Data processing for oscillatory pumping tests
Characterizing the subsurface is important for many hydrogeologic projects such as site remediation and groundwater resource exploration. Methods based on the analysis of conventional pumping tests have the notable disadvantage that at a certain distance, the signal is small relative to the noise due to the effects of recharge, pumping in neighboring wells, change in the level or adjacent strea...
متن کاملAnalytical and Semi-Analytical Tools for the Design of Oscillatory Pumping Tests.
Oscillatory pumping tests-in which flow is varied in a periodic fashion-provide a method for understanding aquifer heterogeneity that is complementary to strategies such as slug testing and constant-rate pumping tests. During oscillatory testing, pressure data collected at non-pumping wells can be processed to extract metrics, such as signal amplitude and phase lag, from a time series. These me...

متن کاملNew innovation method modified for analyzing aquifer test data of pumping and recovery tests
This work can be considered as an effort to recognize the relationships between the drawdown and recovery data for the aquifer system, and instead of separated two graphs including Cooper – Jacob for the pumping test and Theis recovery straight line methods, Elhag (2014) innovational simplified solution agrees with more complicated solutions, and useful for determine aquifer parameter values in...
متن کاملVariable-Rate Pumping Tests for Radially Symmetric Nonuniform Aquifers
Conventional pumping test methodology is of limited effectiveness for defining the spatial distribution of aquifer properties because of the nonuniqueness of the parameter estimates. Sensitivity analysis can be used to develop a pumping test procedure that significantly decreases the uncertainty associated with the estimated parameters. This approach employs systematic variations in pumpage rat...
