Hydraulics of Two-Way Covered Risers

摘要

This Technical Release (TR) presents the hydraulic behavior of the covered inlet of two-way covered risers as verified by both air and water model tests at the St. Anthony Falls Hydraulic Laboratory, Minneapolis, MN. It also gives the desirable location and width of low-stage inlets as shown by model studies. Various criteria and proportions of the two-way covered riser were selected together with other pertinent hydraulic and structural standards and criteria for the Standard Covered Risers.
