Abstract
The objective of this study was to determine how the longitudinal drain system works under laboratory conditions. In this study, a bench-scale model was constructed to assess the flow patterns caused by a trench drain in a slope. The experimental variables include the trench spacing (w), seepage depth (h), and slope angle (theta). In the experimental program, four values of slope angle, three values of trench spacing and three values of seepage depth were considered. Each experiment was performed twice to ensure that the measurements are reproducible. The soil type for the experimental program was selected on the basis of hydraulic conductivity. The soil was placed in the experimental cell under dry conditions and the water was introduced at predetermined levels at the upstream end to maintain a constant head. Measurements, of seepage volume were taken along the longitudinal direction of the trench after reaching steady state seepage conditions. The piezometric pressures at selected locations in the soil slope were measured. (Abstract shortened by UMI.).
