ENSC 202 – 2004Phase 1 Introduction
Objectives of Phase 1
• Reference stream typing• Stream impact rating• Provisional stream geomorphic assessment
– stream condition– adjustment process– sensitivity

ENSC 202 – 2004Phase 1 Introduction
Components to Phase 1 – Step 1
• Draw the watershed boundaries
• Delineate reach breaks– Valley widths– Valley slope (contours/inch)– Geologic materials– Tributary influences (>10% watershed area)
• Name the reaches

ENSC 202 – 2004Phase 1 Introduction
Geology & Tributary criteria
• Geology: major transitions (NRCS/VTGS)
• Tributaries: above major inputs

• M#S#.# minor (<10%) tributary.reach of mainstem
• M#T#.#S#.# minor tributary.reach of a major tributaries to mainstems
