This seminar will cover the results of an ESTCP-funded (www.estcp.org) demonstration of the use of the high-resolution piezocone direct push sensor probe to determine direction and rate of ground water flow in three dimensions. Field hydraulic measurements can be used to determine seepage velocity distributions through interpolation methods recently incorporated into Groundwater Modeling System. Probe data comprised of soil type and co-located hydraulic information is particularly amenable to innovative data fusion based interpolations available through the modeling platform. Following chemical concentration data collection, these innovative data processing approaches allow for the determination of flux distributions at resolutions and spatial configurations never before available. Field scale data collection, interpolation, and modeling results will be presented and discussed. Final technical report for the ESTCP demonstration can be found at http://www.estcp.org/Technology/upload/ER-0421-FR.pdf.
