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)
The simple Theis type curve. (14915 bytes)
The Walton type curve method for leaky aquifers (16841 bytes)
