CBET-0843110HornbuckleA 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. This SGER project is for urgent research in the aftermath of this devastating flood by investigating impact of severe flooding on environmental quality of urban communities, especially the soil erosion and sediments loading. The origin of the sediments that cover the city of Cedar Rapids in the aftermath of the June 2008 flood is the central focus of this project. The transport of sediments through the city by floodwaters is of intense scientific interest because of the magnitude of deposition and because the sources of the sediments are not clear. This SGER must be initiated immediately because our ability to track the deposition of sediments will be lost as the tracers of the sediment decay. Many of the pollutants associated with the sediments and flood waters will remain, however. This project will lead to better understanding of sediments generated by floods that impact environmental quality of flood areas.

CBET-0843110Hornbuckle 2008 年 6 月的一场洪水影响了爱荷华州东部数千人的生活。受影响最严重的是锡达拉皮兹和爱荷华大学所在地爱荷华市的社区。该 SGER 项目旨在开展这场毁灭性洪水之后的紧急研究，调查严重洪水对城市社区环境质量的影响，特别是土壤侵蚀和沉积物负荷。 2008 年 6 月洪水后覆盖锡达拉皮兹市的沉积物的来源是该项目的中心焦点。由于沉积物的规模和沉积物的来源尚不清楚，洪水通过城市输送沉积物具有强烈的科学意义。该 SGER 必须立即启动，因为随着沉积物腐烂，我们追踪沉积物沉积的能力将会丧失。然而，许多与沉积物和洪水相关的污染物仍将存在。该项目将有助于更好地了解洪水产生的沉积物对洪泛区环境质量的影响。
