Abstract : The control structure in the Little Sioux River in Monona County, Iowa, was designed to provide nonscouring velocities upstream in the channel and on the channel berms between the levees. The structure consists of a rectangular drop in the central channel flanked by rock sills on the berms. Tests on a 1:30-scale hydraulic model were concerned with capacity of the structure, effectiveness of the concrete drop, and adequacy of the rock protection for the sills, channel, and berms.
