Interpretation of the data relevant to the pumping tests.

Through these tests, it is possible to calculate the main hydrodynamic parameters of the aquifer, such as the specific flow, the coefficient of permeability, the transmissibility, ad the coefficient of storage.

The test can be executed both on single wells and on testing stations.

Description

PUMPING TESTS

Software for the interpretation of data relevant to pumping tests.

STATE OF EQUILIBRIUM FLOW

It is based on a theory (by Dupuit) constructed on the hypotheses which tend to simplify phenomenology.

Low equilibrium-state or steady-state flow conditions (flow changes only occur in space and not in time) are obtained when feeding exactly compensates for the outflow.

STATE OF NON-EQUILIBRIUM FLOW

Outflow in a state of non-equilibrium or transient-state flow is a theory expounded by Theis, who considers the occurrence of flow changes in space and time.

According to this theory, the surface of piezometric depression around a well with a constant flow does not tend to be stable but spreads indefinitely at decreasing speed.

Testing stations are made up of a well called a pilot, and one or more piezometers must be placed within the radius of action of the well. W.T.A. allows considering the water flow both in steady-state and transient-state flow conditions.
