1.1 This test method is used to determine the flow rate of water and suspended solids through a geosynthetic permeable bag used to contain high water content slurry such as dredged material.
1.2 The results for the water and sediment that pass through the geotextile bag are shown as liters of water per time period, and the percent total suspended solids in milligrams per liter or parts per million.
1.3 The flow rate is the average rate of passage of a quantity of solids and water through the bag over a specific time period.
1.4 This test method requires several pieces of specified equipment such as an integrated water sampler, analytical balance, geotextile container, frame to hold the geotextile container, and clean containers to collect the decant water and a representative sample of high water content material from the proposed dredge area or slurry source.
1.5 The values stated in SI units are to be regarded as the standard. The values in parentheses are provided for information only.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
