SUTRA
Saturated-Unsaturated TRAnsport
Saturated-Unsaturated TRAnsport (SUTRA) is a groundwater model that captures saturated and unsaturated flow dynamics in the subsurface. It also simulates pollutant transport and sorption processes for contaminants.

- Spatial Resolution
- Spatial resolution and mesh sizes and shapes are variable. Spatial scale is user defined.
- Temporal Resolution
- Temporal resolution is variable and set based on the time steps over which input parameters vary. Smaller time steps are correlated with increased accuracy of model results.
- Outputs
- Outputs specifics include water quality characteristics.
