The main objective is to characterize the origin of pathologies in buildings and other facilities, and of subsidence processes, and to identify their causative phenomena in the subsoil. This study involves the analysis of resolution, penetration characteristics and noise affecting GPR signals in urban areas. The analyzed case studies are located in the Central Ebro Basin (NE Spain), where the main hazards are related to mantled karst (solution of evaporites below alluvial deposits). The studied examples show that in areas affected by karst activity with medium to high subsidence rates, interpretation of GPR profiles allows defining collapses, subsidence, surficial repairs (either historical or recent) and underground cavities. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 1.296 2014 CONSTRUCTION & BUILDING TECHNOLOGY 19 / 59 = 0.322 2014 Q2 T1 ENGINEERING, CIVIL 43 / 125 = 0.344 2014 Q2 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 154 / 257 = 0.599 2014 Q3 T2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Casas Sainz, Antonio María Pocoví Juan, Andrés Gil Garbi, Héctor Calvín, Pablo (orcid)0000-0002-4485-2139 2000 428 Universidad de Zaragoza Dpto.
