Scripts for calculating recharge

[G. Zacharioudakis]

We are interested inn setting up a GIS model calculating the 
recharge into an aquifer using the Soil Moisture deficit approach.
Has anybody written a shell script for doing it on a temporal basis.
(for each time step which is the least one day!)
Cheers for any help
