Question: A model study is proposed for a barge channel (np = 0.03) that has a sedimentation problem. The channel conveys a flow rate of 10,600

A model study is proposed for a barge channel (np = 0.03) that has a sedimentation problem. The channel conveys a flow rate of 10,600 ft3/sec. The following model parameters have been established: a vertical scale ratio of 1:65 and a roughness coefficient of nm = 0.02. Determine the horizontal scale ratio, the time ratio, and the model flow. (Assume the channel has a large width-to- depth ratio, and the hydraulic radius is roughly equal to the water depth.)
