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 various flow regimes

  • 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 various flow regimes

  • Physical habitat - a surrogate for biology

  • Hydraulic Modeling Ability

    Exceeds our

    Understanding of Habitat Needs


Geomorphological research
Geomorphological Research various flow regimes

  • 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
