Pprospecting and Estimation Of Undeground Fresh Water Resources with the use of Geothermal and Remotely Sensed Data

The research of fresh water supplies, especially in drought areas is very important task
nowadays. Despite this fact, there’s no general method of realization such works.
In many cases we still rely on single process decision.

Based on remotely sensing data we have developed a unique technique which allows
to carry out following tasks:

PROSPECTION OF SUBMARINE SOURCES OF UNDERGROUND
FRESHWATER AND ESTIMATION OF THEIR DEBITS
AQUIFER MODELLING

The solution of both above-mentioned tasks is based on construction of complex
mathematical models of energy-mass exchange in hydrosphere and lithosphere. The method
is based on complex mathematical and spatial modelling with the use of:

hydro-geological and structural recognition of an area;
structural analysis of remotely sensed multispectral data;
analysis of remotely sensed thermal images.

Hydrogeological information on the aquifers should include, i.a., porosity, permeability,
specific yield of aquifer recharge, possible places of recharge of freshwaters
in a sea pool, and should be based on data obtained from wells.

Structural analysis of space images is used for allocation and study of geological
structures, which reflect distribution of underground waterbearing strata.
Both, multispectral and thermal images are used for determining infiltration zones
and areas of increased soil humidity.

The results of implemented works definitely proved that the offered methods can
be successfully used at the stage of prospecting of sources of fresh waters and at the
stage of their investigation and operation.
