Solutions for the drawdown distribution due to the operation of well fields in coupled leaky aquifers of infinite areal extent are available. This paper is concerned with the drawdown distribution caused by the pumping of well fields in coupled leaky aquifers of finite areal extent. A transform to...
A solution for the drawdown in a large-diameter well discharging at a constant rate from a homogeneous isotropic artesian aquifer, which also takes into consideration the water derived from storage within the well, is presented. A set of type curves computed from this solution permits a determinat...
Maximum drawdown is calculated in percent, and is the most that an account has lost between all-time highs. The calculation is performed on the running account balance column. This is the Excel formula. =MIN((A1-MAX($A$1:A1))/MAX($A$1:A1),0) The rest of this post will explain ho...

The groundwater flow is Darcian toward a fully penetrating large diameter well, from which the water is withdrawn at a constant rate. For such a configuration of well and flow characteristics, the necessary continuity expressions are written for the blocks and fractures separately in addition to ...
In fact, \(\mathcal{Y}\) can be “recovered” from \(\mathscr {D}\) by the formula $$\begin{aligned} \mathcal{Y}=\left\{ Y \in \mathcal{L}^2(\Omega ) \;\big |\; \mathbb {E}[rY]\le \mathscr {D}(r)\; \text {for all}\;r \in \mathcal{L}^2(\Omega )\right...
The second integral term on the right side of the above formula (39) can be simplified to obtain expression (40): $$\psi_{wfD} (s) = \int_{0}^{{t_{BD} }} {F_{D} } (t_{aD} ,t_{BD} )e^{{ - st_{D} }} dt_{aD} + \frac{{e^{{ - st_{BD} }} }}{s}$$ ...
An analytical method for the analysis of pumping tests in fractured aquifers The formula of Cooper-Jacob has been applied to constant-rate pumping tests in fractured aquifers, by considering the fracture and matrix as two separate systems. Some time-drawdown curves which are obtained from the const...
