CRITERIA-3D is a three-dimensional agro-hydrological model for small catchments.

CRITERIA 1D is a one-dimensional agro-hydrological model. It includes soil water fluxes, crop development and crop water needs, a GIS interface (CRITERIA GEO) for geographical simulations and tools to manage crop and soil parameters. The software is written in C++ using Qt libraries, so cross-platform building is possible (Windows, Linux, MacOS)

Agrolib are a set of libraries for agrometeorological modeling and climate analysis. They include a numerical solution for three-dimensional water and heat flow in the soil, water balance, meteorological data interpolation, daily weather generator, radiation budget, snow accumulation and melt, plant development and plant water uptake.
