Removal of barometric pressure effects and earth tides from observed water levels.

The effects of barometric pressure and earth tide changes are often observed in ground water level measurements. These disturbances can make aquifer test interpretation difficult by masking the small changes induced by aquifer testing at late times and great distances. A computer utility is now available that automatically removes the effects of barometric pressure and earth tides from water le...

Well Design to Reduce Barometric Pressure Effects on Water Level Data in Unconfined Aquifers

restrict communication to the atmosphere. As a result, gas pressures in the vadose zone will change more slowly Barometric pressure fluctuations may influence measured water and to a lesser extent than barometric pressure. Conlevels in wells where thick vadose zones or low permeability materials versely, gas pressure in an unsealed well will equilibrate overlie unconfined aquifers. Here, we pre...

Lunar and Solar Barometric Tides in Australia

The lunar semidiurnal barometric tide Lz and the solar 2 4 , 12-, and &hr. oscillations of the surface pressure have been determined for 10 stations in Australia and on adjacent islands. At Rabaul and Moresby L2 is considerably smaller than elsewhere in these latitudes. The characteristic annual variation of the phase-late high tide during the D season-is found a t most Australian stations. But...

Establishment of earth tides effect on water level fluctuations in an unconfined hard rock aquifer using spectral analysis

Short-interval water level measurements using automatic water level recorder in a deep well in an unconfined crystalline rock aquifer at the campus of NGRI, near Hyderabad shows a cyclic fluctuation in the water levels. The observed values clearly show the principal trend due to rainfall recharge. Spectral analysis was carried out to evaluate correlation of the cyclic fluctuation to the synthet...

Some Problems on the Analysis of the Earth Tides

The spectral structure of the earth tides which have been observed during one year by an Askania gravimeter at Kyoto, and that of the corresponding theoretical tides on a rigid earth, were compared to determine the tidal factor of gravity and the phase lag with a high precision. A band-pass filter that has dominant responses only for semidiurnal or diurnal frequencies was applied to both of the...
