MD Erosion and
Sediment
Control test with
100% correct
answers
woven silt film - answer used in silt fences, super
silt fences and standard inlet protections
woven monofilament - answer used in temporary
stone outlet and gabion outlet structures
Nonwoven geotextile - answer commonly used in
practices like inflow and outflow protections, at
grade, median curb inlet protections, and in all
dewatering practices
Galvanized Chain Link Fence - answer Used in
super silt fence and diversion fence
, gabion baskets - answer Used in inflow and inlet
protections, minimum 11 gauge wire, stone size
used to fill baskets 4-7"
compost - answer Decomposed organic material
that is produced when bacteria in soil break down
garbage and biodegradable trash, making organic
fertilizer
stabilized construction entrance - answer Reduces
tracking of Sediment onto roadways, provides
stable area for egress and ingress from
construction site
benching - answer Provides erosion control and
vegetative establishment for extreme changes in
grade, provides subsurface drainage where
necessary for slope stability, to be free of sediment
during construction
vegetative stabilization - answer Promotes
establishment of vegetation on exposed soil
(disturbed areas) not stabilized by other methods,
requires 95 % ground cover
