  1. Rapid Stream Assessment Model John Hawkins & Chris Park Rogue River – Siskiyou NF

  2. Agenda • Short Presentation • Demo Running Model • Demo ArcMap Outputs • What next

  3. Introduction • Developed under Inter-Agency Agreement • USFS • Oregon DEQ • BLM • Used to Automate Water Quality Restoration Plans (WQRP)

  4. Overview • AML program - ArcMap maps - msAccess • History: • Based On Shadow 1980’s -1993 • Lotus123 Spreadsheet Predicted temperature increases from management activity • Area is limited by the extent of the vegetation coverage

  5. 5 Input Covers • Integrated Vegetation Mapping Project (IVMP) • Vegetation Crown Closure (VEG) • Vegetation Size (QMD) • Watershed • Land Use Allocations • Digital Elevation Model 10 meter (DEM)

  6. 0 57 10 5 effective shade buffer Shadow Regression • = -23.1 - (.1327 * (ln(tree_avg) * ln(stm_width))) + (10.37 * pow(stm_width, -.1559)) + (11.38 * pow(tree_avg, .1116)) - (.5434 * cos(stm_orent.rads)) + (.2487 * slope_avg) + (.4204 * (cos(stm_orent.rads) * ln(stm_width))) • 5 Inputs Needed for Shadow • Tree Height • Stream Width • Stream Orientation • Side Slope • Canopy Closure

  7. Stream Width Stream Width (feet) = 12.19*Area^^.39

  8. 1 1 1 2 1 1 2 3 4 “Cross Sections” Determined Input to Shadow Regression • Find Areas that provide Shade to Stream • Give Unique Values to the Stream network • Use Euclidean and Zonal distance Functions

  9. Existing vs. Potential Shade • This allows you to start playing what if games with thinning and planting. • Identifies what areas may respond to management. • Based on simple ArcMap queries • Grow trees in Active Management Areas • Height to Site Potential Tree • Crown closure to 60%

  10. Demo • Starting • Menus • ArcMap • Reports

  11. Products • 3 Predefined ArcMaps • 20 Layer files • Numerous Covers and grids • 1 msAccess Database

  12. Limitations - Considerations • IVMP is intended for use at larger scope. It is suitable at the 5th field watershed and above. • Stream Network is defined by the DEM’s

  13. What’s Next • Move away from AML’s and into Geoprocessing and Visual Basic • Move data into a geodatabase • Move program to Ctrix

  14. Where to Get More Information • The program is located on the FTP site. • ftp://ftp2.fs.fed.us/incoming/r6/sis/jhawkins/StreamAssessment/ • includes documentation and install instructions. • jhawkins@fs.fed.us
