Slide 1

A Synthesis of Community Data and Modeling for
Advancing River Basin Science: The Evolving
Susquehanna River Basin Experiment

Proposed Project Schedule: 12/1/06-11/30/08
PI’s: Chris Duffy, Patrick Reed, and Kevin Dressler
The Pennsylvania State University

Slide 1

Project Goal (1): Characterizing the Active Zone
 “ACTIVE ZONE” Hypothesis:
– Local watershed control volume
– 3 partitions
 1) Land surf to atm
 2) Transition zone (near surface
processes in canopy, root zone,
etc).
 3) Regolith from land surface to
subsurface boundary layer (SBL)

– SBL analogous to atm
 Effective depth (major unknown)
 Feels surface water/energy fluxes
 Operates at relevant time-scales

Slide 2

Project Goal (2): Unification of Modeling,
Digital Data, and Experimentation
 Observatory Network Design Needs:
– Must confront the tradeoffs between economic constraints,
performance objectives, and scientific knowledge gaps
– Gap analysis requires the unification of
 Multi-scale predictive modeling
 Digital data resources
 Innovative data collection strategies

 We are seeking to unify several existing efforts
– PIHM
– SRB Geodatabase
– Real-Time Hydrologic Monitoring Network (RTH_Net)

Slide 3

Major Research Components
 Penn State Integrated Hydrologic Model
– Finite volume, irregular mesh simulation
– Fully coupled process formulation
– Developed for platform independence and open source

 SRB Geodatabase
– Finalized ESRI Geodatabase for entire basin
– Soils, DEM, land cover, vegetation, etc.
– Will provide FTP access in the near term

 Real-Time Hydrologic Monitoring Network (RTH_Net)
– Exploring real-time “Active Zone” experimentation
– Developing real-time multi-state water cycle observations
