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 年美国和墨西哥签署的《美墨水条约》的一项附加条款将允许更多地共享科罗拉多河的水。该协议要求计划于 2014 年 3 月至 2014 年 5 月发生洪水，因此需要 1.3 亿立方米的水量。水将被释放到墨西哥干涸的科罗拉多河河道中，该项目将研究新淹没的沉积物和土壤中碳和温室气体的快速流动如何影响河流的碳成分和影响。考虑到与气候变化相关的自然洪水事件的发生可能增加，这在与活跃的洪泛区隔离后的通量（陆地/海洋和陆地/大气）尤为重要。该项目将由美国学术科学家、美国地质调查局科学家和下加利福尼亚州自治大学的教师/学生合作开展。该项目将产生国际经验并为进入提供基础。变成一个该项目得到了 EAR/HS、EAR/GG、EAR/GLD、DEB/ECO 和 ISE/GVF 的支持。
