The Use of COMSOL for Integrated Hydrological Modeling

Abstract: Hydrological processes and components are intrinsically coupled, and thus often must be modeled as an integrated system. Unfortunately, although a few modeling codes are available, integrated hydrological modeling remains a challenge. The objective of this paper is to explore the feasibility of using COMSOL Multiphysics ® for integrated hydrological modeling. In particular, using the generic boundary conditions and Richards Equation in the Earth Science Module, we set up two important boundary conditions: rainfall infiltration and seepage faces, and implement them in example simulations. Given COMSOL’s versatility and user-friendly modeling environment, COMSOL shows promise as a tool for integrated hydrological modeling
