项目摘要
Stretching for over 80 miles along the Illinois bank of the Mississippi River, the area of Mississippi River Floodplain known as the American Bottom is home to over 130,000 people who depend on infrastructure that controls and curtails flooding. Although the Mississippi River is the most the significant threat to floodplain communities in the American Bottom, a system of floodplain channels has triggered some of the most widespread and damaging incidents of flooding. In some cases, substantial infilling with sediment and woody material has caused these channels to literally pour into some of the most economically vulnerable communities in the US. In this EAGER proposal, the investigators will apply a new model in the practice of geomorphology, in which scientists and community members collaborate in inquiry and data collection. They will focus their initial efforts in the community of Centreville, Illinois, where the impacts of flooding have been the most damaging. They will work directly with the community to better constrain the causes and impacts of severe flooding, and to broaden their engagement with communities of the Greater St. Louis region, they are partnering with Harris-Stowe State University to offer four summer internships to rising seniors of the university. Their goal is to build meaningful and empowering undergraduate research experiences for underrepresented minorities by designing those experiences around civic engagement and environmental science.The investigators aim to demonstrate how community-centered research that is applied to managed and inhabited landscapes can, at the same time, lead to novel and impactful insights into landscape evolution. In their case, the focus is on floodplain channels of the American Bottom. Floodplain channels have been a focus of research in geomorphology for some time, but these previous efforts have largely focused on floodplain channels whose very forms are produced and controlled by lowland rivers. Floodplain channels whose forms and function are largely independent of lowland rivers, but instead are a product of upland drainages, are much less understood. The investigators will provide the first geomorphological assessment of the floodplain channels of the American Bottom, including both natural and modified reaches. By integrating field surveys, sediment coring, and numerical experiments the investigators will: 1) calculate sediment supply rates from bluff drainages into floodplain channels; 2) determine how and why sediment transport capacity varies along floodplain channels; and 3) identify flood risks associated with channel infilling for Centreville.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
密西西比河泛滥平原被称为美国底,沿着密西西比河伊利诺伊州河岸绵延80多英里,居住着超过13万人,他们依赖控制和遏制洪水的基础设施。尽管密西西比河是美国海底泛滥平原社区面临的最大威胁,但泛滥平原河道系统引发了一些最广泛、最具破坏性的洪灾事件。在某些情况下,大量的泥沙和木质材料填满了这些渠道,导致这些渠道真的涌入了美国一些经济最脆弱的社区。在这项热切的提议中,研究人员将在地貌学实践中应用一种新的模式,在这种模式下,科学家和社区成员合作进行查询和数据收集。他们将把最初的努力集中在伊利诺伊州森特维尔的社区,那里是洪水影响最严重的地方。他们将直接与社区合作,以更好地限制严重洪灾的原因和影响,并扩大他们与大圣路易斯地区社区的接触,他们将与哈里斯-斯托州立大学合作,为该大学应届毕业生提供四个暑期实习机会。他们的目标是通过围绕公民参与和环境科学设计这些体验,为未被充分代表的少数群体建立有意义和赋权的本科生研究体验。研究人员的目标是展示应用于管理和居住景观的以社区为中心的研究如何同时导致对景观演变的新颖和有影响力的见解。在他们的案例中,重点是美国海底的泛滥平原水道。滩地河道一直是地貌学研究的重点,但以往的研究主要集中在滩地河道,其形态由低地河流产生和控制。洪泛平原河道的形式和功能在很大程度上独立于低地河流,但却是高地排水的产物,人们对其了解要少得多。调查人员将首次对美国海底的泛滥平原河道进行地貌评估,包括天然河段和改良河段。通过整合实地调查、沉积物取心和数值实验,研究人员将:1)计算悬崖排水沟到泛滥平原河道的泥沙供给率;2)确定泥沙输送能力如何以及为什么沿泛滥平原河道变化;以及3)识别与Centreville河道填充相关的洪水风险。该奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
