scientific demonstrations of tangible harm or benefit for various flow regimes
Scientific demonstrations of tangible harm or benefit for various flow regimes
  • Underlying mechanisms within components and interactions between them
  • Possible approach: Whole system experiment
    • Restoration of a highly degraded watershed
    • Scientific examination of the 5 components
    • Adaptive management
hydrologic and hydraulic research needs
Hydrologic and Hydraulic Research Needs
  • How to properly conduct multi-dimensional hydraulic modeling
    • Studies are needed that compare the results from 1-D to multiple dimension models - Does it really make a difference?
    • Is 1-D modeling reliable?
  • How to properly place/measure transects in rivers and measure/model flows, particularly in complex channels and riparian corridors
  • Develop relationships between magnitude, duration and timing of peak, low and total flows and riparian processes over a range of geographically different watersheds
hydraulic habitat
Hydraulic Habitat
  • Physical habitat - a surrogate for biology
  • Hydraulic Modeling Ability

Exceeds our

Understanding of Habitat Needs

geomorphological research
Geomorphological Research
  • How do we rehabilitate damaged watersheds?
  • What are the effects of ramping on channel geometry?
  • Methods that provide flow recommendations to protect and rehabilitate stream channels to include:
    • Intermediate and high flow recommendations
    • Flushing flow recommendations
    • Sediment and woody debris transport recommendations
    • Valley forming and maintaining recommendations
  • Relationship between channel forms and fish production
  • How to use remote sensing methods to determine channel and watershed scale flows and to monitor the effectiveness of those flows
