GeoStudio Example Verification of Sandbox Problem

This guide presents a detailed examination of the pore-water pressure distributions within a layered sandbox model, as studied by Rulon and Freeze (1985). The objective is to demonstrate the use of SEEP/W software to simulate these layered slope systems and understand the pore-water pressure distributions. The document outlines the methodology used in the laboratory experiments, including the construction of a physical model and the application of artificial rainfall to simulate real-world conditions. It describes the numerical simulation process in SEEP/W, including the selection of volumetric water content functions and hydraulic conductivity values derived from laboratory testing. The results section discusses the steady-state conditions observed in both the laboratory and SEEP/W analyses, confirming the influence of stratigraphy on seepage flow. The findings indicate that layers of less permeable material can impede seepage flow, leading to localized wet areas on the slope. The document concludes with a summary of the agreement between the numerical and physical models.
