CUAHSI Hydrologic Information System (HIS) Project

• CUAHSI Standing Committee on HIS functioned from
  Fall 2001 to Fall 2003 and guided the proposal
  development
• NSF Project was awarded on April 1, 2004
• This a 2-year project to define the requirements
  for a Center for Hydrologic Information (CHI) and
  to develop a prototype HIS
• Plan for years 3 and onwards is that NSF will
  hold competitions for
• Center for Hydrologic Information
• HydroInformatics Thematic Centers

Environmental Cyberinfrastructure

• Part of NSF Cyberinfrastructure program
• Special emphasis on environmental sciences
  fostered by Margaret Leinen (Asst Dir for
  GeoSciences)
• CUAHSI Hydrologic Information Systems is one of
  several pilot projects

HIS Data Organization
Hydrologic Fluxes and Flows
Digital Watershed(Atmospheric, surface and
subsurface water)
Hydrologic Digital Library Digital files of
hydrologic information in any form (ADOs),
indexed by a metadata catalog (.MIF)
Arbitrary Digital Object (ADO)

Sensor Network Interfaces to Digital Library
Example is for wireless network in Santa
Margarita watershed, San Diego

Hydrologic Data Model
Hydrologic Fluxes and Flows
Digital Watershed(Atmospheric, surface and
subsurface water)
We need to represent the physical environment
and water flowing through it

Digital WatershedAn implementation of the
CUAHSI Hydrologic Data Model for a particular
region
Created first for the Neuse basin

Unidata Atmospheric Science
Precipitable water in the atmosphere
Cross-section of relative humidity
Wind vectors and wind speed (shading)
Images created using Unidatas Integrated Data
Viewer (IDV)
Unidata delivers real-time weather data
including Nexrad to more than 100 universities

Create a 3 dimensional representation
Geovolume
Each cell in the 2D representation is transformed
into a 3D object
Geovolume with model cells

What is a Modelshed?

• A volumetric spatial model registered in three
  dimensions by a GIS, with which time-varying
  data, model fluxes, spatial relationships and
  descriptive metadata are associated

HIS Info for HO Proposals
Now
Interact with HO Proposers to clarify data
requirements
Draft HIS White Paper Review by HIS Users
Committee Revision
HO announcment is made by NSF HIS White Paper
published by CUAHSI
HO Proposals are submitted
HIS White Paper will define what centralized
services the HOs should expect to be provided to
them

EducationGIS for Water Resources

• Graduate course taught jointly between Univ. of
  Texas and Utah State Univ.
• All lectures in video streaming format and
  supporting class materials are archived and
  available free of charge on internet
• Class starts this Thursday
• Grad hydrology class taught similarly next Spring
• An Arc Hydro book available here for each HO team

26
Conclusions

• A good start has been made with HIS
• Digital Hydrologic Library and Digital Watershed
  ideas are reasonably well formulated
• Work on mass balances, fluxes and flows is
  developing
• We want to support you in making your HO
  proposals to the extent we can
