Draped wiremesh and cablemesh slope protection has been utilized by states for many years to control rockfall. The initial design and specifications for these draped wiremesh slope protection systems were developed using empirical methods by WSDOT in the late 1950's for slopes that were generally less than 75 feet in height. Over the years the draped wiremesh slope protection designs have been modified by other states so that nationwide we now have a large number of variations of designs, none of which have been quantified.

Study is regionally managed. Active. The goal is to quantify and provide designs and guidance for cablemesh and wiremesh slope protection. A technical advisory committee meeting is tentatively scheduled for the late Summer 2002. (updated 2/4/01)
