on Coastal Island Geomorphology: Hurricane Opal, October 1995

9625709格雷戈里·斯通路易斯安那州立大学这笔小额探索性研究补助金支持一项为期一年的计划，以衡量飓风Opal(萨菲尔·辛普森等级的3级风暴，持续风速为每小时130英里)过后，佛罗里达州北部(狭长柄)海岸上特定屏障岛屿的风暴后恢复情况。这些测量包括：每月500米间隔采集的海滨岩心样本；每月网格处的沉积物样本，该网格包括从潮级和中潮水平到海滩上、新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、浪和流的输送过程在风暴后恢复的泥沙侵蚀和沉积过程中的作用和相互作用。国家公园管理局将在至少一年内关闭该地区，禁止人类活动，因此调查员将能够观察岛屿恢复的自然过程。我们对强风暴后岛屿恢复初始阶段的理解主要基于假设，很大程度上取决于我们对屏障岛屿日常动态的解释。这项研究将产生高质量的实地数据，最终形成一个启发式模型，旨在确定和阐明独立但相互关联的风暴后恢复过程的重要性以及场地的形态特征。

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.
