Standard Test Method for Determination of Temporary Ditch Check Performance in Protecting Earthen Channels from Stormwater-Induced Erosion
|Publication Date:||15 May 2006|
|ICS Code (Construction of waterways, ports and dykes):||93.140|
This test method covers the guidelines, requirements, and procedures for evaluating the ability of temporary ditch checks to protect earthen channels from stormwater-induced erosion. Critical elements of this protection are the ability of the temporary ditch check to:
Slow and/or pond runoff to encourage sedimentation, thereby reducing soil particle transport downstream;
Trap soil particles up stream of structure; and
Decrease soil erosion.
This test method utilizes full-scale testing procedures, rather than reduced-scale (bench-scale) simulation, and is patterned after conditions typically found on construction sites at the conclusion of earthwork operations, but prior to the start of revegetation work. Therefore this test method considers only unvegetated conditions.
This test method provides a comparative evaluation of a temporary ditch check to baseline bare soil conditions under controlled and documented conditions.
