BASEMENT - A freeware simulation tool for hydro- and morphodynamic modelling

The application of numerical modelling tools to river engineering problems is a well established methodology. For that purpose, the numerical software BASEMENT for simulation of hydro- and morphodynamics is developed and is available free of charge - also for commercial use. The main motivation for development of the software is to provide an powerful user-friendly tool that facilitates basic applications for practitioners as well as advanced model configuration for research. The numerical simulation software BASEMENT is developed at the Laboratory of Hydraulics, Hydrology and Glaciology (VAW) of the ETH Zürich.

The BASEMENT flyer gives a brief overview of highlighted features.  

Key features of the software

  • 1-D and 2-D hydro- and morphodynamics
  • 3-D subsurface flow
  • slope collapse
  • model coupling
  • automatic control
  • different performance concepts

The underlying one- and two-dimensional models are based on the Saint-Venant equations for hydrodynamics, the Exner-Hirano equations for bed load and an advection-diffusion approach with source terms for suspended sediment transport. Mentionable special features of the software are arbitrary combination of 1-D and 2-D model domains (model coupling), a PID controller for various monitoring values (automatic control) and use of an unstructured dual-mesh to improve topographic accuracy.
