Remote sensing to assess the risk for cultural heritage: forecasting potential collapses due to rainfall in historic fortifications

Purpose Heavy rainfall is one of the main causes degradation historic rammed Earth architecture. For this reason, ensuring conservation thereof entails understanding factors involved in these risk situations. The purpose study to research three past events which caused damage and collapse fortifications Andalusia order analyse whether it possible prevent similar situations from occurring future. Design/methodology/approach case studies analysed are located south Spain occurred between 2017 2021. hazard presented by within context has been obtained Art-Risk 3.0 (Registration No. 201999906530090). vulnerability structures assessed with 1 model. To characterise strength, duration, intensity precipitation events, a workflow for statistical use GPM GSMaP satellite resources designed, validated, tested. strength winds evaluated data ground-based weather stations. Findings very Regarding analysed, although they areas torrential hazard, was non-intense that did not exceed 5 mm/hour. continuation several days poor state walls seem be triggered collapses fundamentally affected restoration mortars. Originality/value A applied analysis presented, validates large-scale images present monitoring heritage structure due rain.
