Geomorphic response in the limitrophe region of the Colorado River to the 2014 delta pulse flow, United States and Mexico On March 23, 2014, a portion of the Colorado River bypassed Morelos Dam, the last dam on the river, and flowed into the dry river channel of the Colorado River delta. This “pulse flow” was the result of an international agreement, Minute 319, which allowed Colorado River water to be stored and released for environmental restoration. The U.S. Geological Survey participated in monitoring effects of the pulse flow, with particular emphasis on the limitrophe reach of the river, which represents the international border for 30 km between Yuma, Arizona, USA and San Luis Rio Colorado, Sonora, MX. Our...

Our ability to sustainably manage the Colorado River is clearly in doubt. The Bureau of Reclamation’s 2012 Water Supply and Demand Study demonstrated the precarious balance that currently exists between water supply and the amount consumptively used by society. A future with either declining water supplies or additional consumptive uses will undoubtedly upset this balance. This balance is threatened, because: • Climate change science predicts that watershed runoff will decline due to increased evapotranspiration from rising temperatures; and • Water users, especially in the Upper Basin, aspire to increase consumptive uses by developing new projects. This white paper describes how declining runoff and increased consumptive...

The 'Channel Width' shapefile data are measurements of the active channel width of the Green River at 1-km intervals in and near Canyonlands National Park, Utah. The active channel was defined as the area of the wetted, or inundated, channel as visible on aerial photographs plus the area of bare (free of vegetation) sand and gravel bars. The active channel for each aerial photograph series was hand digitized on a computer screen in ArcGIS version 9.2. The 'Mineral Bottom' csv data are river channel cross-sections for a 3-km study reach of the Green River upstream from Mineral Bottom, Utah. The study reach is near the mouth of Hell Roaring Canyon, 5 km upstream from the Mineral Bottom boat ramp, which is 85 km upstream...
