D. Pedretti

D. Pedretti is a researcher in the Department of Earth, Ocean and Atmospheric Sciences at the University of British Columbia, Vancouver. They specialize in hydrogeology and groundwater transport modeling, with particular expertise in anomalous solute transport in heterogeneous aquifers.

Dr. Pedretti's research focuses on the relationship between aquifer heterogeneity, statistical anisotropy, and mass-transfer parameters in radial convergent flow systems. Their work examines how directional properties of hydraulic conductivity affect the apparent capacity coefficient (β) in multirate mass-transfer models, revealing that β displays anisotropic behavior physically controlled by aquifer directional connectivity. They have developed efficient methods for estimating transport parameters from breakthrough curves and analyzing connectivity patterns in heterogeneous formations.

Analysis of their publications shows a strong emphasis on three-dimensional modeling of transport in anisotropic media, with particular attention to the effects of stratification and non-ergodic conditions on solute transport behavior. Their research bridges theoretical modeling with practical applications for groundwater contamination assessment and aquifer remediation.

• Collaborates extensively with researchers from UPC-Barcelona Tech (D. Fernàndez-Garcia, X. Sanchez-Vila)
• Works with researchers from University of Notre Dame and Colorado School of Mines

Dr. Pedretti's methodological contributions include the development of kernel density estimator approaches for capturing heavy-tailed breakthrough curves and the analysis of point-to-point connectivity in convergent flow systems. Their work provides new insights into connecting upscaled transport parameters with physical aquifer properties, which is critical for improving predictive capabilities of mass-transfer models in advection-dominated transport conditions.
