1
Assess Riparian Condition Through Spectrometric Imaging Of Riparian Vegetation Project ID: 25011 Presented by Brian Kasper Water Quality Analyst/Modeler
2
Project Goal: Digitally map and describe riparian vegetation in Columbia Plateau Province subbasins within Oregon.
3
Proposal Area: ~24,700 miles of streams Red = 3,381 miles on 1998 303(d) List
4
Why? Oregon must develop Total Maximum Daily Loads (TMDLs) for all 303(d) listed water bodies. TMDLs require pollution source assessments and computer modeling. Water quality (i.e., temperature) depends upon riparian vegetation conditions.
5
Color Aerial Analysis: Veg Map Elements: 1) Species 2) Height 3) Canopy Density Scale = 1:5000 Buffer = 300 feet
6
Product: Current Condition Vegetation Chart
7
Product: Shade Assessment 0-20% 20-40% 40-60% 60-80% 80-100%
8
Product: Shade Assessment
9
Example Application: Modeling Temperature
10
Beneficial Uses: TMDL development & implementation is aimed at Salmonid preservation. Effectiveness of current riparian conditions on water quality may be assessed. Watershed enhancement projects can be prioritized based upon the riparian assessment.
11
Cost Analysis: Vegetation Mapping (includes materials, data preparation, digitizing, ground truthing, GIS sampling) $100 per stream mile $175,000 - FY2002 $100,000 - FY2003 $85,000 - FY2004
