The dialog window "Recharge" is used to calculate impact of recharge on water levels during aquifer tests.
The window is opened by "File > Hydrogeologist workbench > Groundwater mound > Recharge".
"Recharge" dialog box
Explanatory table
"ε, m/day" text box |
Time-constant recharge rate, m/day |
"Q, m^3/day" text box |
Constant pumping rate of a test well, m3/day |
"k, m/day" text box |
Hydraulic conductivity of an aquifer, m/day. After entering this value, transmissivity is automatically recalculated |
"Sy, –" text box |
Specific yield of an aquifer (dimensionless). After entering this value, hydraulic diffusivity is automatically recalculated |
"m, m" text box |
Thickness of an aquifer, m. After entering this value, transmissivity is automatically recalculated |
"T, m^2/day" text box |
Information field displaying the transmissivity of the aquifer. Entering a value in this field recalculates hydraulic conductivity |
"a, m^2/day" text box |
Information field to display hydraulic diffusivity. Entering a value in this field recalculates the specific yield |
"t, day" text box |
Time (days) at which change of drawdown is calculated |
"Time of maximum drawdown" text box |
Information field to display the time (in days) after which recovery starts
|
"Decrease drawdown" text box |
Information field - shows how drawdown decreases at specific times
