The SAF Stilling Basin—A Structure to Dissipate the Destructive Energy in High Velocity Flow from Spillways

This publication is a condensed report of the research that led to the development of the St. Anthony Falls (SAF) stilling basin. It is prepared especially for the use of those who have occasion to design this efficient and economical outlet structure for dissipating the destructive energy in the high-velocity flow at the exit end of chutes, dams, closed conduit spillways, and similar structures.
The experimental work begun in January 1941 was completed in December 1943. The results of the tests were first reported in a processed publication in December 1943 that was revised in May 1949 (SCS-TP-79). A detailed report on the research has been published in the Transactions of the American Society of Civil Engineers, volume 113, 1948, '^Development and Hydraulic Design, Saint Anthony Falls Stilling Basin.'' This cooperative V study in the solution of problems concerning the hydraulics of soil and water conservation structures was made by the staff of the Soil and Water Conservation Research Division, Agricultural Research
Service, U. S. Department of Agriculture, in cooperation with the Saint Anthony Falls Hydraulic Laboratory and the University of Minnesota Agricultural Experiment Station.
