| Abstract | Recent developments in computer technology have enabled the hydrologist to carry out complex hydrologic simulations of watersheds. Parallel with the computer development has been the development of the physical and mathematical description of the various hydrologic subsystems. This study has combined the recent developments in physical hydrology to produce a physically-based digitally-simulated hydrologic model. This model uses partial differential equations solved by numerical methods to describe saturated-unsaturated groundwater flow in two dimensions and overland flow in one direction. Monte Carlo simulation was used to examine the effect that variations in the model parameters have upon the model output of surface and groundwater runoff. This simulation indicated that a large amount of error introduced into the model properties of permeability, soil moisture functional relationships and overland flow friction coefficients resulted in small errors in surface runoff, but large errors in estimates of subsurface runoff. The model was also used to provide theoretical proof of the variable source area concept which suggested that only a small portion of some watersheds contribute to storm runoff. |
