Analytical Method for Calculating the Flow Parameters Downstream of an Overfall Taking Into Account the Vacuum Under the Nappe

  • Published:
Power Technology and Engineering Aims and scope

An analytical hydraulic method for calculating the flow parameters downstream of an overfall taking into account the characteristic features of a falling jet is described. Design formulas are presented. The calculated results are compared with experimental data to validate the method proposed.
