An analysis of groundwater flow and transport processes of arsenic in the flow domain of the Yamuna sub-basin located in West Bengal (India) is presented. The objectives of the analysis are: to conceptualize the groundwater flow domain, to determine groundwater flow paths and groundwater velocities, to study arsenic transport in the flow domain, and to study the well captures zones. The first t...

This paper presents an experimental and computational investigation of coupled consolidation and contaminant transport in compressible porous media. Numerical simulations were performed using the CST2 computational model in which a dual-Lagrangian framework is used to separately follow the motions of fluid and solid phases during consolidation. Diffusion and large strain consolidation tests wer...

A theoretical investigation of factors affecting gas phase transport of volatile organic compounds in unsaturated zone is presented. Studying annual soil temperature variation with time and depth declares that there is a considerable temperature variation in the upper few meters that may affect the overall natural mass transport of volatile organic compounds. A one-dimensional mathematical mode...

In the event of a contaminant release, atmospheric transport and dispersion (AT&D) models would be used to predict the path of the contaminant plume. If monitored contaminant concentration data are available, various assimilation techniques can be applied to incorporate the data into the transport and dispersion model, and thus, more accurately predict the plume path. We refer to this as the fo...

[1] The goal of groundwater contaminant plume interpolation is to provide an accurate representation of the spatial distribution of the plume given the data limitations associated with sparse monitoring networks with irregular geometries. Currently available methods for plume estimation cannot fully take advantage of prior knowledge of flow and transport information or the location of a contami...

The problem of groundwater contamination in an aquifer is one with many uncertainties. Properly quantifying these uncertainties is essential in order to make reliable probabilistic-based predictions and decisions regarding remediation strategies. In this work, a measure-theoretic framework is employed to quantify uncertainties in a simplified groundwater contamination transport model. Given unc...
