Specifying
aquifer parameters for matching and choosing the solution



Text boxes for
flow equation coefficients input. The number of boxes and their
names depend on the chosen conceptual scheme

"Isotropic
aquifer" option

Specify vertical
anisotropy (for schemes with partially penetrating well)

"Delayed
piezometer reponse included" option

Include storage
capacity and shape
factor of piezometer in
drawdown calculations (for some of the Moench’s
solutions)

"Skin"
option

Use skinfactor
for matching parameters

List

Choose
piezometer location for matching parameters

"Solver"
list box

Choose solution
for matching parameters. Occurs if the conceptual scheme can be
analyzed using several solutions

Options for data
displaying and saving


"Frequency"
frame

Specify the
precision of the graph (the number/frequency of calculation points
within the entire calculation interval) and the frequency of
calculation points saved in a file by click "Save"
button

"Draw"
frame

Options for
displaying calculation data

"Lines"
option

In the current
version of the program the displayed curve has only the
straightline view

"Redraw"
option

Switch on/off
the calculated curves updating option (when pushing
"OK"
or "Apply"
buttons)

"Save"
frame

Choose values
(either observed or/and calculated), displayed on the current plot,
for saving (when pushing "Save"
button)

"Points"
frame

Specify features
of calculation points on distancedrawdown plots

"Size"
text box

Point

"Color"
button

"Data
correction" button

Open dialog box
"Data correction"

"Numerical
inversion parameters(Moench)"
frame

Parameters for
Moench’s solutions. Applied in case of Moench’s solution
instability (see WTAQ2 and WTAQ3
program
description). The input values are saved automatically. Push
"Default"
button to return to initial values

"RERRH"
text box

Relative error
criterion for Hantush convergence (for WTAQ2 only); in the program
the parameter is used only for Moench’s solutions for linear source
in confined aquifer

"RERRNR"
text box

Relative error
for NewtonRaphson iteration and summation (WTAQ2: 1e10; WTAQ3:
1e9 to 1e10)

"RERRSUM"
text box

Relative error
for summation (WTAQ2: 1e15; WTAQ3: 1e7 to 1e8)

"XMAX"
text box

Maximum number
of terms in summation (WTAQ2: 1000 – 4000; WTAQ3: 3000)

"NS"
text box

Number of terms
used in the stehfest algorithm. this must be an even number the
value of which depends upon computer precision (8). (if the
computer holds 16 significant figures in double precision let NS =
8 to 12.).
Note: if results
are numerically unstable, as may occur if beta is very small, NS
can be reduced to 6 (or even 4). Precision will be reduced,
however, and results should be checked for accuracy

"Default"
button

Specify
parameter values for WTAQ3 program

"Recalculate"
button


Recalculate
aquifer parameters (see "Parameter calculation" dialog box
description); specify piezometer and observation well shape factors
for Moench’s solutions

"from
UCODE" button


Load parameters
from the previously solved inverse problem

"Save"
button


Save observed
and/or calculated parameter values in dat file

"Clear"
