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.

1944年美国与墨西哥之间的美国 - 墨西哥水条约的补充将使科罗拉多河的水共享更多。该协议要求举行洪水事件，计划于2014年3月至2014年5月，其中1.3亿平方米的水将被释放到墨西哥干旱的科罗拉多河河道。该项目将研究新近洪水的沉积物和土壤中碳和温室气体的快速动员，影响河碳成分和通量（陆地/海洋和土地/陆地/大气），之后是在活跃的洪泛区隔离之后。鉴于与气候变化相关的自然洪水事件的发生可能增加，这尤其重要。就理解这种生态系统恢复工作的意外后果而言，这也是一项重要的研究。该项目将作为美国学术科学家，USGS科学家和教职员工/学生的学生之间的协调合作进行。该项目将产生国际经验，并为进入显着范围的碳循环问题提供基础。该项目由EAR/HS，EAR/GG，EAR/GLD，DEB/ECO和ISE/GVF支持。
