MountainHydro is a software package designed to model
the summer outflow of small hilly watersheds covered with thin soils
laid on an impermeable bedrock. It is a 3D physically based distributed parameters runoff model
developed in C++ using the Microsoft Visual Studio 2005 integrated development environment.
The four modules that form the package have their own page and links to them appears up above.
- MountainWatershed : Watershed delimitation from elevation grid or from contour lines
- MountainHarvester : Canopy and soil properties from a forest ecology map
- MountainNetwork : Synthetic drainage network from elevation and soil properties
- MountainFlow : Runoff simulator
The inputs are:
- topography (raster of contour lines)
- forest ecology map (species group, stand density and height and surface deposit)
- meteorological time series (rain, air temperature, relative
humidity, wind speed and radiation)
- observed outflow for model calibration
The outputs are:
- simulated flow rate at the outlet
- Nash-Sutcliffe quality of fit coefficient
Using the meteorological times series and the forest ecology map to compute the evapotranspiration according to
Penman-Monteith equation, the model routes the net rain through the
soil matrix and the macropores. A network of surface and subsurface
channels collect the waters concentrated by the microtopography and
convey them up to the watershed outlet. |
