A modular modeling system for hydrodynamic and solute transport modeling
In this paper, a Modular Modeling System for simulation of flow and contaminant fate and transport in open-channel networks, called RiverNet, was introduced. The governing equations and algorithm used in this system, and the design and functionality of the software are described. By integrating flow simulation module and solute transport module into same environment and platform, it can simulate flows and contaminant fate and transport process in open-channels separately and conjunctively with user-friendly Graphic User Interface (GUI). It can solve various complex flow regimes including shock wave propagation and contaminant transport under both steady and unsteady flow regimes.
