Water level observations made during a aquifer tests are susceptible to distortions
due to the influence of ambient temperature and ambient pressure and local
gravitational acceleration. These distortions can be significant in aquifer test cases
where interference due to pumping effects are small, because barometric
pressure effects can make up a large proportion of the total observed water level
fluctuations It is therefore important to consider and correct for effects of
barometric pressure changes, temperature changes and location changes when
analyzing aquifer test water level data.
We have corrected all 3 main elements of distortion possibilities. These 3
possibilities are taken care with these innovative concepts and during the
product development.
- Gravitational Acceleration Location
The variation in ambient pressure changes the depth of water column. The
variation of ambient pressure with respect to temperature and altitude can be
seen as follows;

Borewell water temperature changes with ambient temperature. The effect can
be seen from the following diagram;
Temperature Profile with Respect to Ambient Temperature at Ground
The density of the water is a strong function of water temperature, the variation
can be seen from the table. The correction while calculating the water column is
must for accurate calculations.

The local gravity is dependent on several factors such as latitude, height above
sea-level, local geological density, etc.The gravity is important factor when Water
Column is calculated because gravity directly relates the mass of water column.
Though the default value of gravity is 9.80665 ms-2 which is standard gravity, the
variation can be observed as follows;
The formulas used by this calculator are based on the International Gravity Formula 1980 (IGF) which determines the gravity from the position of latitude, and the Free Air Correction (FAC) which corrects for height above sea level.
IGF = 9.780327 (1 + 0.0053024sin2Φ – 0.0000058sin22Φ)
FAC = -3.086 x 10-6 x h
g = IGF + FAC
