... (D₁₀–D₉₀). These results are of limited use in predicting the dewatering rate required to meet a specific standard in a full-scale geotextile tube application since, in the field, flow rate is more important than sediment piping or retention. To overcome some of the limitations...

...C. Barral; N. Touze-Foltz ABSTRACT: The objective of the paper is the presentation of a test method to quantify advective flow rates through multicomponent geosynthetic clay liners (GCLs). A procedure was developed, combining measuring devices from EN 14150 for flow rate measurement through...

...N. Touze-Foltz; M. Barroso This paper presents equations for the evaluation of advective flow rates though composite liners involving GCLs. Advective flow is due to the existence of defects in the geomembrane, and depends on the contact condition between the geomembrane and the GCL. In this paper...

...J.P. Giroud; B. Palmer; J.E. Dove There are many design situations where the rate of flow in a pipe is known and the average velocity of the liquid in the pipe must be calculated. The classical method to determine the average velocity of flow in pipes as a function of the flow rate is based...
