Title: Review of the manuscript se-2018-62, "Geomechanical modelling of sinkhole development using Distinct Elements: Model verification for a single void space and application to the Dead Sea area", by Djamil Al-Halbouni et al.
Abstract: This manuscript presents a numerical study of Discrete Element Models set to simulate the formation of sinkholes in different types of rocks, and compare the observed craters with those observed at the Ghor al-Haditha sinkhole site, close to the Dead Sea.The shape of the craters formed in series of simulations, with different types of rocks, depth and size of the underground cavity responsible for the sinkhole formation, is compared with Digital Elevation Models reconstructed by Stereophotogrammetry from field data.The study is well introduced and well presented.The data is solid, both for the nu-
