Techniques of water-resources investigations of the united-states geological survey, 8. Chapter A1 : methods of measuring water levels in deep wells [texte imprimé] / Garber, M. S. ; Koopnan, F. C. . - United-States government printing office . - United-States government printing office, 1968. ISSN : CI-07727 Accurate measurement of water levels deeper than 1, 000 feet in weeks requires specialized equipement. Corrections for stretch and thermal expasion of measuring tapes must be considered, and other measuring devices must be calibrated periodically. Borehole deviation corrections also must be made. Devices for recording fluctuation of fluid level usually require mechanical modification for use at these depths. A multichannel recording device utilizing pressure transducers has been constructed. This device was originally designed to record aquifer response to nearly underground nuclear explosions but can also be used for recording data from multiwell pumping tests.
