Abstract

The Paphos District has been described as one of the most landslide-prone areas of Cyprus, with landslides impacting villages, roads and other infrastructure. With increasing levels of development and investment in infrastructure, Cypriot authorities are investigating ways to assess landslide susceptibility, hazard and risk for planning purposes. A 2-year project has catalogued over 1,840 landslides, investigated the spatial distribution of key landslide attributes, and used the results to develop maps of landslide susceptibility across large areas of the Paphos District. To gain a better understanding of the materials and failure mechanisms involved, 20 of these landslides were selected for further study, including engineering geological mapping, ground investigation, laboratory testing, development of ground models and slope stability analysis at specific locations. The results enabled soil parameters to be reviewed, thus strengthening the interpretations derived from field observations. The use of the mapping outputs is discussed in terms of planning and engineering applications and recommendations are made for strengthening and expanding the landslide database.

Résumé

Le District de Paphos a été décrit comme l’une des régions de Chypre les plus sujettes aux glissements de terrain, avec des glissements menaçant des villages, des routes et d’autres infrastructures. Avec un développement croissant et les dépenses correspondantes dans les infrastructures, les autorités chypriotes étudient les moyens d’évaluer la sensibilité aux glissements de terrain et les risques dans un contexte d’aménagement du territoire. Un projet de deux ans a permis de répertorier plus de 1,840 glissements de terrain, d’étudier les caractéristiques majeures de ces glissements et d’établir des cartes de susceptibilité aux glissements de terrain sur de vastes zones du District de Paphos. Afin d’avoir une meilleure compréhension des matériaux et des mécanismes de rupture associés, une vingtaine de ces glissements de terrain ont été sélectionnés pour une étude plus approfondie, avec une cartographie géologique, des études de terrain, des essais de laboratoire, des modélisations et des études de stabilité en des zones précises. Les résultats ont permis de revoir les paramètres géotechniques pris en compte et de consolider les interprétations issues des observations de terrain. Les résultats cartographiques issus de ce projet sont discutés en termes d’aménagement du territoire et des recommandations sont faites pour renforcer et élargir la base de données des glissements de terrain.
