Khosrow Behbehani, dean of the UT Arlington College of Engineering, said Seo's work would have other benefits beyond flash-flood forecasting.
"Once Dr. Seo's modeling is completed, it could very easily be adapted to study the impact of development on rainfall-runoff response in an urban area. It also could examine the emergency preparedness of a city's infrastructure for water hazards," Behbehani said. "I could also see that urban areas can use this innovative system in the future to improve their water conservation programs. That's especially important in North Texas when water conservation is needed in times of drought."
The new CASA system provides very high-resolution rainfall and other data every minute compared with every five to six minutes with the existing systems. The new system focuses on a more concise area, giving forecasters detailed information to better monitor and track storms and precipitation. Because the CASA system is designed to observe the atmosphere closer to the ground, the system requires an extensive network of radars.
UT Arlington was the first institution in the North Texas region to install a CASA weather radar system. The system sits atop Carlisle Hall on the main campus. Similar systems have been installed or are scheduled to be installed at The University of North Texas in Denton and elsewhere in Fort Worth and Addison. Plans call for eight sites initially throughout North Texas.
Seo will collect real-time data from the CASA system and integrate that with information from geographic information system maps through hydrologic and hydraulic modeling.
"The strength of the CASA system is that it provides spatially detailed information at a very high temporal frequency," Seo said. "What makes this research more exciting is that this is the first system of its kind in the country because North Texas is the first metropolitan area to deploy a network of CASA radars."
