Surface Erosion on Bridge Approach using Erosion Matting
and Live Staking
Nelson, British Columbia
Kootenay Lake Forest District
To stabilize exposed side-cast material, prevent sedimentation
into the Give Out Creek domestic watershed and to prevent
surface erosion and establish vegetation.
Creek is located in the south east of British Columbia,
near the town of Nelson. A sedimentation hazard was
created within the domestic watershed of Give Out Creek
as a result of the installation of a new bridge, which
exposed soil on the downstream side of the structure.
was installed over the side-cast on the downstream side
of the bridge in the fall of 1998. The area was grass-seeded
under the coconut matting, and the matting was then
secured using live willow stakes. The site was monitored
during the summers of 1999, 2001, 2003 and 2004. The
following results were observed: stabilized side-cast
materials and good growth on the willow stakes and grasses.
