Eve Gruntfest is professor of geography and environmental studies at the University of Colorado, Colorado Springs. She has been working in the field of natural hazard mitigation for more than 25 years, has published widely, and is an internationally recognized expert in the specialty areas of warning system development and flash flooding. Gruntfest is coeditor of Coping with Flash Floods, which brings together papers from leading experts who participated at the 1999 NATO Advanced Studies Institute that she organized and held in Ravello, Italy. She has participated in numerous workshops sharing lessons from research on warning systems and flash flooding. Her current research project aims to change how we warn for short fuse events including flash floods and tornadoes to account for new data sources, new technologies, and new urban demographies.

Witold F. Krajewski is the Rose & Joseph Summers Professor of Water Resources Engineering at the University of Iowa. He received his Ph.D. from Warsaw University of Technology, Poland, in environmental engineering and water resources systems. He was a research hydrologist at the Office of Hydrology of the National Weather Service until 1987 when he joined the University of Iowa. His scientific interests concern multiple aspects of rainfall measuring, modeling, forecasting, and estimation using radar and satellite remote sensing. His current research focuses on modeling uncertainty of multisensor rainfall estimation at a range of temporal and spatial scales. His other work includes optimal estimation and control of water resources and environmental systems. He has published nearly 100 papers in refereed journals. He is a Fellow of the American Meteorological Society and the American Geophysical Union. He has served on numerous committees and panels of these and other professional organizations and on the editorial boards of several journals. He is a coeditor of Advances in Water Resources.
