Estudio de la subsidencia del terreno producida por la explotación de acuíferos mediante datos de Interferometría Radar Satélite

Abstract

This thesis proposes a methodology to analyze subsidence due to groundwater extraction, improving the current knowledge and the characterization of aquifersystems, also allowing to evaluate the impact of subsidence over urban structures and infrastructures. This thesis is divided in three parts: (i) description of the methodology; (ii) results obtained in four study areas; (iii) and conclusions.The methodology consists of four sections: (i) an integrated system to monitor aquifer-systems; (ii) methods of data analysis and empirical modelling; (iii) hydrogeological and geotechnical modelling; (iv) evaluation of the potential impact of subsidence over buildings and infrastructures. X Finally, in Pistoia city case study (iv) results show that the joint analysis of monitoring data with geotechnical data permits to identify vulnerable urban areas where subsidence could generate damages over structures and infrastructures.Overall, these results demonstrate that the proposed methodology improves the knowledge of aquifer-systems affected by groundwater over-pumping and helps to achieve a sustainable management of groundwater resources in over stressed basins.

Analysis of Deformation Dynamics in Guatemala City Metropolitan Area Using Persistent Scatterer Interferometry

“…Moreover, InSAR has proved to be a valuable tool for urban development strategies aimed at improving sustainability and safety in urban environments [13][14][15][16][17][18][19][20][21]. Additionally, InSAR has also been used to analyze urban deformation caused by the exploitation of groundwater [1,[22][23][24][25]. For instance, Mexico City is one of the fastest sinking metropolises in the world, with a displacement rate of up to 2.5 cm/month.…”
