Gravitational slope failures are common phenomena involving all rock slopes, at various scales. It is widely accepted that different factors exert an influence on those gravitational process. Among these, structural heterogeneities (inherited from the geological history of the massif) and alteration/weathering process are of first order. However, t...

Abstract: In order to recover and restore the beach-dune system of the Remolar (700 m length and more than 100 m wide, 070N direction), a series of soft restoration measures were proposed in 2004. To evaluate these measures, after 10 years, a study of the morphology, sedimentology and vegetation of the ecosystem was carried out. The survey of topog...

The structure of loess-soil sequences of the North-Eastern Azov region was studied in coastal outcrops and boreholes within four key areas of the terraces of different age. Based on the positions of paleosols in geological sections of interfluve areas, the palaeotopography during interglacial epochs of the last 500 ka was reconstructed. The analysi...
