The main components of the confined aquifer in Tianjin are silt and silty sand. In addition,
when the recharge of a shallow confined aquifer is used in deep excavation engineering to …

Actual field pumping tests often involve variable pumping rates which cannot be handled by
the classical constant-rate or constant-head test models, and often require a convolution …

Aquifer hydraulic parameters play a critical role in investigating various groundwater
hydrology problems (eg, groundwater depletion and groundwater transport), and the Theis …

A step-drawdown test with an increasing pumping rate at each step in a fully penetrating
well is a typical procedure for estimating aquifer parameters and well losses. However …

In this study a method based on dual-well step drawdown test (ie a combination of an
aquifer and a well performance test) for the determination of hydrodynamic parameters …

Inspired by the analysis by Mishra et al.(2012) of variable pumping rate tests using
piecewise‐linear reconstructions of the pumping history, this article contains a derivation of …

Artificial recharge is an effective remediation measure for controlling groundwater level and
subsidence in many coastal cities in China. Hydraulic parameters estimated by pumping …

A new analysis technique has been proposed for interpreting transient step-drawdown test
data. The proposed method is based on taking the derivative of the drawdown with respect …

In this paper, aquifer potential in terms of sensitivity of a well in arid region is measured. Four
techniques such as Backpropagation neural network (BPNN), Radial basis function network …

This paper presents possible solutions to the problem of interactive digital globe publishing
on the Internet in connection with the recently opened Virtual Globes Museum. It describes …
