Abstract:

Navigation in island reaches causes return velocity in the main channel as well as water movement behind the island in the side channel. The magnitude of the velocity was shown to depend on the length of the island. For the cross section and two configuration used herein, islands less than 300 ft in length can be ignored and the entire cross section used to compute return velocity. For island lengths greater than 2,100 ft, the cross section between the island and the far bank can be used to compute return velocity in the main channel. Data are presented to determine return velocity in the main channel and side channel velocity for island lengths between 300 and 2,100 ft.... Navigation, Return velocity, Velocity
