The Neuman type curve for unconfined aquifers allows estimation of both horizontal and vertical hydraulic conductivity (14299 bytes) | |
 |
Infinite Extent supports distance-drawdown graphs for up to five observation wells. The distance drawdown graphs provides quantitative estimates of aquifer transmissivity, radius of influence of the pumping test, and a visual indication of horizontal anisotropy in the aquifer. (12704 bytes) | |

Theis Recovery Method (12197 bytes) | |
 |
Infinite Extent allows graphing or analysis of five wells simultaneously. Here is a semi-log plot of drawdown in three observation wells for the same pumping test. (16023 bytes) | |
