A spatially distributed hydrological model with physical bases specifically developed to facilitate the use of remote sensing and geographical information system data.

Main objectives
  • Streamflow simulation for each river reach in a basin
  • Simulation of the spatial distribution of hydrological variables (snow cover, soil moisture, etc.) on a basin
  • Computer based preparation of the data base (drainage structure and other physical characteristics) on a basin for hydrological simulations

A few applications
  • Estimation of hydrological effects resulting from changes in the physical characteristics of a basin (clear-cuts, crop change, dam,...)
  • Real time forecast of river flows using meteorological forecasts
  • Estimation of probable maximum floods from snowmelt and/or rain

Main technical characteristics
  • Most simulation algorithms based on physical processes
  • Choice of algorithms allowing a better use of all available data
  • Possible application to a large number of basins
  • Compatible with remote sensing and GIS data
  • Easy addition of new algorithms or modules
  • Simulation time steps: 1, 2, 3, 4, 6, 8, 12 or 24 hours

Distributed simulation of the following hydrological processes:
  • Meteorological data (solid and/or liquid precipitation, temperature,...)
  • Accumulation and melt of the snow cover
  • Potential evapotranspiration
  • Vertical water budget
  • Surface and sub-surface runoff
  • River routing
