Stabilization of Sand Dunes at Vandenberg Air Force Base

A serious problem was posed by sand movement and deposition affecting the operation of coastal training facilities at Vandenberg Air Force Base. Progressive wind erosion required immediate and effective control measures. After preliminary study and experimentation with available means of erosion control, a combination of four measures was used to fulfill the assignment. These were, in chronological order of the work performed: (1) Providing a protective shale blanket in selected areas; (2) imparting cohesiveness to the unstable, noncohesive soil; (3) establishing vegetal cover; and (4) creating a foredune near the shore line as a controlled deposition zone for drifting sand. Five years of observation have proved the control measure used to be highly effective. The general applicability of the treatment to similar areas is suggested.
