Introduction Mohid Land vs. Mohid Drainage Network 2D Overland flow Precipitation Variable in Time & Space 3D Porous Media 1D Drainage network Mohid Land – Integrated Model composed by a set of modules (Overland flow, Drainage Network, Atmosphere, Porous Media, etc.) Mohid Drainage Network – Standalone program which simulates in-stream processes. Data not provided simulated by the model must be supplied as boundary condition (e.g. overland flow discharge)
