AQTESOLV
provides more features and solution methods for the interpretation of
recovery tests than any competing software! Unlike our competitors,
AQTESOLV
does not limit you to just a few solution methods for the analysis of
recovery tests. With
AQTESOLV,
you may use any pumping test solution to analyze recovery
data! |

| Combining the analysis of drawdown and recovery data provides a consistent
estimate of aquifer properties from the complete set of test data. |

AQTESOLV
features the powerful Agarwal method for the analysis of recovery
test data. Through a simple transformation of field data,
Agarwal (1980) devised a method of recovery test data analysis that allows one
to use the same type curves developed for drawdown data.
The Agarwal
method assumes that the total time of pumping exceeds the period of
recovery which is typically the case. |

AQTESOLV
includes traditional residual drawdown plots that you may use to analyze
recovery data. A residual drawdown plot displays s' versus t/t' where s'
is residual drawdown, t is time since pumping began and t' is time since
pumping stopped. One commonly uses the Theis (1935) residual drawdown
solution to match a straight line to recovery data on a residual drawdown
plot.

| In
AQTESOLV,
however, one may use any type curve solution for pumping tests to match recovery
data on a residual drawdown plot. |
