Sinkholes are widespread in many countries of the world, in several geological and morphological settings, affecting distinct lithotypes either in the detrital cover sequences or in bedrock outcrops.
In particular, some phenomena develop in geomorphological context
characterized by plain areas and notable detrital coverages, either made of sediments or colluvial or residual terrains, thick even tens to hundreds of meters. In some cases, the genetic mechanisms are poorly understood; they can be quite complex and appear not directly connected with classical
karstic processes.
The recent urban development and the increasing need of spaces for infrastructures in areas potentially affected by sinkholes require a better comprehension in terms of related susceptibility, hazard and risk.
The session aims to stimulate the discussion on the state-of-the-art of the studies on the mentioned topic, with special regard to sinkholes in plain not-karstic areas. Analyses of genetic mechanisms, methodological examples of investigation, and case studies are welcome, as well as description of
techniques for evaluating susceptibility, hazard and risk.

Note: A selection of studies presented at this session will be considered for publication in a special issue of a relevant international journal.
