Flood Potential of Fortymile Wash and Its Principal Southwestern Tributaries, Nevada Test Site, Southern Nevada [open pdf - 3MB]
From the Abstract: "Flood hazards for a 9-mile reach of Fortymile Wash and its principal southwestern tributaries Busted Butte, Drill Hole, and Yucca Washes were evaluated to aid in determining possible sites for the storage of high-level radioactive wastes on the Nevada Test Site. [...] The study shows that Busted Butte and Drill Hole Washes (9 and 11 cross sections, respectively) would have water depths of up to at least 4 feet and mean flow velocities of up to at least 8 feet per second during a 100-year flood. A 500-year flood would exceed stream-channel capacities at several places, with depths to 10 feet and mean flow velocities to 11 feet per second. The regional maximum flood would inundate sizeable areas in central parts of the two watersheds."
