GE 4001 - Evolution
of Flood Control Engineering
Dry ephemeral channel in the central Mojave Desert, near Rock Springs in the Mid Hillsarea.
This view is looking upstream at the rock-alluvium transition, as it appears duringmost of the year.
Note the child running for scale.
The same channel near Rock Springs during a flash flood event on June 16, 1969.
During high flows the channel bed is scoured significantly, such that 10-feet high
standing waves are developed. Note the extreme turbidity of the runoff, which
decreases the effective weight of the suspended bedload as much as 90%.
