Landslides in the Lower Greensand escarpment in south Kent

Abstract The escarpment of the Lower Greensand in south and central Kent is extensively landslipped. The paper describes the landslips in general but concentrates on those parts of the escarpment which form the abandoned coastal cliffs, now protected from marine attack by Romney Marsh. In particular it considers the investigation of a set of landslips near Hythe, Kent, which form part of an extensive landslide complex re-activated at the time of the 1988 wet period. The rainfall patterns for the area are discussed and related to the landslide events. New insights into the nature of the historic damage to the third century fort known as Stutfall Castle are considered.Résumé Les reliefs des Lower Greensand, dans le sud et le centre du comté du Kent, présentent de nombreux glissements. L'article décrit ces glissements en général, et se concentre sur les parties de ces reliefs qui forment les anciennes falaises côtières, maintenant protégées de l'érosion marine par les marais de Romney. En particulier, sont présentés des travaux de recherche concernant une série de glissements près de Hythe (Kent) qui font partie d'une grande zone de glissements réactivés lors de la période humide de 1988. Les données pluviométriques de la région sont analysées et rapportées aux glissements de terrain réactivés à cette occasion. De nouvelles idées sur la nature des dommages subis historiquement par le fort du troisième siècle, connu sous le nom de Stutfall Castle, sont présentées.
