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)
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)
On-going work:Assimilation of 3-D ADCP stream data in the geodatabase
