Investigating the Representative of Aquifer Transmissivity Determined by Passive Response Methods: A Comparison With Time‐Dependent Hydraulic Parameters Inferred From Different Stages of Pumping Tests

Water Resources Research
Aquifer pumping tests represent a standard method for estimating hydraulic characteristics, with practitioners often focusing on late period drawdown data because these are less affected by within‐ and near‐borehole effects (e.g., borehole‐storage and ...

Groundwater flow numerical model to evaluate the water mass balance and flow patterns in Groundwater Circulation Wells (GCW) with varying aquifer parameters

Acque Sotterranee, 2022
Groundwater Circulation Wells (GCW) can be an effective in-situ remediation option allowing high mass recovery of contaminants in cases where contamination hotspots are located in saturated soil having low hydraulic conductivity.

Practical Guidance for Improving Pump‐Test Based Inference of Hydraulic Parameters in Heterogeneous Unconfined Aquifers

Water Resources Research
Hydrogeological modeling relies on scale estimates for relevant hydraulic parameters. To obtain these, pump test data are typically interpreted using methods derived for idealized conditions (such as a spatially homogeneous medium).

Invariant Imbedding and the Identification of Aquifer Parameters

IFAC Proceedings Volumes, 1977
AbstractThe technique of invariant imbedding is applied to the problem of identifying the parameters in an unconfined aquifer system. This new technique is shown to be a very effective way of converting field observations based upon pumping tests into the desired aquifer parameters. The procedure is straightforward as it requires neither curve plotting

Recession flow analysis for aquifer parameter determination [PDF]

Water Resources Research, 1998
The recession flow analysis of Brutsaert and Nieber [1977] extended by Troch et al. [1993] to estimate aquifer parameters (saturated hydraulic conductivity and mean aquifer depth) is examined by means of a numerical model. It is found to be reliable for the estimation of the catchment‐scale saturated hydraulic conductivity and mean aquifer depth ...
