| Abstract: | Hydraulic data for shallow open-channel flow in a high-gradient flume with large bed material are reported. The bed surface consists of natural rock having particle-size range of 0.15 to 0.75 ft. Two different bed-surface configuration (roughness) were tested. The bed material was stable for all discharges. The flume wall was composed of smooth plastic and aluminum, and the test channel was 6 ft wide and 108 ft long. Longitudinal test slopes ranged from 0.008 to 0.018. Hydraulic data are reported for 103 runs with surface flows ranging from 0.7 to 32.1 cu ft/sec and for 11 runs with subsurface flows ranging from 0.1 to 0.7 cu ft/sec. Hydraulic data for all runs include water surface elevation and average bed elevation at 10 cross sections and test discharge. Detail velocity measurements at two or more cross sections are reported for selected runs. The bed-material data include shape and size properties of the rock, detailed topographic measurements of the bed surface for each of the two roughnesses that were tested, and 14 statistical parameters computed from the topographic measurements. The statistical parameters include the mean elevation of the bed, the skew of the elevations, the kurtosis of the elevations, and the standard deviation from the arithmetic mean elevation for each station.
