Description: Technical memorandum
General: As the use of drainage wells for relieving substratum pressures and controlling underseepage behind levees during high water is relatively new, few specific data were available for the design of various types of well screens; and as several drainage well systems are contemplated along the Mississippi River levees, the Office of the President, Mississippi River Commission, directed the U.S. Waterways Experiment Station to make a laboratory study of the discharge efficiency of various commercial brass well screens. The study was later expanded to include a field test installation of brass well screens, and to study the possible use of nonmetallic materials in the design of drainage wells. In studying the possible use of nonmetallic drainage- well several wells of this type were installed and tested in the field in conjunction with the brass well screens. Also, in order to better establish criteria for the design of all types of drainage wells, gravel filter tests and tests to determine the maximum screen sizes of a well for draining given foundation materials were performed in conjunction with the field and laboratory investigations.
