Krajewski, Kruger Receive NSF Grant To Study Rainfall

University of Iowa engineers have received a $242,161, three-year grant from the National Science Foundation (NSF) to study rainfall and improve forecasts for floods, hurricanes and other weather-related phenomena.

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, and Anton Kruger, IIHR research engineer and adjunct assistant professor of electrical and computer engineering, will investigate the variability of rainfall over areas as small as one square mile and time scales of less than one hour.

The objectives of the research include improved remote sensing of rainfall leading to better control of water resource systems and more timely warnings of natural hazards such as floods, landslides and hurricanes. The field sites for the study will be located in Iowa City, northern Mississippi and Baltimore.

Krajewski says that although forecast uncertainty will always exist, if properly quantified, it may be accounted for in decision-making that affects society.

In addition to Kruger, project co-principal investigators include James A. Smith, professor, and Matthias Steiner, senior research scientist and research scholar, in Princeton University's Department of Civil and Environmental Engineering.

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 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). Kruger's expertise involves the application of information technology to the geosciences, and he is the recipient of the 2002 UI College of Engineering Research Staff Award for Excellence.
