Abstract : This report presents a method for the use of geocomposite drainage systems as a temporary measure to improve the surficial stability of levee slopes. The mechanisms leading to sloughing failure in cohesive soils are discussed. A general overview of the use of geocomposite drainage systems in geotechnical engineering is given. Detailed design steps, ranging from estimation of required flow capacity of the drainage system to selecting the system's layout, and specifying safety factors, are described. An installation procedure and construction details are discussed. The application of geocomposite drainage systems in levees, as detailed in this report, is new; i.e., it is an extrapolation of existing practices. Therefore, it is considered a temporary measure to improve the surficial stability of levee slopes. A full-scale field test is recommended to assess the effectiveness of using geocomposite drainage systems in levees. Such an experiment will likely lead to improvements in design and construction techniques.
