Detection and determination of groundwater contamination plume using time-lapse electrical resistivity tomography (ERT) method
Protection of water resources from contamination and detection of the contaminants and their treatments are among the essential issues in the management of water resources. In this work, the time-lapse electrical resistivity tomography (ERT) surveys were conducted along 7 longitudinal lines in the downstream of the Latian dam in Jajrood (Iran), in order to detect the contamination resulting fro...
متن کاملGeostatistical Modeling of Electrical Resistivity Tomography for Imaging Porphyry Cu Mineralization in Takht-e-Gonbad Deposit, Iran
This work presents the application of a geostatistical-based modeling approach for building up electrical properties acquired from a geophysical electrical tomography survey deployed for the purpose of porphyry Cu exploration at the Takht-e-Gonbad deposit, in the central domain of Iran. Electrical data were inverted in 2D along several profiles across the main favorable zones of Cu-bearing mine...
متن کاملMoment inference from tomograms
[1] Time-lapse geophysical tomography can provide valuable qualitative insights into hydrologic transport phenomena associated with aquifer dynamics, tracer experiments, and engineered remediation. Increasingly, tomograms are used to infer the spatial and/or temporal moments of solute plumes; these moments provide quantitative information about transport processes (e.g., advection, dispersion, ...
متن کاملImaging hyporheic zone solute transport using electrical resistivity
Traditional characterization of hyporheic processes relies upon modelling observed in-stream and subsurface breakthrough curves to estimate hyporheic zone size and infer exchange rates. Solute data integrate upstream behaviour and lack spatial coverage, limiting our ability to accurately quantify spatially heterogeneous exchange dynamics. Here, we demonstrate the application of near-surface ele...
متن کاملبرآورد همزمان پارامترهای هیدرولیکی و انتقال املاح در خاک به روش حل معکوس در مقیاس مزرعه
Estimation of unsaturated soil hydraulic and solute transport properties by Inverse modeling has thus far been limited mostly to analyses of one-dimensional experiments in the laboratory, often assuming steady-state conditions. This is partly because of the high cost and difficulties in accurately measuring and collecting adequate field-scale data sets, and partly because of difficulties in des...
