“While we’re assessing this particular event, we’re creating a baseline for this community to build a more resilient future.”
In the aftermath of heavy flooding caused by Tropical Storm Irene, UB researchers are conducting a damage assessment that could help hard-hit communities in New York plan for future disasters.
On Sept. 10, geographers from UB’s LESAM laboratory and MCEER research center visited populated areas within the Schoharie Creek watershed west of the Catskill Mountains to photograph damage and collect corresponding GPS coordinates.
The survey covered parts of Schoharie County and Greene County, including the town of Prattsville, which was inundated by floodwaters.
The team now is combining its field site observations with hydrological data, aerial imagery and elevation data to determine the extent of the flooding and destruction.
Through data analysis and modeling, the scientists will be able to categorize the flood in the context of historical disasters. The information the researchers produce could help planners create more accurate watershed models and flood maps to better protect communities and infrastructure along Schoharie Creek from a future disaster.
“The goal of our assessment is to look back and see what happened in the past, what happened now and how we’re going to do things in the future. While we’re assessing this particular event, we’re creating a baseline for this community to build a more resilient future,” says Chris Renschler, LESAM director and MCEER investigator.
LESAM is UB’s Landscape-Based Environmental System Analysis and Modeling laboratory, and MCEER is a UB national center of excellence formerly known as the Multidisciplinary Center for Earthquake Engineering Research.
Besides Renschler, an associate professor in the Department of Geography, members of the UB reconnaissance team included LESAM postdoctoral research scientist Graham Hayes and geography students Ryan Mendieta; Alejandro Llaves, an exchange student from the International Research Training Group on Semantic Integration of Geospatial Information; and Zhihao Wang.
“We each came away with a deeper awareness of the awesome power of moving water, as well as renewed appreciation for the resiliency and kindness of people helping each other through such a tragic event,” says Hayes, commenting on the experience. “We look forward to sharing the results of our mapping efforts and analytical models with these communities.”
The visit to Prattsville was arranged by the Information Products Laboratory for Emergency Response (IPLER), a National Science Foundation Partnership for Innovation project headed by the Rochester Institute of Technology (RIT) and UB.
Renschler is a co-principal investigator of the project, whose activities include developing technologies that can provide emergency responders with real-time flood and fire maps during disasters.
The aerial imagery and elevation data the UB team is using to assess damage along Schoharie Creek was collected by IPLER collaborators from RIT and Kucera International, a private company that provides aerial mapping and geomatic services.
Tools the flight crew used to gather data included a four-camera system that combines high-resolution color with infrared imaging and a Light Detection and Ranging (LIDAR) sensor that uses laser pulses to make precision elevation measurements. These systems are the same ones the team used to gather data following the earthquake in Haiti in 2010.
Both LESAM and MCEER have been active in assessing damage and conducting research following past disasters. LESAM team members helped map damage after the 2010 Haiti quake and MCEER researchers have conducted damage assessments and related research after events including Hurricane Katrina and recent earthquakes in Haiti, Chile and New Zealand.
