REU Site: River and Coastal Restoration

这个国家科学基金会赞助的本科研究项目REU网站：河流和海岸恢复，？该项目涉及10名学生，与国家地球表面动力学中心（NCED）（www.nced.umn.edu）的科学家和工程师一起对两组关键的环境恢复问题进行为期10周的尖端研究。 学生在两个团队中的一个工作，？三角洲小队关注路易斯安那州沿海地区的问题还是土拨鼠队专注于2007年俄勒冈州土拨鼠大坝拆除的相关问题？是桑迪河。 两个团队都在明尼苏达大学的圣安东尼福尔斯实验室（SAFL）（www.safl.umn.edu）度过了6月，利用实验建模来了解他们将在该领域探索的过程。 他们还开发他们的实地研究问题，并参加科学写作，研究和伦理研讨会在六月。然后，两个小组在7月进行实地研究，一个小组在路易斯安那州沿海地区，另一个在桑迪河。 然后，两个团队返回明尼苏达大学，将他们的研究成果综合在海报和论文中。 学生们在SAFL夏季研究研讨会和校园内更大的跨学科海报会议上分享他们的海报。土拨鼠团队参加了一项正在进行的活动，记录桑迪河对2007年拆除土拨鼠大坝的地貌反应。 NCED的研究人员与州和联邦机构合作，使用高分辨率测量来编制河流如何重新分配以前被困在50英尺高的土拨鼠大坝后面的沉积物的详细记录。 这种规模的沉积物重新分布对生态栖息地有重要影响，特别是对鲑鱼物种。 该项目提供了一个真实世界的实验，对开发更有效的河流管理和恢复实践至关重要。（www.marmotdam.com）三角洲小组参与了与密西西比河三角洲海岸恢复有关的研究。 NCED？的蜡湖现场实验室提供了一个很好的机会，研究地貌和生态之间的联系，在沿海恢复的背景下。 三角洲平原的其他历史实地研究领域为学生提供了将短期项目融入地貌，地球化学和生态过程的长期视角的机会。(http地址：www.wbi.lsu.edu）

This NSF-sponsored undergraduate research program ?REU Site: River and Coastal Restoration,? involves 10 students for 10 weeks of cutting-edge research on two sets of critical environmental restoration problems with scientists and engineers of the National Center for Earth-surface Dynamics (NCED) (www.nced.umn.edu), an NSF-funded Science and Technology Center. Students work on one of two teams, ?Team Delta? focused on issues in coastal Louisiana or ?Team Marmot? focused on issues related to the 2007 removal of the Marmot dam on Oregon?s Sandy River. Both teams spend June at the St. Anthony Falls Laboratory (SAFL) (www.safl.umn.edu), at the University of Minnesota, using experimental modeling to develop an understanding of the processes they will explore in the field. They also develop their field research questions and participate in scientific writing, research, and ethics seminars in June. The teams then perform field research in July, one team in coastal Louisiana; the other on the Sandy River. Both teams then return to the University of Minnesota to synthesize their research in posters and papers. Students share their posters at the SAFL summer research symposium and at a larger, interdisciplinary poster session on campus.Team Marmot participates in an ongoing campaign to document the geomorphic response of the Sandy River to the 2007 removal of the Marmot Dam. NCED research staff, in collaboration with state and federal agencies, use high resolution measurements to compile a detailed record of how the river redistributes sediment formerly trapped behind the 50 ft tall Marmot dam. Sediment redistribution of this magnitude has important implications for ecological habitat, in this case for salmonid species in particular. This project provides a real-world experiment, critical to the development of more effective river management and restoration practices. (www.marmotdam.com)Team Delta participates in research related to coastal restoration of the Mississippi River Delta. NCED?s Wax Lake field laboratory presents an excellent opportunity to examine linkages between geomorphology and ecology in a coastal restoration context. Additional historical field research areas in the deltaic plain provide students the opportunity to integrate short term projects into a longer-term perspective of geomorphic, biogeochemical, and ecological processes.
