Available in PDF, EPUB and Kindle. Book excerpt: Hurricanes are well known for producing catastrophic devastation to both natural and human environments along the northern Gulf of Mexico coastline. Hurricane Ike made landfall on the eastern tip of Galveston Island, Texas, on 13 September 2008, and the region in the right-front quadrant of the storm experienced catastrophic storm surge flooding. This study investigates spatial variations in sediment distribution on McFaddin National Wildlife Refuge, which is located in the geographic region that was impacted by the right-front quadrant of Hurricane Ike. Fieldwork conducted in summer 2017 and summer 2018 involved digging shallow pits on four transects between Sabine Pass, Texas, and High Island, Texas. Eight pit sites were established on Transect 1, the easternmost transect, and six pit sites each were established on Transects 2, 3, and 4, with Transect 4 located farthest west. All four transects extend 880-1630 meters, with pit sites beginning near the coastline and extending landward. Elevations were measured at each pit site along all four transects using a telescopic level and stadia rod. Results obtained in the field indicate that the Hurricane Ike sediment deposit has been found on all four transects, and that the deposits decrease in thickness moving landward along each transect. On Transect 1, at Pit Site 1, the thickness of the Hurricane Ike deposit was 61 centimeters; this same deposit gradually tapers down to a thickness of 4 centimeters at Pit Site 8. On Transect 4, Pit Site 1 had a sediment thickness of 53 centimeters, whereas at Pit Site 6 the deposit was 5 centimeters thick. Additionally, there is evidence that sedimentation has been impacted by the presence of man-made levees that lie perpendicular to the Gulf Coast at Transects 2, 3, and 4. Furthermore, the observational results of this study were used in Regression Analyses to model hurricane storm surge sediment deposit thickness based on pit site distance inland, pit site elevation, and distance from the landfall of Hurricane Ike. Moreover, Analysis of Variance revealed whether distance inland, distance from landfall location, and the interaction between distance inland and distance from landfall location had any significant effect on storm surge deposit thickness. Actual sediment deposit thicknesses measured in the field were compared to the Regression and Analysis of Variance results. Results show that the Power Law Curve from the Regression Analyses was the most robust predictor of pit site sediment thickness based on distance inland, with an R2 value of 0.538. Additionally, the Regression and Analysis of Variance results revealed that transect distance from the landfall location of Hurricane Ike was the only independent variable that could not predict or explain storm surge deposit thickness. The goal of this study was to discover spatial variations in storm surge sedimentation in the geographic region impacted by the right-front quadrant of Hurricane Ike. The findings of this study provide improved understanding of the spatial relationship between storm surge sedimentation and storm surge heights, valuable knowledge about the sedimentary response of coastal marshes subject to storm surge deposition, and useful guidance to public policy aimed at combating the effects of sea-level rise on coastal marshes along the northern Gulf of Mexico coastline.

This book was released on 2016 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study uses the storm surge sediment beds deposited by Hurricanes Audrey (1957), Carla (1961), Rita (2005) and Ike (2008) to investigate spatial and temporal changes in sedimentation rates on the McFaddin National Wildlife Refuge in Southeast Texas. Fourteen sediment cores were collected along a transect extending from 90 to 1230 meters inland from the Gulf Coast. Storm-surge-deposited sediment beds were identified by texture, organic content, carbonate content, the presence of marine microfossils, and Cesium-137 dating. The hurricane-derived sediment beds are marker horizons that facilitate assessment of marsh sedimentation rates from nearshore to inland locations as well as over decadal to annual timescales. Near the shore, on a Hurricane Ike washover fan, where hurricane-derived sedimentation has increased elevation by up to 0.68 m since 2005, there was no measurable marsh sedimentation in the period 2008-2014. Farther inland, at lower elevations, sedimentation for the period 2008-2014 averaged 0.36 cm per year. The reduction in sedimentation in the period 2008-2014 on the nearshore part of the marsh is likely due to reduced flooding in response to increased elevation from hurricane storm surge sediment deposition. These results provide valuable knowledge about the sedimentary response of coastal marshes subject to storm surge deposition and useful guidance to public policy aimed at combating the effects of sea level rise on coastal marshes along the Gulf of Mexico.

Committee on Long-Term Coastal Zone Dynamics: Interactions and Feedbacks Between Natural and Human Processes Along the U.S. Gulf Coast and published by . This book was released on 2018 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The U.S. Gulf Coast provides a valuable setting to study deeply connected natural and human interactions and feedbacks that have led to a complex, interconnected coastal system. The physical landscape in the region has changed significantly due to broad-scale, long-term processes such as coastal subsidence and river sediment deposition as well as short-term episodic events such as hurricanes. Modifications from human activities, including building levees and canals and constructing buildings and roads, have left their own imprint on the natural landscape. This coupled natural-human coastal system and the individual aspects within it (physical, ecological, and human) are under increased pressure from accelerating environmental stressors such as sea level rise, intensifying hurricanes, and continued population increase with its accompanying coastal development. Promoting the resilience and maintaining the habitability of the Gulf Coast into the future will need improved understanding of the coupled natural-human coastal system, as well as effective sharing of this understanding in support of decision-making and policies. Understanding the Long-term Evolution of the Coupled Natural-Human Coastal System presents a research agenda meant to enable a better understanding of the multiple and interconnected factors that influence long-term processes along the Gulf Coast. This report identifies scientific and technical gaps in understanding the interactions and feedbacks between human and natural processes, defines essential components of a research and development program in response to the identified gaps, and develops priorities for critical areas of research"--Publisher's description

Available in PDF, EPUB and Kindle. Book excerpt: Katrina's arrival on the Gulf Coast was a long time in coming. But it was assured. Since 1965, when Hurricane Betsy struck New Orleans, breached a levee, and flooded part of the city, everyone was waiting and talking about when the Big One would strike and do even more damage. Katrina was that hurricane, predictedand imagined before she struck, but so much worse in her reality. Holding Back the Sea is about the consequences of ignoring the warning signs that nature provides and the struggle to convince the rest of the country that South Louisiana lay in the path of destruction. The signs were not subtle; there were Hurricanes Andrew in 1992, George and Mitch in 1998, and Ivan in 2004, among others. At one time or another in their journeys north, they all threatened New Orleans. Some had headed right for the city before veering to the east and west, sparing the Big Easy and reinforcing the nickname. But the Big Easy ended -- at least in reputation -- on August 29, 2005, when the Big One came ashore as Katrina.

Book excerpt: Hurricane Frederic made landfall near Pascagoula, Mississippi at midnight, September 13, 1979. At the time of landfall, the central pressure had dropped to 946 mb; onshore winds in excess of 200 km/hr were lashing the Alabama coastline, and the open coast storm tide peaked at 365 cm at Gulf Shores, Alabama. Vertical aerial photography obtained in 1976 and again 9 days after Frederic made landfall, combined with multiple reconnaissance overflights and ground surveys by the authors, provided the data base for determination of shoreline erosion and the deposition of hurricane scour and sedimentary deposits. Erosion of the Gulf beach at Dauphin Island proved to follow a predictable pattern, controlled by nearshore bathymetry, whereas retreat of the shoreline of the Mississippi Sound margin was an unexpected occurrence. Apparently, this retreat was due to a hydraulic jump as washover currents entered the deep water of Mississippi Sound. Large-scale sediment redistribution on Dauphin Island proper was a consequence of the storm surge flood. The ebb surge, however, was responsible for the reopening of three inlets across Little Dauphin Island. The wave-induced property destruction on Dauphin Island was most intense immediately west of the area of high dunes. This segment of the island, the easternmost portion of the Holocene spit, has been breached twice in this century. During future storm events, breaching, or at the very least severe property destruction, in this area seems inevitable. A sensible land use plan for Dauphin Island should include a search for alternative, and potentially safer, areas for development.
