Presentation Transcript

  1. The Clear Creek Digital Observatory M. Muste, D. Kim, A. Kruger, D. Bennett, C. Just IIHR- Hydroscience & Engineering The University of Iowa, U.S.A.

  2. Clear Creek Digital Observatory 2004: Identification of on-campus expertise and infrastructure needed for implementation of cyberinfrastructure in water-related disciplines Assembling on-campus CI incubator: CyberEnviroNet = 25 multi-disciplinary scientists (www.iihr.uiowa.edu/cyberenvironet) Adapted from Abbott et al. (1986)

  3. Clear Creek Digital Observatory Conceptual Framework

  4. Recent Developments: Customized ArcHydro-based Data Model & database population with 3rd party available data Clear Creek Digital Observatory ArcHydro

  5. Clear Creek Digital Observatory Recent Developments:Real-time, automated data integrator for stream discharges Data source: USGS NWIS

  6. Clear Creek Digital Observatory Recent Developments:Real-time, automated data integrator for rainfall estimates & interfacing with SWAT Data source 1: NOAA Clear Creek Watershed Data source 2: Iowa Mesonet

  7. Clear Creek Digital Observatory Recent Developments:Real-time, automated data integrator for water quality Data source 2: Iowa STORET (32 stations)

  8. Clear Creek Digital Observatory On-going work (Papanicolaou, Schnoor et al.): In-situ measurements acquired with conventional and custom-built instruments • Wireless sensor network for moisture and water quality data (Nitrates) • Non-intrusive stream flow monitoring techniques (ADCP and LSPIV) • Sources of sediment & pathways (stable isotope tracers & radionucleids) • Rainfall (disdrometers, rain gages) • Bed load and suspended sediment (ISCO, sedimeters) • Permeability • Hydraulic conductivity (via in-situ instrumentation and lab-based CT) • Enrichment ratio • Phosphorus (particulate and dissolved)

  9. Clear Creek Digital Observatory On-going Work (NSF Test Bed project): Real-time, automated data integrators for in-situ measurements (moisture sensor network, water quality probes, rain gages)

  10. Clear Creek Digital Observatory On-going work: Assimilation of 3-D ADCP stream data in the geodatabase (using IIHR’s customized post-processing & uncertainty analysis software)

  11. Clear Creek Digital Observatory On-going work: Assimilation of 3-D ADCP stream data in the geodatabase

  12. Clear Creek Digital Observatory On-going work:ArcIMS: extraction of geospatial and attribute information from the geodatabase & interfacing data with users via the internet
