CASE STUDY: EXPLOITATION OF GROUND WATER IN SPAIN (ESA)
Objective of the project Detection and mapping of areas affected
by uplift and subsidence movements due to exploitation of
aquifers in Murcia City (South-East of Spain) and surroundings.
The objective of the project was to locate and quantify with
precision subsidence phenomena. Analysis and results The period
of study has been: 1995-2006. Subsidence measurements have been
detected up to 3 cm in Murcia City and up to 11 cm in the whole
Vega Media del Segura river area. The high precision measurement
of results have been confirmed and validated by in-situ
measurements (extensometers). InSAR results show up to 11 cm of
annual subsidence. These measurements coincide with the results
of deformation measured by extensometers.
