Model Development

• Download data
• Make sure data aligns with HUCs
• Clip data to Rep Basin shapefile
• Adjust symbology as necessary
• DONE!

7
Model Development

• STATSGO refined to the project parameters

8
Utilization of Hydrologic Soil Attributes

• The model looks great but what can it be used
  for?

9
Utilization of Hydrologic Soil Attributes

• Hydrologic Soil Group

10
Utilization of Hydrologic Soil Attributes

• Available water storage at incremental depths

11
Utilization of Hydrologic Soil Attributes

• Irrigated Capability Class

12
Utilization of Hydrologic Soil Attributes

• Slope

13
Conclusion

• GIS provides nearly instantaneous data
• Association of hydrologic data with an image
• Scope of use is undefined
