This engineering manual, "Design, Construction, and Maintenance of Relief Wells: Technical Engineering and Design Guides as Adapted from the US Army Corps of Engineers, No. 3", provides guidance and information on the design, construction, and maintenance of pressure relief wells. The manual covers relief wells that are installed for the purpose of relieving subsurface hydrostatic levees, and hydraulic structures. It begins with a discussion of certain basic considerations such as foundation investigations, anisotropic conditions, and seepage analysis. Next, the manual covers the analysis of single and multiple well systems followed by the design of these wells. Successive topics discussed are the installation, inspection and maintenance, malfunctions, and rehabilitation of wells. Finally, the engineering manual provides detailed information on the mathematical analysis of underseepage and substratum pressures.
