Pumping Tests in Nonleaky Confined Aquifers

Combined analysis of drawdown and recovery data using Theis (1935) solution

Combined analysis of drawdown and recovery data from a constant-rate pumping test in a nonleaky confined aquifer using Theis (1935) type-curve solution (data from USBR 1995).

Agarwal recovery method using Theis (1935) solution

Analysis of data from recovery test with Agarwal method using Theis (1935) type-curve solution (data from USBR 1995).

Analysis of sinusoidal pumping test

Displacement measured during a sinusoidal variable-rate pumping test in which the rate varied through several cycles of extraction and injection (Rasmussen et al. 2003).

Analysis of multi-well pumping test in channel aquifer (strip aquifer) using AQTESOLV's automatic image well generation

Analysis of drawdown measured in pumped well and three observation wells during a constant-rate pumping test in a nonleaky confined buried channel (strip) aquifer near Estevan, Saskatchewan, Canada (Walton 1970).

Analysis of drawdown and recovery with derivative from single-well pumping test in nonleaky confined aquifer

Analysis of drawdown and recovery data with derivative from a constant-rate single-well pumping test in a nonleaky confined bedrock aquifer (Papadopulos and Cooper 1967). Early-time data show wellbore storage effect before derivative becomes constant (infinite-acting conditions). The low storage coefficient suggests well loss.

Forward solution with cyclic pumping conditions

Predictive simulation showing drawdown in the pumping well and two observation wells (r=500 and 2000 ft) under cyclic (intermittent) pumping conditions in a nonleaky confined aquifer.
