Abstract: Automatic control of mean velocity of influent in tanks through installing properly formed weir in outlet end of tank; mathematical formula for profile of P-weir which if built into outlet end of any sedimentation tank will control outflow to produce any desired pattern of mean velocity through tank; equally applicable to tanks or channels of rectangular or trapezoidal cross section.
