Pumping from two aquifers

 

"Pumping from two aquifers" dialog box.

 

Explanatory table

"Q, m^3/day" text box

Constant pumping rate of a well (screen in bottom aquifer)

"Q2, m^3/day" text box

Constant pumping rate of a well (screen in the upper aquifer)

"t, day" text box

Time for which drawdown is calculated

"s, m" text box

This field shows calculated drawdown in bottom aquifer. Entering a value in this field re-calculates the pumping rate

"T2, m^2/day" text box

Transmissivity of the upper aquifer

"a2, m^2/day" text box

Hydraulic diffusivity of the upper aquifer

"s2, m" text box

This field shows calculated drawdown in the upper aquifer. When entering a value in this field to calculate pumping rate

"B2, m" text box

Leaky factor for the upper aquifer

"k, m/day" text box

Hydraulic conductivity of bottom aquifer

"a, m^2/day" text box

Hydraulic diffusivity of bottom aquifer

"B, m" text box

Leaky factor for bottom aquifer

"m, m" text box

Bottom aquifer thickness

"r, m" text box

Distance from the pumping well to an observation well

"T, m^2/day" text box

Transmissivity of bottom aquifer

"S, --" text box

Storage coefficient of bottom aquifer

"Ss, 1/m" text box

Specific storage of bottom aquifer
