SGER: Transport of Sediments and Pollutants into the Terrestrial Regions of a Small Urban-Industrial City: The June 2008 Flood of Cedar Rapids, Iowa

2008年6月的一场洪水影响了爱荷华州东部数千人的生活。特别受到影响的是锡达拉皮兹和爱荷华州大学所在地爱荷华州的社区。该SGER项目是为了在这场毁灭性的洪水之后进行紧急研究，通过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，洪水在城市中的沉积物运输引起了强烈的科学兴趣。这个SGER必须立即启动，因为我们跟踪沉积物沉积的能力将随着沉积物示踪剂的衰减而丧失。然而，许多与沉积物和洪水沃茨有关的污染物将保留下来。这一项目将有助于更好地了解洪水产生的影响洪泛区环境质量的沉积物。

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.
