Vertical stilling wells are economical and ideally suited to dissipate high energy flow. Model studies established general design criteria for vertical stilling wells using a standard sleeve valve. Dimensionless parameters based on design discharge Q and valve diameter D were established to aid the designer in determining optimum well size for a specific need. Over 100 tests were conducted with two laboratory models to determine stilling well geometry. A graphical method of presentation aids the designer in sizing the vertical stilling well. A design example is included.
