Drs. Witold Krajewski and Ricardo Mantilla have developed graphical user interfaces for a comprehensive model evaluation that allows for testing model performance in new regions. They have developed methodologies for rapid model implementation and parameterization, the extension of the domain of rainfall product, and techniques for data assimilation to insure high-quality food forecasts.

- 5. DIVISION VI Sec. 15. NEW SECTION. 466C.1 IOWA FLOOD CENTER 1. The state board of regents shall establish and maintain in Iowa City as a part of the state university of Iowa an Iowa Flood Center. In conducting the activities of this chapter, the center shall work cooperatively with the department of natural resources, the department of agriculture and land stewardship, the water resources coordinating council, and other state and federal agencies. 2. The Iowa flood center shall have all of the following purposes: a. To develop hydrologic models for physically based flood frequency estimation and real-time forecasting of floods, including hydraulic models of flood plain inundation mapping. b. To establish community-based programs to improve flood monitoring and prediction along Iowa's major waterways and to support ongoing flood research. c. To share resources and expertise of the Iowa flood center. d. To assist in the development of a workforce in the state, knowledgeable regarding flood research, prediction, and mitigation strategies.
