HYDROTEL
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
