APEX
Agricultural Policy / Environmental eXtender (APEX) Model
The Agricultural Policy / Environmental eXtender (APEX) model is a rural region watershed model designed to determine the relationships between land use and watershed runoff dynamics. Modelled processes include rainfall-runoff dynamics, nutrient cycling, flow routing, erosion dynamics, and pesticide use.

- Model Information
- For more information about this model, go to epicapex.tamu.edu
- Spatial Resolution
- The spatial resolution is on the sub-basin to basin scale, and then further subdivided into cells. Cell size is defined by land areas with homogeneous characteristics.
- Temporal Resolution
- Time step is daily and simulation duration is on the order of years.
- Outputs
- Outputs include flow routing, nutrient cycling, erosion processes, economic assessments.
