Summary
Geophysical methods were used to monitor infiltration during a water release, referred to as a “pulse flow”, in the Colorado River delta in March and April 2014. The pulse flow was enabled by Minute 319 of the 1944 United States-Mexico Treaty concerning water of the Colorado River. Field work was carried out by the U.S. Geological Survey and the Centro de Investigación Científica y de Educación Superior de Ensenada as part of a binational effort to monitor the hydrologic effects of the pulse flow along the limitrophe (border) reach of the Colorado River, and into Mexico. Repeat microgravity measurements were made at 25 locations in the southern limitrophe reach to quantify aquifer storage change during the pulse flow. Electromagnetic [...]

The pulse flow was enabled by Minute 319 of the 1944 United States-Mexico Treaty concerning water of the Colorado River. Field work was carried out by the U.S. Geological Survey and the Centro de Investigación Científica y de Educación Superior de Ensenada as part of a binational effort to monitor the hydrologic effects of the pulse flow along the limitrophe (border) reach of the Colorado River, and into Mexico. Repeat microgravity measurements were made at 25 locations in the southern limitrophe reach to quantify aquifer storage change during the pulse flow. Electromagnetic induction methods were used at 12 transects in the limitrophe reach of the river along the United States (U.S.)–Mexico border, and further south into Mexico. Repeat direct-current resistivity measurements were collected at two locations to monitor groundwater elevation.
