This program is used to determine some of the most important hydrogeological parameters (transmissivity and storage coefficient) of unconfined, confined and semi-confined aquifers through the interpretation of well tests.
The numerous calculation methods contained in the program allow the operator to select the most suitable methods for the aquifer and for the type of test performed.
Tests are normally performed under transitory flow conditions and only, in a few cases, under stationary flow conditions; one therefore normally works with constant flow rates and only rarely with variable flow rates in steps.
WELL makes use of several methods to interpret the tests performed under transitory flow and constant rates while only a few methods are implemented for tests under stationary flows.
The methods that are available have been subdivided according to the type of aquifer; if it is not sure what type of aquifer is being examined, it is possible to use methods that utilise logarithmic diagrams that are able to give indications on the aquifer, on the basis of the type of curve that is obtained.
