Powerful validation: Instantly compare simulated streamflow with real USGS measurements at subbasins where you added gauging stations as outlets.

32D Map Information

When a 2D result map is displayed, the panel shows the current parameter name and its value for this subbasin, letting you click through subbasins to inspect specific values.

4Subbasin and HRU Info

Click Subbasin Info to see area, elevation, latitude, HRU count, and a table of every HRU with soil type, slope class, landuse code, and area percentage.

HRU composition: This reveals the internal structure driving simulation, e.g., 17.5% agricultural land on Capac soil with steep slopes, or 25.7% wetland on flat terrain.

Frequently Asked Questions

Can I edit a single subbasin?
Yes. The click panel edits at the individual subbasin or HRU level, useful for site-specific adjustments.
What do HRU codes mean?
Each HRU shows soil type (e.g., Capac), slope class (e.g., 0-0.5%), landuse code (FRSD=forest, AGRR=agriculture, WETF=wetland), and area percentage.
