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 NSF

Hydrologic Characterizationat 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

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
