Designation:D735113Standard Test Method forDetermination of Sediment Retention Device Effectivenessin Sheet Flow Applications1This standard is issued under the fixed designation D7351;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method establishes the guidelines,require-ments and procedures for evaluating the ability of SedimentRetention Devices(SRDs)to retain sediment when exposed tosediment-laden water“sheet”flows.1.2 This test method is applicable to the use of an SRD as avertical permeable interceptor designed to remove suspendedsoil from overland,nonconcentrated water flow.The functionof an SRD is to trap and allow settlement of soil particles fromsediment laden water.The purpose is to reduce the transport oferoded soil from a disturbed site by water runoff.1.3 The test method presented herein is intended to indicaterepresentative performance and is not necessarily adequate forall purposes in view of the wide variety of possible sedimentsand performance objectives.1.4 The values stated in SI units are to be regarded asstandard.The inch-pound values given in parentheses areprovided for information purposes only.1.5 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026.1.5.1 The procedures used to specify how data are collected/recorded and calculated in this standard are regarded as theindustry standard.In addition,they are representative of thesignificant digits that should generally be retained.The proce-dures used do not consider material variation,purpose forobtaining the data,special purpose studies,or any consider-ation for the users objectives;and it is common practice toincrease or reduce significant digits of reported data to com-mensurate with these considerations.It is beyond the scope ofthis standard to consider significant digits used in analysismethods for engineering design.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D653 Terminology Relating to Soil,Rock,and ContainedFluidsD698 Test Methods for Laboratory Compaction Character-istics of Soil Using Standard Effort(12 400 ft-lbf/ft3(600kN-m/m3)D3740 Practice for Minimum Requirements for AgenciesEngaged in Testing and/or Inspection of Soil and Rock asUsed in Engineering Design and ConstructionD5141 Test Method for Determining Filtering Efficiency andFlow Rate of the Filtration Component of a SedimentRetention DeviceD6026 Practice for Using Significant Digits in GeotechnicalData3.Terminology3.1 For definitions of terms used in this test method,seeTerminology D653.4.Summary of Test Method4.1 Sediment-laden water is allowed to“sheet flow”up toand seep through,over,or under,or a combination thereof,aninstalled sediment retention device(SRD).At a minimum,theamount(via water and soil weight)of sediment-laden flow ismeasured both upstream and downstream of the SRD.4.2 The measurement of sediment that passes through,over,or under,or a combination thereof,the SRD compared to the1This test method is under the jurisdiction ofASTM Committee D18 on Soil andRock and is the direct responsibility of Subcommittee D18.25 on Erosion andSediment Control Technology.Current edition approved Aug.1,2013.Published August 2013.Originallyapproved in 2007.Last previous edition approved in 2007 as D7351 07.DOI:10.1520/D7351-13.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 amount in the upstream flow is used to quantify the effective-ness of the SRD in retaining sediments.3,45.Significance and Use5.1 This test method quantifies the ability of a sedimentretention device(SRD)to retain eroded sediments caused bysheet flowing water under full-scale conditions.This testmethod may also assist in identifying physical attributes ofSRDs that contribute to their erosion control performance.5.2 The effectiveness of SRDs is installation dependent.Thus,replicating field installation techniques is an importantaspect of this test method.This test method is full-scale andtherefore,appropriate as an indication of product performance,for general comparison of product capabilities,and for assess-ment of product installation techniques.NOTE1Test Method D5141 is an alternate test metho
