...M.M. Khachan; S.K. Bhatia; J.L. Smith ABSTRACT: Woven geotextiles are widely used as filters in geotechnical, hydraulic, and environmental applications. Depending on the application, geotextile filters can be subjected to uni-directional, bi-directional, or cyclic-flow conditions, with cyclic flow...

... on the filtration function of geotextiles, retention and permeability criteria have been proposed. Most of the research has considered conditions that are simpler than real in situ conditions, such as cyclic flows due to the fluctuation of water table caused by sea waves, boats, or periodic drawdown of water...
