Groundwater constitutes a critical component in providing fresh water for various human
endeavors. Nevertheless, its susceptibility to contamination by pollutants represents a …

Skin zones with distinct hydraulic properties often form around wellbores during drilling
operations. Conventional skin-factor models, developed for low-permeability (positive) skin …

Groundwater extraction from aquifers is a common practice for human use, and variations in
groundwater levels can provide valuable information on the hydrogeological properties of …

An analytical model for describing pum** induced drawdown by constant-head test at a
partially penetrating well in a leaky confined aquifer is developed by treating the leakage of …

Aquifer pum** is a common method of meeting human water needs, but it can also disrupt
the natural flow of groundwater and cause fluctuations in groundwater levels. These …

This study proposes a new mathematical model for describing the drawdown distribution
due to a constant rate pum** (CRP) in an unconfined aquifer considering the lagging …

A Robin type boundary condition (BC), commonly adopted at stream‐aquifer interface,
excludes a term associated with streambed accounting for the effects of streambed storage …

Pum** events are often conducted in the alluvial fan due to its considerable amount of
water; If pum** events occur in the nearby vicinity of the streams, it will inevitably influence …

Oscillatory pum** tests (OPTs) provide an alternative to constant-head and constant-rate
pum** tests for determining aquifer hydraulic parameters when OPT data are analyzed …

The analytical solution model is computationally efficient and widely used to estimate aquifer
surges. Analytical solution models are computationally efficient but involving many …
