Dr. Quintanilla explains to us the policies and procedures she followed to prepare the university and students for the possibility of Hurricane Harvey making landfall in Corpus Christi, Texas. This project was turned into the Hurricane Harvey Oral History Collection, which explores, uncovers, and highlights the lives of residents from South Texas who experienced Hurricane Harvey. The collection was created in an effort to ensure that the memories of those affected by the hurricane not be lose, and to augment the Mary and Jeff Bell Library’s Special Collections and Archives Department records.

  • Appendix 8 Hazard Analysis
    Appendix 8 Hazard Analysis Introduction This appendix includes several components. First is an overall discussion of the Hazard Analysis modeling effort, describing the surge (ADCIRC) and wave (WAM, STWAVE) modeling. That first section is followed by a subsidiary section labeled Appendix 8-1 that defines the many acronyms used in the modeling discussion. This is followed by a major section labeled Appendix 8-2 consisting of the Whitepaper of Donald T. Resio, ERDC-CHL, which forms the basis of the storm statistics and JPM methods discussed in the main body of the report. Owing to its prominence in the discussion, it has, for convenience, been referred to as R2007. Note that R2007, itself, includes several appendices; these are identified as Appendices A-G within Appendix 8-2. Finally, a discussion of the rainfall model is included here as Appendix 8-3. Hazard Analysis The hazard analysis required for the risk assessment was based upon the hurricane modeling conducted by a team of Corps of Engineers, FEMA, NOAA, private sector and academic researchers working toward the definition of a new system for estimating hurricane surges and waves. Following is a discussion of the processes used by this team and the steps taken by the risk team to incorporate the results into the risk analysis. The hurricane hazard definition required as input to the risk analysis involved several steps: 1. Selection of the methodology to be used for estimating surges and waves 2. Determination of hurricane probabilities 3. Production of the ADCIRC grid models for the different HPS configurations. 4. Production of the computer system for development of the large number of hydrographs required by the risk model.

  • Ch 5. the Atmospheric Environment Observed at Big Bend National
    Final Report — September 2004 5. THE ATMOSPHERIC ENVIRONMENT OBSERVED AT BIG BEND NATIONAL PARK DURING THE BRAVO STUDY The BRAVO Study intensively researched the properties of the particulate matter, atmospheric optics, meteorology, and air pollutant emissions of the study area during July through October 1999. The study also explored transport and diffusion by injecting perfluorocarbon tracers into the atmosphere at specific locations. Findings produced by these multiple experiments concerning the environment around Big Bend National Park and throughout the study area are summarized in this chapter. Some of these findings were carried into the source attribution analyses that are described in Chapters 10 and 11, while others advanced scientific understanding for future application. More detail on many of these studies and their results is provided in published papers and reports that are cited in the text; some of the reports are in the Appendix. 5.1 Particulate Matter Characterization by the Routine Measurement Network As described in Section 3.3, the BRAVO Study included an extensive network of particulate matter samplers that routinely collected 24-hour and 6-hour samples over the four-month study period. This section summarizes findings derived from the routine measurements concerning the temporal and spatial characteristics of the study area particulate matter and its composition. 5.1.1 Particulate Matter Temporal and Spatial Characteristics Evaluation of BRAVO Study particulate matter sample composition and temporal variation found similar behavior at groups of adjacent sampling sites in the study domain. The map in Figure 5-1 shows the grouping of sampling sites that this evaluation suggested. To provide a manageable description of the study period aerosol, concentration measurements at sites within each group were averaged together.

  • A Classification Scheme for Landfalling Tropical Cyclones
    A CLASSIFICATION SCHEME FOR LANDFALLING TROPICAL CYCLONES BASED ON PRECIPITATION VARIABLES DERIVED FROM GIS AND GROUND RADAR ANALYSIS by IAN J. COMSTOCK JASON C. SENKBEIL, COMMITTEE CHAIR DAVID M. BROMMER JOE WEBER P. GRADY DIXON A THESIS Submitted in partial fulfillment of the requirements for the degree Master of Science in the Department of Geography in the graduate school of The University of Alabama TUSCALOOSA, ALABAMA 2011 Copyright Ian J. Comstock 2011 ALL RIGHTS RESERVED ABSTRACT Landfalling tropical cyclones present a multitude of hazards that threaten life and property to coastal and inland communities. These hazards are most commonly categorized by the Saffir-Simpson Hurricane Potential Disaster Scale. Currently, there is not a system or scale that categorizes tropical cyclones by precipitation and flooding, which is the primary cause of fatalities and property damage from landfalling tropical cyclones. This research compiles ground based radar data (Nexrad Level-III) in the U.S. and analyzes tropical cyclone precipitation data in a GIS platform. Twenty-six landfalling tropical cyclones from 1995 to 2008 are included in this research where they were classified using Cluster Analysis. Precipitation and storm variables used in classification include: rain shield area, convective precipitation area, rain shield decay, and storm forward speed. Results indicate six distinct groups of tropical cyclones based on these variables. ii ACKNOWLEDGEMENTS I would like to thank the faculty members I have been working with over the last year and a half on this project. I was able to present different aspects of this thesis at various conferences and for this I would like to thank Jason Senkbeil for keeping me ambitious and for his patience through the many hours spent deliberating over the enormous amounts of data generated from this research.

    2012 MONTHLY WEATHER REVIEW VOLUME 127 Atlantic Hurricane Season of 1997 EDWARD N. RAPPAPORT Tropical Prediction Center, National Hurricane Center, NOAA/NWS, Miami, Florida (Manuscript received 12 June 1998, in ®nal form 5 October 1998) ABSTRACT The 1997 Atlantic hurricane season is summarized and the year's tropical storms, hurricanes, and one sub- tropical storm are described. The tropical cyclones were relatively few in number, short lived, and weak compared to long-term climatology. Most systems originated outside the deep Tropics. Hurricane Danny was the only system to make landfall. It produced rainfall totals to near 1 m in southern Alabama and is blamed for ®ve deaths. Hurricane Erika was responsible for the season's two other fatalities, in the coastal waters of Puerto Rico. 1.

Toulouse School of Graduate Studies Pettibon, Gregory Jason, The Development and Economic Impacts to the State of Texas from the Construction of Interstate 69. Master of Science (Applied Economics), December 2002, 60 pp., 16 tables. Regional population growth and increasing trade with Mexico are creating severe traffic congestion along Interstate 35 and at the Laredo bridge crossings. The construction of a new Interstate Highway 69 has been offered as one solution to this problem. This analysis examines the economic impacts of building Interstate 69 and its potential impact on job creation in the counties along its projected path. Using the IMPLAN input-output modeling system, construction of Interstate 69 will support $4.2 billion in economic activity in the counties through which it will pass. More importantly, based on an analysis of Interstate 27 in west Texas, it can be projected that Interstate 69 will spur a 2% gain in regional employment above any usual economic growth.
