CRITERIA3D Lab

Python version of CRITERIA-3D agro-hydrological model, it allows to configure 1D, 2D and simple 3D hydrological experiments.

• Numerical solution for three-dimensional water flow in the soil, with management of different soil horizons.
• Soil water retention curves: Campbell, modified Van Genucthen.
• Sink/source: evapotranspiration, precipitation, drip irrigation.
• Boundary conditions: surface runoff, free drainage, prescribed total potential (watertable), no flux.
• The crop coefficient varies based on monthly leaf area index (LAI).
• Other crop parameters: maximum crop coefficient (Kcmax), readily available water fraction (fRAW), shape factors of the root system.
• Input: hourly data of air temperature, precipitation, solar radiation, air humidity, wind speed, drip irrigation.
• Output (water content / water potential) at specific points in the domain.
• The software can save states and assimilate observed water potential values.

Requirements

• Cython
• VPython
• numpy
• scipy
• pandas

How to compile solverC.pyx

It requires the Cython library and a C compiler, on Windows you can use the MinGW or Visual Studio compilers.

cd src
python cythonSetup.py build_ext --inplace

If the Cython library is missing, you can run the code by setting this variable in the commonConst.py module:

CYTHON = False
