    New Guide for Determining the Effective Flow Rate per Unit Width and Effective Hydraulic Transmissivity of Multi-Linear Drainage Geocomposites.

    (What is a Work Item?)

    Developed by Subcommittee: D35.03 | Committee D35 | Contact Staff Manager


    1. Scope

    1.1 This guide describes the procedure for determining the effective flow rate and effective hydraulic transmissivity of a multi-linear drainage geocomposites under varying normal compressive stresses and a constant head, assuming the infinite-flow width concept is applicable. 1.2 The infinite-flow width concept identifies a width that is appropriately large to consider the individual, localized contribution of the single drainage conduit not significant to the entire scale of the project. This infinite-flow width concept likely varies from project to project and must be reviewed for validity by the project design engineer before use.
