Abstract: The purpose of this study was to review relief well practices within the United States Army Corps of Engineers (USACE). A literature review was performed on the history and use of relief wells relief and the state of practice within the USACE. As part of this study, a survey about relief well use and maintenance practice was prepared and distributed to selected Districts containing a large number of relief wells to determine their standard operating procedures for using those wells and to learn the history of their use. Responses obtained from these Districts were tabulated and classified according to the subject categories requested. Research needs and tools were requested as part of the survey, and a large portion of the responses indicated that there is an important need for research into biofouling prevention and remediation. Finally, a laboratory experiment was performed on several commercial-off-the-shelf sensors to measure effluent flow remotely. The results of the experiment showed that remote sensing of relief well flow is viable. It was found that pore pressures could be used to measure the relief well flows over a wide range of flow rates and with an error of 10 percent or less on average. Ultrasonic sensors also performed well during testing, with an average error of 10 percent or less.
