Identification and Mitigation of Subsidence in Karstic Areas with sustainable geotechnical structures: A Case Study in Gallur (Spain)

In various areas of the Ebro valley in Spain, including the region discussed here, the risk of sinkholes is becoming particularly severe, particularly impacting urban areas and roadways where land subsidence from karstic processes is common. However, knowledge of the area, its geological–geotechnica...
