Coastal flooding in America has caused large-scale changes with many communities seeing increased flooding. Flooded communities, collapsed bridges, and obstructed roads are some of the lasting effects that can be devasting ...
-
(2016-04-08)This dissertation evaluated how spatial patterns of pervious land cover moderate flood impacts in urban areas during an extreme rainfall event. First, it presented criteria to characterize hydrologic functions of natural ...
-
(2011-08-08)A tall tower flux measurement setup was established in metropolitan Houston, Texas, to measure trace gas fluxes from both anthropogenic and biogenic emission sources in the urban surface layer. We describe a new relaxed ...
-
(2014-11-21)Currently, recovery efforts for the federally endangered red-cockaded woodpecker (RCW; Picoides borealis) primarily occur on public lands throughout the Southeast, where proven management practices ensure availability of ...
-
Geography of Historical Racial-Ethnic Segregation: Comparing Charleston, SC and Buffalo, NY in 1940 Spatial distribution patterns of social groups can be studied through the use of digital “boundary” files, or “shapefiles,” and data from the U.S. Census. Shapefiles are readily available for recent decades but they are ...
-
(2009-06-02)This thesis develops a GIS-based Bayesian approach for area-wide traffic crash analysis. Five years of crash data from Houston, Texas, are analyzed using a geographic information system (GIS), and spatial-temporal patterns ...
-
(Texas A&M University, 2006-10-30)Rio Grande wild turkey (RGWT) abundance in portions of the Edwards Plateau has declined steadily since the late 1970s as compared to other areas of the Edwards Plateau where populations have exhibited no trend. The reasons ...
-
(2012-11-26)The task of preserving and improving infrastructure systems is becoming extremely challenging because these systems are decaying due to aging and over utilization, have limited funding, and are complex in nature (geographically ...
-
(Texas A&M University, 2005-11-01)This study investigated the use of high resolution satellite imagery in research involving habitat selection, and movement patterns of white-tailed deer and cattle in a semi-arid landscape. Vegetation classification was ...
-
(ALA Map and Geography Round Table, 2005-01-31)For 20 years, David Rumsey assembled a collection of more than 150,000 historical maps of the Americas and the world. Motivated by a desire to make his private map collection a free public resource, Rumsey then created an ...
-
(2022-12-09)The research I report in this study draws on previously unavailable detailed restricted Census microdata and employs recent innovations in methods of segregation analysis to examine and clarify the social dynamics that ...
-
(2010-07-14)The sustainability of the Texas agricultural and timber sectors is measured using the ratio of human appropriation of net primary productivity (HANPP) to available net primary productivity (NPP) on a county-by-county basis ...
-
(2012-02-14)This study explored the relationship between increased proportions of imperviousness in a watershed on surface water quality and examined the effectiveness of using remote sensing to systematically and accurately determine ...
-
(2018-05-05)Only three aquifer storage and recovery systems (ASR) currently operate in Texas, and less than 2% of Texas’ future water supplies are expected to come from ASR. Texas water utilities have avoided implementing ASR due to ...
-
(2012-10-19)Coastal storm surges from hurricanes are one of the most costly natural disasters in the United States (US). Current research arguably indicates a mean sea-level (MSL) increase due to global warming, as well as an increase ...
-
(Texas A&M University, 2004-09-30)This thesis presents the development of a hydrologic model in the vector environment. Establishing spatial relationship between flow elements is the key for flow routing techniques. Such a relationship is called hydrologic ...
-
(2009-06-02)Natural and human-induced environmental changes have been altering the earth's surface and hydrological processes, and thus directly contribute to the severity of flood hazards. To understand these changes and their impacts, ...
-
(Texas Water Resources Institute, 2011-04)This report summarizes our evaluation of the potential of Landsat satellite multi-spectral land cover imagery for GIS-based urbanization analysis in irrigation districts. Three image scenes of ETM+ (2003) and TM (1993) ...
-
(Texas A&M University, 2007-04-25)This thesis presents a methodology for conducting logistic regression modeling of trip and household information obtained from household travel surveys and vehicle trip information obtained from global positioning systems ...
-
(Texas A&M University, 2005-02-17)This study examines the relationship between the developing landscape and the water flowing through it. The study area was an 86 sq. mi. watershed located in the coastal plains in Harris County, Texas. Daily streamflow ...
