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
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.
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.
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.
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.
Artesian, water table, semi-artesian and anisotropic aquifers can
be dealt with using WELL as can constant flow, constant lowering,
step and upstream tests with one or several control piezometers
or with a single well with reading of the results being carried
out contemporaneously or at different times, under stationary or
program determines the characteristic parameters of the aquifer
both through direct analytical interpretation and through automatic
interpolation and the recognition of the best fit conditions through
abacus principles, starting from flow tests performed on both individual
wells and on well fields equipped with control piezometers.
output of the calculations is made up of explanatory graph, which
can be Cartesian, logarithmic or bi-logarithmic, depending on the
chosen explanatory method.
