| Sammanfattning≠ | MODFLOW is the U.S. Geological Survey's open-source, modular finite-difference model for simulating three-dimensional groundwater flow through porous media. First released in 1984 and continuously updated — most recently as MODFLOW-6 — it is the global standard for quantitative hydrogeological analysis, widely used in civil engineering, environmental consulting, water-resource management, and groundwater contamination studies. | The Bishop and Janbu methods are limit equilibrium approaches for analyzing slope stability, computing the factor of safety against shear failure along a potential slip surface. Developed by Bishop (1955) and Janbu (1954), these methods remain the most widely used tools in geotechnical engineering for evaluating cut slopes, embankments, and natural hillsides. | Soil-structure interaction (SSI) analysis accounts for the dynamic coupling between a structure and its supporting foundation soil, recognizing that the soil is not infinitely rigid. Formalized by Veletsos in 1974, this approach reveals how foundation compliance, radiation damping, and kinematic effects modify the structure's seismic response compared to fixed-base assumptions. |
