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.
