Transit Climate Change Adaptation Assessment Pilots for the Gulf
Coast Region
Duration: 2012-2013
Funding Agency: Federal Transportation Agency
Funding Amount: $146,000
PI: Linda Cherrington, TTI
Co-PI: Samuel Brody, Mathew Sandidge
Students/staff Employed: Russell Blessing, Alexandra Stiles
Abstract
Researchers will conduct a pilot for the Gulf Coast region
that provides adaptation strategies for three climate change
impacts--extreme heat, flooding, and high winds--on transit
agency assets, operations, maintenance, service, and the transit
agency constituency. Under current climate patterns, the Gulf
Coast region experiences heat waves, tropical storms and
hurricanes, high winds, and excessive downpours that can damage
transit assets and strain agency budgets. Researchers will
partner with transit agencies to evaluate existing plans and
procedures on mitigating the impacts of weather conditions on
the agency and develop effective adaptation strategies for
future events. Researchers will evaluate costs associated with
service disruption, capital, labor and maintenance costs to
maintain a state of good repair.
The study is a collaboration of the Texas Transportation
Institute (TTI), Texas A&M University’s Center for Texas Beaches
and Shores (CTBS), and the following three transit agencies:
· Hillsborough Area Region Transit (HART), Tampa, FL
· Island Transit, Galveston, TX
· Metropolitan Transit Authority of Harris County
(METRO), Houston, TX.

Examining the 100-year Floodplain as a Metric of Risk, Loss, and
Household Adjustment
Duration: 2011-2013
Funding Agency: National Science Foundation (NSF)
Funding Amount: $312,801
PI: Sam Brody; Co-PIs: Wesley E. Highfield,
Michael Lindell
Research Assistants: Russell Blessing, Joshua Gunn, Tak
Makino, Patrick Doty
Abstract
As flood losses continue to increase in the United States,
recent evidence suggests that the 100-year floodplain (the
primary marker of flood risk and mitigation) is neither accurate
nor sufficient in guiding communities and household decisions to
mitigate the adverse impacts of floods. The
inability of the floodplain designation to effectively capture
the likelihood of property loss has left potentially millions of
property owners unaware of the flood risk and has made it more
difficult for local decision makers to ensure community
development occurs in a resilient manner.
This project examines the effectives of the 100-year floodplain
in predicting property damages from floods and offers improved
criteria for assessing risk of inundation in low-lying coastal
areas. First, we will spatially examine the
record of insured property damage at the household level from
2000-2009 for a sample of coastal counties along the Gulf of
Mexico. Second, we will analyze statistical
models to predict insured property damage from floods using
proximity and built environment measures not traditionally used
to determine floodplain boundaries. Finally,
we will conduct a survey of households claiming losses both in
and out of the floodplain to understand the perceptions of flood
risks and motivations to mitigate their potential adverse
impacts.
This research will provide important
information to decision makers on how to implement more precise
strategies to reduce the costs of floods at the local level.
An improved understanding of flood risk will enable
localities to better protect themselves against loss of property
and lives in coastal areas. Research findings
will also help individuals living outside the floodplain, but
still at high risk for flood damages reduce the chances they
will experience devastating losses in the future. To
this end, a major part of the research project will be to
deliver findings that can be easily accessed and understood by
both public officials and local residents.
First, we will integrate our data on flood loss and areas of
risk an existing web-based GIS system that currently serves as a
technical assistance and outreach tool. Second, we
will work with local neighborhoods that have become hotspots of
flood loss to increase awareness of the problem and provide
options for reducing future loss. Third, we will bring results
from our study into the classroom as part of graduate and
undergraduate studies across two college campuses.
Through these approaches, we will ensure our research
findings assist local governments and individual households on
how to better reduce the negative impacts of coastal flooding in
the U.S.

Examining the Relationship Between Land Use Change, Wetland
Alteration, and Carbon Sequestration in the Gulf of Mexico
Duration: 2011-2013
Funding Agency: NASA
Funding Amount: $400,000
PI: Patrick Louchouarn
Co-PI: Anna Armitage, Wesley Highfield, Samuel Brody
Students/staff Employed: TBD
Abstract
Our proposed study will examine the relationship
between land use change, wetland vegetation shift/loss, and
carbon (C) sequestration on the coast of the Gulf of Mexico
(GOM). By combining field calibration with analysis of remote
sensing imagery to detect land cover change, we aim to better
understand the amount of carbon sequestration capacity lost from
the alteration of naturally occurring estuarine wetlands over
the last decade.

Dickinson Bayou On-Site Sewage Facilities (OSSF) Optimization
Model
Duration: Spring/Summer
2011
Funding Agency: TCEQ & Texas Coastal Watersheds Program
Funding Amount: $136,016
PI: Wesley Highfield
Co-PI: Samuel Brody
Students/staff Employed: Russell Blessing, Patrick Doty, Kevin
Crosby
Abstract
This project will assemble and incorporate data layers
into a Geographic Information System. Specifically, we will
assemble a geodatabase of pertinent spatial data for the
Dickinson Bayou watershed, including by not limited to soil
characteristics, hydrography, topography, wetlands, wastewater
treatment plants, and current OSSF locations. We will also
construct a GIS model that evaluates and prioritizes mitigation
of failing OSSF locations. This model will be based on the
location, density, and age of OSSF sites. These spatial OSSF
measures will be evaluated against the risk of water quality
deterioration using factors such as proximity to natural
drainage and wetlands, low soil infiltration rates, and
impervious surface.

Students/staff Employed: Himanshu Grover, Sri
Harsha , Rob Gatlin, Doug Wunneburger
Abstract
This project develops a coastal communities planning atlas
to help local jurisdictions in Texas understand the implications
of development decisions and plan appropriately for the future.
It will provide an easily accessible, graphically represented,
interactive database on environmental, hazard, and land use
related issues for local communities. Specifically, the project
will create an Internet-based spatial decision support system
that will allow users to identify and visualize critical
hotspots related to environmental degradation, natural hazard
risks, and significant changes in land use patterns. In
addition, users will be able to query data and create custom
maps based on multiple development scenarios. Communities will
be able to use this educational tool to guide future decisions
on growth in a sustainable manner such that the need for
economic development is balanced with priorities associated with
environmental protection and human health, safety, and welfare.
The system will also help address important research questions
related to where future growth will occur in the Texas coastal
zone, the impacts of this growth, and the usefulness of WebGIS
in facilitating sustainable planning.

Watershed Flooding and Adaptive Flood Management: An Integrative
Plan for Research, Teaching, and Learning
Duration: 2004 - 2010
Funding Agency: National Science Foundation (NSF) CAREER Award
Funding Amount: $515,500
PI: Sam Brody
Research Assoc: Wesley Highfield Employed: Anita Hollmann, Wes
Highfield, Jun Eun Kang,
Hee Ju Kim
Abstract
This research project addresses coastal flooding problems by
implementing an interactive research and educational program on
flood mitigation, sustainable watershed management, and policy
learning. It develops a framework for adaptive decision making
for coastal flood hazards by integrating research, education,
and information dissemination. The research component focuses on
the impacts of wetland development on coastal watershed flooding
and policy learning at the community level to mitigate the
adverse impacts of flood damage to the human and natural
environment. A two-phase longitudinal research design employs
both quantitative and qualitative analyses to investigate
flooding problems in Texas and Florida. Phase one will use
Geographic Information Systems (GIS) to examine the spatial
pattern of wetland development over a ten-year period and
correlate this development with coastal watershed flooding.
Phase two will identify thresholds of policy learning by
examining how communities adjust and adapt to repetitive
flooding. Both research phases will use multivariate analysis to
measure the effects of wetland development on flooding and the
effects of flooding on policy adjustment while controlling for
socioeconomic, biophysical, and other contextual factors.

Advancing the Resilience of Coastal Localities: Developing,
Implementing and Sustaining the Use of Coastal Resilience
Indicators
Duration: 2007 - 2010
Funding Agency: National Oceanographic Atmospheric
Administration (NOAA), Coastal Services Center (CSC)
Funding Amount: $299,922
PI: Walter Peacock
CO-PI: Sam Brody, Bill Seitz, Bill Merrell, Bob Harris
Students Employed: Josh Gunn
Abstract
Texas A&M University (TAMU), Texas A&M University at
Galveston (TAMUG), and the Houston Advanced Research Center
(HARC) are working together to develop a suite of Community
Resilience Indicators (CRIs) (Activity 1) and a comprehensive
strategy for not only gaining community support and input into
their development and implementing but also undertake future
training (Activity 2) in the use of CRIs to enhance coastal
community resilience along the Gulf Coast. Our project will also
be closely integrated with the University of New Orleans's
project in Louisiana. Drawing on two projects whose strengths
are complementary on indicator development and yet offer two
unique approaches for gaining and sustaining community
involvement will yield implementation strategies that include a
collaboratively-developed plan to develop and implement CRIs in
a range of community settings. The PIs will work closely with
the Coastal Services Center (CSC) to develop strategies that
fully address the available and future resource and services
support of these communities.

Developing a Living Laboratory for Examining Community
Resiliency and Recovery After Disaster
Duration: 2009 - 2011
Funding Agency: National Science Foundation (NSF)
Funding Amount: $374,036
PI: Shannon Van Zandt
CO-PI: Sam Brody, Wesley E. Highfield, Yu Xiao, Walter Peacock.
Abstract
The proposed research will build upon several existing
research initiatives along the Texas coast to provide a “living
laboratory” for examining community recovery after a disaster.
Prior to Hurricane Ike, the Texas Coastal Communities Planning
Atlas documented the physical, environmental, regulatory, and
social development patterns present along the Texas Coast (see
coastalatlas.tamug.edu). Data collection under NSF SGER #
0901605 built on this background information to provide
immediate data on impact, dislocation, and early repair and
rebuilding decisions associated with Hurricane Ike. These data
provide the baseline measures for our proposed research measure
community recovery at multiple scales over a three-year period.
Using the original sample analyzed from our quick response grant
referenced above, we will establish a series of panel studies of
households, housing units, business owners, businesses, and
business structures to track recovery trajectories and adaptive
learning. A geo-coded parcel-level dataset allows us to
aggregate units to draw conclusions at multiple scales,
including the household, neighborhood, and community.

Natural and
Human Hydrologic Interactions: Development of an Integrated
Conceptual Model and Empirical Testing in the Greater Houston
–Galveston Region.
Duration: 2009 - 2010
Funding Agency: Houston Advanced Research Center
Funding Amount: $40,000
PI: Sam Brody
CO-PI: Wesley E. Highfield
Abstract
The interactions of humans with hydrologic systems are
comprised of a constant and dynamic set of complex
relationships. In many cases these relationships are often quite
overt, including activities such as harvesting and extraction of
natural resources and damage and loss of life from
meteorological events. Other relationships are more subtle, such
as human released pollutants entering the system from non-point
sources and the introduction of invasive species. Nonetheless,
the human-natural relationships and interactions across the
hydrologic system are critical to overall environmental health,
human threats (to and from) hydrologic systems, and
social-system support. Expanding our knowledge of these
relationships is a vital first-step to better proactive planning
and management of both human and hydrologic systems. The
objectives of this proposal are twofold:
1) assemble researchers and experts to develop a broad
conceptual model of water use, water quality, and water quantity
issues in the Greater Houston-Galveston Region, and 2) begin to
empirically test specific aspects of the overall conceptual
model. The following describes the proposed study area, provides
a general approach to the collaborative development of a
conceptual model, and outlines broad ideas for empirical testing
of specific research questions identified by the conceptual
model.
