Abstract
The paper presents two approaches used independently to estimate river discharge during an ice jam on the Yukon River near Dawson City. One method entailed the use of large-scale particle image velocimetry to obtain surface velocities, which were extrapolated and integrated to yield a discharge. Videotaping of ice-floe drift comprised the measurement method used for the large-scale particle image velocimetry. The second approach entailed numerical simulations performed with a 1-D ice-jam profile model (ICEJAM). The numerical model incorporates an "island-compensation" technique developed to take into account the difficulty of using 1-D ice-jam profile models to simulate accurately channels with two-dimensional features such as islands and bars. The two approaches yielded closely comparable estimates of river discharge.
