Geophysical Sciences - Dune Stabilization Project

Dune Stabilization Project
We established the Dune Stabilization Project in 1988 in conjunction with Sea Shore State Park to repair a blown out dune near the eastern boundary of the park. This effort not only provided a cheap, effective way of re-growing dunes, but also gave us an on-going, environmentally-oriented scientific study that students could engage in year after year. In addition, it helped with the added benefit of keeping trees out of area landfills. Last year, we invited several Cub Scout dens to help put the trees in.

Abstract from Virginia Journal of Science, Summer 1993, vol. 44, No.2

"The recycling of Christmas trees is becoming more widely used to assist in erosion control along the coast. From 1988 to 1993, five student groups participated in an on-going study using recycled Christmas trees to repair a dune blowout at Sea Shore State Park. Within three years, the dune was re-established. After five years, 520 cubic yards of sand has accumulated along the surveyed transect. There was negligible accumulation in the slack behind the primary dune line."

Sand accumulation three years later. We had to dig down to get to the sign
