Krajewski, Kruger Receive $413,478 NSF Grant To Study Flooding

Witold F. Krajewski, professor of civil and environmental engineering in the University of Iowa College of Engineering, Rose & Joseph Summers Chair in Water Resources Engineering and faculty research engineer at IIHR--Hydroscience & Engineering, and Anton Kruger, IIHR research engineer, have received a three-year, $413,478 grant from the National Science Foundation (NSF) to test flood theory. The project, titled "Testing a Dynamical-Hortonian Scalling Theory for Flood Events on Whitewater Basin, Kansas," is a collaborative effort between Iowa researchers and their colleagues at the University of Colorado, the University of New Mexico and the U.S. Geological Survey.

The project will test a general theory on how flooding depends on spatial patterns of rainfall, topography and vegetation. The Whitewater Basin was chosen as a test bed for the project because of its special hydrologic characteristics promoting fast response to rainfall as well as availability of logistical and technical support from the Atmospheric Radiation Measurement program operated by the U.S. Department of Energy in Kansas and Oklahoma. The research will ultimately lead to improved prediction of floods for basins that lack observational infrastructure. The Iowa team, led by Krajewski and Kruger, is responsible for designing and deploying an observational network for rainfall and stream flow in the Whitewater Basin in Kansas.

In 2004, Krajewski, along with Kruger, received a $242,161, three-year NSF grant to study rainfall and improve forecasts for floods, hurricanes and other weather-related phenomena. Also, Krajewski is currently involved in developing algorithms for NEXRAD, the national network of weather radars.
