Abstract : The report summarizes a study of inlet pressures measured in nine hydraulic models and two laboratory investigations of entrance designs for flood control outlet works. The experimental data are examined to determine the effects of upstream face geometry, guide piers, and bulkhead and gate slots. Both two-dimensional and three-dimensional flow inlets are considered and compared with free-streamline inlets. The results are presented graphically in terms of dimensionless pressure drop coefficients for use in estimating pressure conditions to be expected in design practice. Design criteria are recommended. (Author)
