Extreme terrain deformation in an uncontrolled waste disposal plant in Andros Island

Περίληψη

Uncontrolled waste disposal plants besides the environmental impact intensively alter the morphology setting of the sites and sometimes raise serious hazard issues. When developed in anthropogenic cavities (e.g. old quarries) they are considered as part of the restoration procedure and, excluding the environmental impact, they cause bearable alterations to the already damaged relief. On the contrary, when installed in natural cavities (e.g. stream valleys) their impact multiplies and, besides the terrain alteration, issues related with the impact on the hydrographic network and the stability of the waste disposal plant`s slopes raise. The current study aims to investigate the factors that mostly influenced the manifestation of a failure, an extreme terrain deformation that occurred after an intense rainfall episode at an uncontrolled waste disposal plant in the island of Andros, Greece.
