Vast areas of the Mississippi River Delta are rapidly disappearing due to subsidence, dwindling sediment supply, and rising sea levels. Billions of federal dollars are currently invested in mitigation strategies to combat land loss in coastal Louisiana. These strategies include the construction of engineered diversions to direct sediment-laden flood waters to regions that have sunk beneath sea-level. In response to these urgent needs, the basic science that underpins these strategies must be advanced apace. The spring flood of 2019 lasted several months and prompted the opening of Bonnet Carre Spillway to protect New Orleans from flooding. The diverted floodwaters constructed a large deposit in the spillway. This grant supports 17 undergraduate researchers and 4 early-career investigators to collect, archive and analyze sediment data from this deposit, which serves as an analog for engineered land construction. Querying the 2019 Mississippi River flood deposits that fill Bonnet Carre Spillway will: 1) advance our understanding of the hydrodynamic controls on the sedimentary architecture of floodplain deposits, and 2) bolster models that predict the dynamics of basin filling at the outlets of sediment diversions using these hydrodynamic variables. Analyzing data from this deposit will allow the investigators to address fundamental questions in coastal restoration science. Creative scientific solutions for a diverse society require a diverse scientific workforce. The geoscience community must create accessible research opportunities that will include African American, Hispanic and Native American students, who currently comprise less than 9 percent of all students enrolled in geoscience graduate programs. This grant will improve diversity in the future geoscience workforce through targeted recruiting efforts and alliances with institutions in under-served communities. The funding facilitates an inclusive field research experience by providing financial assistance for students and opportunities to analyze collected data at home institutions amongst students’ communities. This undergraduate research framework is intended as a template for fostering diversity and inclusion in Earth science. This research will provide training for undergraduate researchers in traditional methods in sedimentology and advanced techniques in digital data collection and quantitative analysis, thereby delivering training in data-analysis to a diverse cohort of students preparing to join the STEM workforce.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.

密西西比河三角洲的广大地区由于沉降，沉积物供应减少和海平面上升而迅速消失。目前，数十亿美元的联邦资金投资于缓解策略，以打击路易斯安那州沿海地区的土地损失。这些策略包括建造工程的转移，以将充满沉积物的洪水引导到在海平面下沉没的地区。为了应对这些紧急需求，基础这些策略的基础科学必须是先进的。 2019年春季洪水持续了几个月，并促使Bonnet Carre Spillway开放，以保护新奥尔良免于洪水。转移的洪水在溢洪道上建造了一笔大矿床。该赠款支持17位本科研究人员和4名早期研究人员，以收集，存档和分析此存款中的沉积物数据，这是工程土地建设的模拟。查询填充引擎盖Carre Spillway的2019年密西西比河洪水沉积物将：1）提高我们对洪泛区沉积物沉积结构的流体动力控制的理解，以及2）增强盆地模型，这些模型预测了使用这些流体动力学变量来预测盆地填充物在销售中的动态。分析此存款的数据将使研究人员能够解决沿海恢复科学中的基本问题。潜水社会的创造性科学解决方案需要多样化的科学劳动力。地球科学社区必须创造可访问的研究机会，其中包括非裔美国人，西班牙裔和美洲原住民学生，他们目前不到所有参加地球科学研究生课程的学生中不到9％。这笔赠款将通过有针对性的招聘工作和与服务不足社区的机构的有针对性的招聘工作和联盟来改善未来地球科学劳动力的多样性。这笔资金通过为学生提供经济援助以及在学生社区中分析家庭机构收集的数据的机会来促进包容性的现场研究经验。这个本科研究框架旨在作为促进地球科学多样性和包容的模板。 This research will provide training for undergraduate researchers in traditional methods in sedimentology and advanced technologies in digital data collection and quantitative analysis, thereby Delivering training in data-analysis to a diversity cohort of students preparing to join the STEM workforce.This award reflects NSF's statutory mission and has been deemed precious of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
