This small software can simulate any pumping up to 5 wells

You can select:

· Area size

· Well(s) location, distance (meter) (r)

· Coefficient of storage in % (S)

· Coefficient of transmissivity (m²/s) (T)

· Pumping rate (m³/h) (Q)

Result is displayed in map or 3D view.

You can record a text file  X, Y, Z for export to a contouring like SURFER

The Cooper & Jacob (1946) formula is used for drawdown computation

s= ( 0.183 * Q )/ T  * Log (( 2.25 * T * t ) / ( r * r * S)

If interested ask for VB6 code

If you have SURFER of Golden Software, you can export result and have a better display with numerous options.
