1. Stream Geomorphic Protocols Introduction Vermont Stream Geomorphic Assessment Protocols Extracted from Vermont ANR Stream Geomorphic Assessment Protocols Handbook - Introduction

2. Stream Geomorphic Protocols Introduction geo-morphic = land-shape “Fluvial geomorphic science explains the physical river processes and forms that occur in different landforms and geologic and climatic settings.” Rivers are dynamic but predictable Disturbance by people affects natural physical processes Changes in channel form (or type) are at least partially reversible (management and restoration are is possible) Channel form (or type) influence erosion and flood hazard risk levels and aquatic habitat quantity and quality.

3. Stream Geomorphic Protocols Introduction What is the VT/SGA supposed to do? create a data collection protocol that is scientifically sound, reproducible, and comparable create a database system for users inside and outside the Agency of Natural Resources. create a robust method to support conflict resolution and promote sound land use practices and planning at the watershed scale. create a river assessment methodology, understandable to lay people, that informs rather just advises

5. Stream Geomorphic Protocols Introduction Physical Processes & Interactions in Rivers

6. Stream Geomorphic Protocols Introduction Consequences of Land/River Management

7. Stream Geomorphic Protocols Introduction Stream Geomorphic Condition as an Assessment Tool In Regime – a stream reach in reference & good condition that: –Is in expected dynamic equilibrium –Provides sustainable, high quality aquatic and riparian habitat In Adjustment – a stream reach in fair condition that: –Has change or is changing outside expected range –Has somewhat degraded aquatic and riparian habitat Active Adjustment and Stream Type Departure – a stream reach in poor condition that: –Has strong departures from the expected range, perhaps a new type –Has clearly degraded habitat, frequently disturbed

8. Stream Geomorphic Protocols Introduction Phases of the SGA Phase 1 – desk top data gathering Phase 2 – field data gathering Phase 3 – field engineering survey

9. Stream Geomorphic Protocols Introduction Data Management and Quality Assurance Take time to learn the protocols Regularly review your data; double check each other Manage your data systematically
