Geosynthetics April/May 2021 - 33
This two-part article has presented
robust data, via two standardized test
methods, on the performance of both
SRD filtration components and " as
installed " SRD systems. These standard testing procedures are available to
assist the users of SRDs in establishing
improved construction specifications
that will guide owners and contractors to
install the correct SRD for the expected
site conditions. Yet to be invented is the
SRD that has 100% sediment retention.
Typically, when sediment retention, a.k.a.
filtration efficiency, is increased, loss
of seepage, or retention efficiency, also
increases. Both ASTM D5141 and D7351
can differentiate between SRD types used
in toe-of-slope applications. There are
''
clear performance differences, using both
methods, when evaluating filtration components and installed systems. Within
the erosion and sediment control industry, manufacturers, users and designers
must balance the known performance
characteristics when determining the
appropriate SRD to use in a specific sediment control application.
