The hydrological quality of an aquifer system is evaluated by means of two parameters: its capabilities to transmit water (transmissivity, T) and to store water (storage coefficient, S). In this work, a method based on temporal data of the surface subsidence is employed to calculate storage coefficients (S) and transmissivities (T) of the Vega Media of the Segura river aquifer-system. Subsidence data are obtained by means of differential SAR interferometry. The retrieved values of S for all available wells vary from 3.2 times 10 -5 to 1.9 times 10 -3 m/m. For the only well where water flow is available, a T value of 0.302 m 2 /day is estimated. First results show a reasonable agreement between data calculated with this technique and other acquired by means of in situ measurements.
