Application surface of CPT, an advanced DInSAR displacement near Itoiz dam, Navarra, Spain
Itoiz reservoir is located in Navarra, northern Spain, being a newly constructed gravity dam that stores the water from the Irati and the Urrobi rivers. The dam has a total height of 121 m, a total length of 525 m and a maximum water storage volume of 410 hm3. The aim of this work is to study the surface displacement field during the impoundment of the Itoiz water reservoir. Orbital SAR Differential
Interferometry (DInSAR) techniques have been proven to be a useful and powerful tool in tectonic areas for surveying subtle surface deformations over several years related to geodynamic phenomena. An advanced DInSAR observation technique, Coherent Pixel Technique (CPT), has been applied to study the existence of deformation in the dam area in order to obtain mean velocities and time series of
deformation.
We have studied the applicability of this technique to study the surface displacement field during the impoundment of the Itoiz water reservoir. Specifically, we focus on
the analysis of the stability of the left slope of the reservoir.
We have used ERS and ENVISAT descending and ascending images concerning to the 1992-2008 and 2003-2008 periods respectively. We compare the observation results with the displacement induced by water loading obtained using a theoretical model
On the applicability of an advanced DInSAR techniques near Itoiz and Yesa reservoirs, Navarra, Spain
In this paper we show the applicability of orbital Synthetic Aperture Radar (SAR) Differential Interferometry (DInSAR) with multiple images for terrain deformation episodes monitoring. This paper is focused on the Coherent Pixels Technique (CPT). This technique has been tested with ERS SAR and ENVISAT ASAR data for the period 1992-2008 from
The Itoiz and Yesa reservoirs. These ones, located in Navarra, northern Spain, are constructed gravity dams
that stores the water from the Irati and the Urrobi rivers,
and the Aragón river respectively. The results has been
compared with theoretical results obtained using an
analytical model

Application of TerraSAR-X data to the monitoring of urban subsidence in the city of Murcia
This paper presents an analysis of the performance of TerraSAR-X for subsidence monitoring in urban areas. The city of Murcia has been selected as a test-site due to its high deformation rate and the set of extensometers deployed along the city that provide validation data. The obtained
results have been compared with those obtained from ERS/ENVISAT data belonging to the same period and validated with the in-situ measurements
