Ecological Flow Science:
Studying the relationship between flow alterations and
the ecological responses to those changes (Poff et. al. 2009)
• Flow alterations result in many complex changes
Velocity
Depth
Substrate
Nutrients
Dissolved Gases
etc…
•Biota of interest determines
Scale
River Position
Area of interest
etc…

• Nail down what “persistent habitat” means
•Ultimate goal is to extend to Trenton
• Linked 2D flow models to cover entire stretch
• Look at applying DSS approach in other systems
• Evaluate the application of hyperspectral data for bathymetry
• Include some type of ecosystem services into models
Where are we going?
