The goal of this study has been to develop physical and digital models for research, education, and outreach. The model will be based off the US Forest Service San Dimas Experimental Watershed in the San Bernardino Mountains. Both models depict water behavior caused by precipitation through surface runoff processes. The physical model displays various watershed properties and contains different types of porous and nonporous media in order to simulate the motion of water. A flow meter has been installed to measure the surface flow rate. HEC-HMS is a hydrologic software that simulates the behavior of the physical model. The digital model provides a scaling factor for the physical model and calibrates physical model flow rates. The physical and digital model correlates to the actual watershed and demonstrate similar behaviors.
