stream restoration approach
Stream Restoration Approach
  • Training and Education
  • Technical Assistance
  • Demonstration Projects
training and education
Training and Education
  • Promote Fluvial Geomorphology and Natural Channel Design Methods
  • NCTC River Science Curriculum Advisory
  • Stream Classification and Assessment Courses (Levels I, II, and III at NCTC)
  • Natural Channel Design Review Checklist
  • Stream Function Pyramid
  • Protocol Development and Training
  • Since 1994, over 1000 participants representing non-profit, local, state and federal agencies
  • Training will be used in implementation of 500 projects
  • Close to 250 miles of stream and riparian habitat restoration in 18 major river basins
types of technical assistance
Types of Technical Assistance
  • Develop Assessment and Design Tools
  • Develop Protocols
  • Conduct Watershed and Stream
  • Monitoring
  • Conduct Project Review
  • Publish Findings
demonstration projects
Demonstration Projects
  • Natural channel design methodology
  • Stream restoration
  • Fish barrier removal
stream functional pyramid
Stream Functional Pyramid
  • Hierarchical framework that categorizes stream functions
  • Each level builds on the previous level
  • Based on work Fischenich 2006
  • Functional based goals
  • Functional assessments with quantitative thresholds
  • Functional based monitoring
  • Mitigation debit and credit protocols
  • Supporting guidelines document
  • Training module
natural channel design review checklist
Natural Channel Design Review Checklist
  • Checklist of critical questions associated with NCD stream restoration projects
  • Four categories
    • Watershed assessment
    • Geomorphic assessment
    • Conceptual design
    • Final design
  • Supporting guidelines document
  • Training module
natural channel design rfp protocol
Natural Channel Design RFP Protocol
  • Checklist of critical tasks required for NCD stream restoration projects
  • Eight categories
    • SOW
    • Objectives
    • Watershed assessment
    • Geomorphic assessment
    • Alternative analysis
    • Conceptual design
    • Feasibility design
    • Final design
bank erosion rate curve
Bank Erosion Rate Curve
  • Used to estimate rate of bank erosion based on condition of bank stability
  • Provides a basis for prioritizing restoration
  • Quantifies sediment supply from bank erosion

Hydrologic Regional Curves
  • Bankfull calibration required for fluvial based assessments
  • Regional curves reduce the need for bankfull gage calibration
  • Current Curves in Maryland:
    • Piedmont, Coastal Plain, and Ridge and Valley and Allegheny Plateau Physiographic Regions
reference reach database
Reference Reach Database
  • Rosgen Stream Types C, E, and B reference stream database
  • Developed from western coastal plain streams
  • Departure from potential analysis
  • Design criteria
defining river corridors widths
Defining River Corridors Widths
  • Buffer width based on fluvial geomorphic requirements
  • Meandering streams require, at the minimum, 3.5 times the bankfull width
  • Avoid meandering floodplains
stream stability rapid assessment protocol
Stream Stability Rapid Assessment Protocol
  • Rapid stream assessment based on observation of instability indicators
  • Watershed characteristics
  • Lateral stability
  • Vertical stability
  • Stability Trend
  • Localized v.s. widespread instability
  • Potential instability cause(s)
stream feasibility assessment protocol
Stream Feasibility Assessment Protocol
  • Rapid stream assessment based on observations
  • Four evaluations
    • Existing habitat
    • Existing stream stability
    • Restoration feasibility
    • Proposed habitat
  • Quantitative score
gis stream stability prediction
GIS Stream Stability Prediction
  • GIS-based stream stability prediction model
  • GIS layers
    • Percent impervious
    • Stream slope
    • Percent forest cover
    • Forest age stand
    • Erodible soils
  • Thresholds set for coastal plain physiographic region
  • Field validated model accuracy with over 200 sites
  • Model accuracy 87 percent
stream monitoring protocol
Stream Monitoring Protocol
  • Tiered monitoring protocol
  • Tier 1 – rapid assessment based on observations of instability indicators
  • Tier 2 – monumented measurements or repair
other tools and protocols
