CRITERIA3D
Overview
CRITERIA‑3D is a three-dimensional hydrological model designed for small catchments.
It includes a numerical solution for three-dimensional water and heat flow in the soil, coupled surface and subsurface flow, meteorological data interpolation, radiation budget, crop development and crop water uptake, slope stability analysis.
It needs hourly meteo data as input (air temperature, precipitation, solar irradiance, air relative humidity, wind speed).
See last release to download precompiled binaries.
Key Features
- 3D water flow simulation in both surface and subsurface layers.
- radiation budget
- canopy development and water uptake
- snow accumulation and melt model
- slope stability analysis
- hourly meteorological data interpolation
Applications
CRITERIA‑3D can be used by:
- Hydrologists and environmental engineers for catchment water balance studies.
- Researchers analyzing surface-subsurface interactions and hydrological processes.
- Civil planners for land management and flood risk assessment.

CRITERIA is operational at Arpae Emilia-Romagna. It has been used in several international projects (Vintage, Highlander, Arcadia) and it is reported in the International Soil Modeling Consortium.
Step-by-Step Compilation Guide
1️⃣ Install required software
Make sure you have:
- Qt 5.x or later
- QtCharts module (install with Qt)
- Qt5 Compatibility module (Only for Qt 6.x)
Also, install Qt Creator (the IDE for building Qt projects).
2️⃣ Build projects in Qt Creator
Open and build the MapGraphics (GUI) project:
\MapGraphics\MapGraphics.pro
Go to Build → Build Project
Open and build the main project:
\bin\Makeall_CRITERIA3D\Makeall_CRITERIA3D.pro
Build it the same way
⚠️ Important Tips
- Always build MapGraphics.pro first, then the main project.
- For both projects, go to Projects → Build Settings in Qt Creator and uncheck “Shadow build”. This prevents common compilation errors.
3️⃣ Run CRITERIA-3D
After successful compilation:
Locate the executable in the build folder
Run it directly from Qt Creator or your system file explorer.
soilFluxes3D library
agrolib/soilFluxed3D is a numerical solution of flow equations of water and heat in the soil, in a three-dimensional domain.
Surface water flow is described by the two-dimensional parabolic approximation of the St. Venant equation, using Manning’s equation of motion. Subsurface water flow is described by the three-dimensional Richards’ equation for the unsaturated zone and by three-dimensional Darcy’s law for the saturated zone, using an integrated finite difference formulation. The available boundary conditions are surface runoff, culvert runoff, free drainage (lateral or deep) and prescribed total potential.
Water fluxes equations may be coupled with the heat flux equations, which include diffusive, latent and advective terms. Atmospheric data (net irradiance, air temperature and relative humidity, wind speed) could be used as top boundary conditions.
