Engineers Receive $1.5 Million NSF Grant For NEXRAD Study

University of Iowa engineers have received a four-year, $1,485,481 grant from the National Science Foundation (NSF) to incorporate NEXRAD data in hydrometeorology and hydrology studies. The project may lead to better predictions of soil erosion, flooding and landslides as well as improve environmental resource management.

Project principal investigator Witold F. Krajewski, Rose & Joseph Summers Professor of Water Resources Engineering in the University of Iowa College of Engineering Department of Civil and Environmental Engineering and faculty research engineer at IIHR--Hydroscience & Engineering, will use new tools to examine rainfall data. Researchers will develop an information technology (IT) framework to analyze rainfall data from the NEXRAD radar network.

He says that the project will greatly reduce the time and effort required to locate relevant NEXRAD data and to convert it to rainfall fields that can be used to drive hydrologic models.

"NEXRAD was a multibillion-dollar investment by the nation, and we have to make sure that the use of information the system collects is maximized," Krajewski says. "As hydrologic studies often require rainfall data, NEXRAD is a great source of information. We will develop tools enabling and enhancing hydrologic and water resources research that depend on availability of rainfall data."

In addition to Krajewski, project co-principal investigators include: UI researchers Anton Kruger, Allen Bradley and Ramon Lawrence, and their colleagues at Princeton University, University Corporation for Atmospheric Research in Boulder, Colo. and the National Climatic Data Center in Asheville, N.C.

Krajewski (pronounced "cray-EFF-ski") is an internationally known researcher in the fields of remote sensing of precipitation, uncertainty assessment and hydrometeorology and a leading expert in developing algorithms for quantitative precipitation estimation using weather radar and satellite observations. Recently, he was elected a Fellow of the American Geophysical Union (AGU) and a Fellow of the American Meteorological Society (AMS) and recipient of the Outstanding Researcher Award in Water Resources from the Iowa State Water Resources Research Institute (ISWRRI).
