Abstract

To investigate the influence of pool elongation on turbulence production and energy slope, a flume experiment was conducted with a pool geometry that was loosely based on a 0.10 scale model of a forced pool from North Saint Vrain Creek, Colorado. Based on the overall flow pattern, the strongest turbulence occurs in the center of the pool along the shear zone between the jet and recirculating eddy. The lateral location of this shear zone is sensitive to changes in pool length. The results indicate some form of hydraulic optimization is possible with pools adjusting their length to adjust the location and strength of turbulent intensities in the center of pools, and lower their rate of energy dissipation
