Abstract:

The direct computer simulation technique, discrete-element method (DEM) was applied in the development of transient, multi-dimensional mathematical models for simulating hydrologic conditions in meso-scale geophysical regions. The computational models were successfully applied to the simulations of surface-water flows in reservoirs, rivers, estuaries and coastal regions, with complex shoreline geometry and bathymetry, rainfall-runoff flows in valleys, with geometrically complex surface topography for the steep terrain, and groundwater flows through aquifer systems, with complex hydrogeologic stratigraphy.
