Surge studies for Portage Mountain tailrace system
Discharge of underground powerhouse at Portage Mountain rejoins Peace River through two large free-flow tunnels; surge waves in tunnels caused by changes in turbine discharge were studied by approximate manual calculations, computer analysis, and model testing; determination of initial extreme level following flow change; conditions occurring after return of surge waves reflected at tunnel exit were studied; comparison of results of three methods indicates satisfactory agreement.
