   CUAHSI Hydrologic Information
      System (HIS) Project
• This a 2-year project to develop an RFP for the
  Center for Hydrologic Information (CHI) and
  perform preliminary research and prototyping for
  HIS
• For years 3 and onwards, all funding will be
  competitively awarded by NSF/CUAHSI
   – Center for Hydrologic Information
   – HydroInformatics Thematic Centers
• Proposal has been recommended for funding
  but is awaiting final administrative approval at

     Hydrologic Characterization
          at Observatories
• Three properties:
  – Residence time distribution within “stores”
  – Fluxes across interfaces/stores
  – Flowpaths between stores
• Conceptual model
  – Include atmosphere as part of model
  – Elaboration of stores (boxes) and structure
    must be reconciled among disciplines

          Need for spatial definition of “stores”,
              perhaps as control volumes

                            Fluxes




        Extrude watershed boundary 15 km up into atmosphere
                   and 1 km down into subsurface
      Observatory Goal: Hydrologic Fluxes

• Improve predictive understanding of fluxes of
  –   Water
  –   Sediment
  –   Nutrients
  –   [Selected Contaminants]
• Across spatial scales, including catchment outlet
• Riverine fluxes, at a minimum, but also fluxes
  across other interfaces (PI-specified)

              Need for definition of “HydroElements”,
               at any location in hydrologic system

 CUAHSI HIS… Parting Thoughts
• We want to be as open and collaborative
  as possible
• We welcome any ideas and suggestions
  you may have
• We are open to helping with additional
  proposals to other funding sources to
  leverage the CUAHSI HIS effort
