DataEnterGrid
is a grid to enter data in pairs such as time and depth or time
and drawdown.
You can save the data in Wellpro's native format or save the data in CSV format for use in a spread sheet.

Pumping test Drawdown
This program uses Cooper Jacob to compute transmissivity and Storage coefficient
under nonequilibrium conditions for a confined aquifer.
Example output
Correlation coefficient= 0.99946
Transmissivity Metres^2/day = 1178
Storage coefficient  = 0.00016532   Pumping rate =   2500  Metres^3/day
Distance to observation point  =   60    Metres To =  0.32396  minutes
Time Minutes          Drawdown Metres

Below is an display of the data where time is LOG drawdown is Linear. You may also choose LOG drawdown time Linear, both LOG or both
Linear.     Or switch sense (reverse) axis.     Change background color and more!
Pumping test Drawdown(UC)
This program uses Cooper Jacob to compute transmissivity and Storage coefficient (specific yield)
under nonequilibrium conditions for a unconfined aquifer
Pumping test steady state
This program uses the equilibrium or Thiem equation to determine the
the Transmissivity of an confined aquifer.
Pumping test steady state(UC)-This program uses the equilibrium or Thiem equation to determine the the Transmissivity of an unconfined aquifer.
Slug
There are two slug test programs. The Horslev program which uses the method of the same name and the Bower,Rice program
Distance-Drawdown
The program uses a pumping well that has been pumping at a constant rate for a period of time and the drawdowns in a series of wells or bore holes some distance away to determine
transmissivity and storativity.
Find Distance-Drawdown(Theis)
This program uses the Theis equation to find the drawdown with distance from a pumping
well when pump rate, transmissivity, storage coefficient and pumping time in days are known
Recovery
This program evaluates the data from a well recovery test to determine transmissivity
Recovery2
also calculates a value for the storage coefficient using the recovery of an observation well plus transmissivity.
Distance to boundary
Distance to boundary2
Distance to boundary or Distance to boundary2 "in case of faulting".    The inputs are "To" given in the results from a pumping test.    "Ti" or the time where the break in slope occurs.
   In this example after clicking on the box labeled "Show drawdown values" the graph shows the break at a drawdown of 0.72 .   
Find the corresponding time in the list below 24 minutes.   This is Ti.  
The programs then calculates the distance to a pinchout or fault from the pumping well.
(Right click on chart then click on x axis log for lin. depth vs log time display)
Graph
This program lets you graph data either manually input or from a file
Falling tube
The falling tube method is a simple inexpensive and effective way of measuring
saturated hydraulic conductivity(ksat) of soils in the field.
Salt
Program fresh salt finds depth to fresh water salt water interface
Salt upconing finds the height of unconing of salt by a pumping well.
Critical upconing finds the
maximum pumping rate to prevent well contamination by saltwater
Radius of influence
The radius of influence is the distance from a pumping well where the drawdown is zero for a given pumping time.
Distance to drawdown of
This programs determines the distance to a drawdown of a certain value by a well that
has been pumping at a constant rate for a period of time when the transmissivity and
storativity is know.
Theis
This method determines transmissivity and storativity by curve matching a Theis type cure to the data derived
from pumping one well at a constant rate and measuring the drawdown over time in an observation well some distance away.
Q-Drawdown
Q-Drawdown gives the relationship between pumping rate and drawdown at a given distance over a fixed time.
Capture zone
The equation that defines the extent of the capture zone of a pumping well under steady-state conditions is given by:
x = -y/tan(2PiTiy/Q)
Where ;
x = the distance from the pumping well alone the flow axis
T = transmissivity (k *b) where k is the hydraulic conductivity and b is the aquifer thickness
i = is the hydraulic gradient without pumping
y = maximum width of the capture zone divided by two.
The distance from the pumping well to the stagnation point or end of the capture zone downstream is given by
