Abstract : Tests were conducted on a 1:12-scale model of a rectangular drop structure designed to stabilize channel beds and minimize bank erosion in the Gering Valley drainage system. The majority of the tests were conducted on a 33-ft-wide structure with a drop height of 5 ft. Discharges up to a maximum of 6000 cfs were observed. Verification of generalized data was accomplished by tests on a structure with a 10-ft drop height. Of primary concern were development of the optimum dimensions for the various elements of the structure and determination of riprap requirements in the vicinity of the structure. (Author)
