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。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。此次洪涝灾害对城市社区环境质量的影响，特别是对土壤侵蚀和泥沙负荷的影响，是本次洪灾后亟待研究的课题。2008年6月洪水过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。由于沉积的规模和沉积物的来源尚不清楚，洪水通过城市的沉积物运输引起了强烈的科学兴趣。这种SGER必须立即启动，因为我们追踪沉积物沉积的能力将随着沉积物腐烂的示踪剂而丧失。然而，与沉积物和洪水相关的许多污染物将保留下来。该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.
