The primary purpose of this study is to evaluate the validity of this bi-level theory with a viscous-flow analog. Viscous-flow analogs have been used by many investigators in the past to evaluate analytical solution to drainage problems (Bear, 1972). The objectives of this study are: 1. Design and construct a viscous-flow analog for laboratory and classroom use, 2. Test the reliability of existing bi-level drainage theory with the analog, and 3. Provide design data for use in the solution of bi-level drainage problems. The bi-level drainage theory will be graphically presented for design purposes provided the theory is shown to be reliable. If it is determined that the theory fails to predict the analog data, then the analog data will be presented in a graphical form for use in design.
