Nature Gently Tests Gabion

The video below shows the first 'natural' test of the newly-completed gabion (check dam) featured in this blog, after about 1/2-inch of rain fell in Arivaca on August 15th. This runoff event was a small low velocity flash flood, so there was not much sediment buildup on the upstream side of the gabion. Inspection after the water subsided showed no erosion of sand in wash downstream of the apron.
