Uncertainty, Sensitivity And Geostatistical Studies Of Flow And Contaminant Transport In Heterogeneous Unsaturated Zone, Feng Pan

UNLV Theses, Dissertations, Professional Papers, and Capstones

The objectives of this study are: (1) to develop a methodology of estimating probability density functions (PDFs) of unsaturated hydraulic parameters when field samples are sparse, (2) to evaluate the predictive uncertainties in flow and contaminant transport due to parameter uncertainties in the layer- and local-scale heterogeneities of hydraulic parameters in unsaturated zone (UZ), (3) to investigate the contributions of the parameter uncertainties to the flow and transport uncertainties, and (4) to estimate the spatial correlation structures of hydraulic parameters by incorporating prior information and site measurements.

At layer scale, the uncertainty assessment of flow and contaminant transport in UZ …
