Sediment Control and Traps
Erosion
and sediment control problems are often associated with
in stream work, road building, right-of-way construction
and slope failures. These problems can frequently be
prevented through planning and implementation of an
erosion and sediment control plan. A runoff, erosion
and sediment control plan includes the use of sediment
traps, in association with sediment control structures
to trap/retain suspended sediment on site or within
an enclosed in stream work area.
Sediment
traps are temporary or permanent sediment control structures
that reduce water velocity and allow soil particles
to settle. The remaining water is filtered through geotextile
or organic type structures, such as straw bales, before
entering a storm water system or natural watercourse.
Sediment traps are simple to construct and relatively
inexpensive; they can also be removed or vegetated to
anchor accumulated sediment. Monitoring and repairs
are important components of a sediment control plan.
Accumulated fill should be excavated and removed to
a stable location to increase the storage capacity.
These structures are often under estimated in their
sediment trapping capabilities; however, if designed,
constructed, and maintained correctly, they will contribute
significantly to the sediment control management of
a project.
