To estimate
aquifer parameters basing on aquifer test analysis, diagnostic
graphs are constructed. Basic types of diagnostic graphs available
in ANSDIMAT program are shown in the table below. For bounded and
semibounded conceptual schemes (and multi well pumping)
distancedrawdown and timedistance drawdown graphs are not
available.
For plotting
timedrawdown and timedistancedrawdown graphs the user must
select observation wells (Menu "Choose
> wells"). For
distancedrawdown graph – select wells and observation points (menu
"Choose
> Time"). If wells are
not selected, graphs are plotted for all available observation
wells. The distancedrawdown graphs is plotted for the last
measurement unless observation points are selected.
