Two Engineering Professors Awarded Nearly $4 Million in Homeland Security Grants

OXFORD, Miss. – Two University of Mississippi engineering
professors have been awarded homeland security grants
totaling nearly $4 million for studies on how to predict
flood damages and improve infrastructures demolished in
natural disasters such as Hurricane Katrina.

The two awards are being administered by the U.S.
Department of Energy’s Oak Ridge National Laboratory
through the Southeast Region Research Initiative of the
U.S. Department of Homeland Security. The duration of each
award is three years.

One of the projects uses numerical computational models to
simulate the probable destruction disastrous flooding would
have on coastal cities and towns in the southeastern
region. The research focuses primarily on the environmental
impact of these simulated floods, such as water
contamination and sediment transport.

The second project involves four technical avenues to
improve the integrity of levees and floodwalls in New
Orleans and surrounding areas. The resulting proposed
better-designed structures would be more resilient in the
event of future hurricanes.

“This is yet another very strong showing by the School of
Engineering researchers,” said Kai-Fong Lee, UM engineering
dean. “With five proposals previously funded, the value and
importance of their distinguished contributions to the
national security technologies has again been recognized.”
Lee said he envisions the establishment of a Research
Center of Excellence for Homeland Security Technology on
the Ole Miss campus. “Right now it’s just a vision in our
minds, but each proposal submitted by UM researchers that
gets funded brings us one step closer to that goal,” he
said. Project titles and amounts include:

 

  • “Development of An Integrated Simulation Tool for
    Predicting Disastrous Flooding, Water Contamination,
    Sediment Transport and Their Impacts on Environment” for
    $1.8 million. Yafei Jia, associate director for basic
    research in the National Center for Computational
    Hydroscience and Engineering, is the principal
    investigator.
  • “The developed computational models will enhance regional
    resilience in the event of hazardous chemical spills
    resulting from floods caused by hurricanes and overflowing
    rivers,” Jia said. “Using numerical computational models
    and physical models we will be able to simulate these
    conditions and what is the best course of action to respond
    to them.”

    The project is to be conducted by a team of UM faculty and
    students and researchers at the University of South
    Carolina, Jia said. The computational model is to be
    developed based on the latest technologies in the areas of
    numerical analysis (the study of algorithms for problems of
    continuous mathematics), physical experiments conducted on
    site, economic systems (how business and finance relate to
    living conditions) and environmental projections (what
    ecological conditions can be anticipated in light of
    current trends), he said.

     

  • “Structural, Material, and Geotechnical Solutions to
    Levee and Floodwall Construction and Retrofitting” for $1.9
    million. Alexander H.D. Cheng, chair and professor of civil
    engineering, is the principal investigator.
  • “This project addresses the application of a number of
    creative ideas that can provide new design principles and
    retrofitting techniques to enhance the integrity and
    resiliency of levees and floodwalls in New Orleans areas,”
    Cheng said. “We propose four interrelated technical avenues
    to address the vulnerability of the hurricane protection
    system and to improve the overall integrity and endurance
    of a reconstructed system.”

    Cheng said he and three other professors – Chung Song and
    Ahmed Al-Ostaz of civil engineering, and Raju Mantena of
    mechanical engineering – a postdoctoral researcher and
    several graduate assistants will work together on the
    project. There will also be a number of subcontractors,
    including the U.S. Army Corps of Engineers Research and
    Development Center at Vicksburg.

    More than a decade ago, scientists in the NCCHE began
    developing mathematical equations for modeling the flows of
    rivers, oceans and the connections between the two, earth
    transported by rivers, changes in coastlines and shores
    created by nature, and water quality. Their software has
    been applied to assess the impacts of flooding, erosion and
    navigation maintenance during storms, hurricanes or
    typhoons. Since 2005, NCCHE has collaborated with the
    Coastal Inlets Research Program in the Coastal and
    Hydraulics Laboratory and the U.S. Army Corps of Engineers
    in the long-term research project.

    Disaster preparation has been a longtime priority for UM’s
    civil engineering faculty. Chris Mullen, associate
    professor, serves as principal investigator on the Disaster
    Resistant University, or DRU, project. Both the Federal
    Emergency Management Agency and Mississippi Emergency
    Management Agency approved the DRU plan last year. Terry
    Panhorst, assistant professor of geology, and Charles
    Swann, staff geologist at the Mississippi Mineral Resources
    Institute, are co-investigators.

    Natural hazards that threaten the university and
    surrounding area include earthquakes, floods, lightning,
    hail, severe winter weather, tornadoes, wildfires and
    windstorms.
