Groundwater assessment and modeling

Assessment of parametric uncertainty for groundwater reactive transport modeling

The validity of using Gaussian assumptions for model residuals in uncertainty quantification of a groundwater reactive transport model was evaluated in this study. Least squares regression methods explicitly assume Gaussian residuals, and the assumption leads to Gaussian likelihood functions, model parameters, and model predictions. While the Bayesian methods do not explicitly require the Gauss...

Residential History and Groundwater Modeling

Transient groundwater modeling using spreadsheets

This study proposes a transient groundwater modeling using spreadsheet simulation (TGMSS) model for solving groundwater problems. TGMSS may be considered as a practical method and introduction to groundwater modeling that uses spreadsheets instead of conventional groundwater model codes. Irregular aquifer geometry, variable boundary conditions and sinks and/or source values, heterogeneous aquif...

Entropy Theory for Groundwater Modeling

Abstract For over two decades entropy theory has been applied to groundwater modeling with particular regard to (1) groundwater head, (2) parameter estimation, and (3) contaminant transport. Entropy theory is formulated in two domains: real domain and frequency domain. In the real domain, the theory comprises (a) Shannon entropy or another form, (2) principle of maximum entropy, (3) relative en...

Assessment of Groundwater Pollution Risk

Q.5-How do I assess the risk of groundwater quality problems arising from pollution of urban aquifers? Written specifically for this Web-site by Brian Morris and Stephen Foster, drawing extensively from Foster and Hirata 1988, Morris and Foster 2000 (see references) and unpublished material.
