Collaborative Research: Flooding the Colorado River Delta: Impacts of Flow Restoration on River-Carbon Composition and Fluxes

美国和墨西哥1944年签署的《美墨水资源条约》将允许更多地分享科罗拉多河的水资源。这项协议要求在2014年3月至2014年5月期间举行洪灾活动，届时将有1.3亿立方米的水被释放到墨西哥干燥的科罗拉多河河道中。该项目将研究在与活跃的泛滥平原隔离后，新淹没的沉积物和土壤中的碳和温室气体的快速动员如何影响河流的碳组成和通量(陆地/海洋和陆地/大气)。鉴于与气候变化有关的自然洪灾事件可能增加，这一点尤为重要。就理解这种生态系统恢复努力的意外后果而言，这也是一项重要的研究。该项目将作为美国学术科学家、美国地质调查局科学家和下加利福尼亚大学的教职员工/学生之间的合作项目。该项目将产生国际经验，并为进入一个大范围的碳循环问题奠定基础。该项目得到了EAR/HS、EAR/GG、EAR/GLD、DEB/ECO和ISE/GVF的支持。

An addition to the 1944 U.S.-Mexico Water Treaty between the United States and Mexico will allow for greater sharing of water from the Colorado River. This agreement calls for a flooding event, planned for from March 2014 to May 2014, whereby 130 million m3 of water will be released into the dry Colorado River channel in Mexico. The project will examine how rapid mobilization of carbon and greenhouse gasses in newly flooded sediments and soils, affect river-carbon composition and fluxes (land/ocean and land/atmosphere), after being isolated from an active floodplain. This is particularly important in light of possible increases in the occurrence of natural flooding events associated with climate change. It is also an important study in terms of understanding the unintended consequences of such ecosystem restoration efforts. The project is to be conducted as a cooperative venture between US academic scientists, USGS scientists and faculty/students from the Universidad Autónoma de Baja California. The project will generate international experience and provide a basis for entry into a carbon cycle problem of significant scope. This project is supported by EAR/HS, EAR/GG, EAR/GLD, DEB/ECO and ISE/GVF.
