Calculation of Scour Depth at the Parks Highway Bridge on the Tanana River at Nenana, Alaska, Using One- and Two-Dimensional Hydraulic Models
This report (1) presents depths of pier scour, calculated using output from one-and two-dimensional hydraulic models, and contraction scour, calculated using output from the one-dimensional model for five discharge scenarios in the Tanana and Nenana Rivers; (2) documents construction and calibration of the hydraulic models; and (3) compares effectiveness of both types of hydraulic models in scour analyses at complex sites. Using both model types with the same geometry and flows will aid in choosing the correct approach to scour investigations at other complex sites. The study required establishing and surveying 20 cross sections on the Tanana River, developing water-surface and top-of-bank profiles, and measuring discharge and velocity at each cross section. Historical discharge data were used to calibrate and run the hydraulic models.
