Documentation of a spreadsheet for time-series analysis and drawdown estimation
Keith J. Halford
2006, Scientific Investigations Report 2006-5024
Drawdowns during aquifer tests can be obscured by barometric pressure changes, earth tides, regional pumping, and recharge events in the water-level record. These stresses can create water-level fluctuations that should be removed from observed water levels prior to estimating drawdowns. Simple models have been developed for estimating unpumped water levels...
