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

Statistics
Created first for the Neuse basin and then for each of the following CUAHSI Observatory Planning basins
Digital Watershed:An implementation of the CUAHSI Hydrologic Information Data Model for a particular region
Data from the Center for the Analysis & Prediction of River Basin Environmental System @ Duke University

Neuse River Basin Data Themes
STATSGO - General soil survey data
Land Use / Land Cover Data
Dams
Stream flow gages
Watersheds
Digital Elevation Model
plus lots of time series of water resources monitoring data…..
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
3D Control Volume of Neuse Basin
Fluxes
Extrude watershed boundary 15 km up into atmosphereand 1 km down into subsurface
