CBET - 0842682W. KrajewskiA June 2008 flood affected the lives of thousands in Eastern Iowa. Particularly affected were the communities of Cedar Rapids and Iowa City, the home of the University of Iowa. The losses at Cedar Rapids are estimated to exceed $1B; the University suffered losses of nearly $250M. This SGER award is for urgent research in the aftermath of this devastating flood by investigating hydrologic characteristics of the flood in order to improve the existing flood forecasting/warning system. A better flood warning system would give residents of endangered communities more time to prepare. The urgency of this proposed work lies in the need to quickly gain knowledge and better understanding of the principles of watershed hydrology and open channel hydraulics that should guide design of a local flood warning system. The proposed research - in the areas of the rainfall-runoff models, channel routing, and rainfall monitoring and estimation - will be conducted at the University of Iowa research institute IIHR-Hydroscience & Engineering. The ideas that the PIs will explore in this project are not ad-hoc, they are a result of their continued work on the geophysical theory of floods.

CBET-0842682W。2008年6月的一场洪水影响了爱荷华州东部数千人的生活。受影响尤其严重的是锡达拉皮兹和爱荷华市的社区，爱荷华市是爱荷华大学的所在地。锡达拉皮兹的损失估计超过10亿美元；该大学遭受了近2.5亿美元的损失。这一SGER奖是为了在这场毁灭性的洪水之后，通过调查洪水的水文特征来进行紧急研究，以改进现有的洪水预报/预警系统。更好的洪水预警系统将让濒危社区的居民有更多时间做好准备。这项拟议工作的紧迫性在于需要迅速获得知识并更好地理解流域水文学和明渠水力学的原理，这些原理应该指导当地洪水预警系统的设计。这项拟议的研究将在爱荷华大学研究机构IIHR-水科学与工程研究所进行，研究领域包括降雨径流模型、渠道布线以及降雨监测和估计。私人投资促进机构将在这个项目中探索的想法不是特别的，它们是他们在洪水地球物理理论方面持续工作的结果。
