S&T Project 21020 Data File: Methodology to Determine the Presence of Submerged Hydraulic Jumps at Low-Head Dams

A spreadsheet tool was created to examine the hydraulic conditions downstream of a given structure over a wide range of flows. The calculations show the range over which a submerged hydraulic jump occurs and whether the surface velocity is directed upstream or downstream based on the tailwater depth at which the surface velocity “flips” direction. The calculations also show estimated surface velocities which can be compared to human swimming capability. The spreadsheet accompanies the final report for S&T Project 21020: Methodology to Determine the Presence of Submerged Hydraulic Jumps at Low-Head Dams.
