Influencing factors the rockwall retreat of flysch cliffs on the Slovenian coast

Abstract

This study identifies factors that affect the speed of rockwall retreat of flysch cliffs between Kane Point and Strunjan on the Slovenian coast. Individual factors were combined in a geographical information system with mapped recent erosion features. The results indicate the influence of individual factors on the formation of erosion rills, gullies, surfwave breaks, slumps, and rockfalls; that is, flysch coast retreat processes. Special attention is dedicated to the occurrence of major slope processes, specifically slumps and rockfalls, which are an important contributing factor in cliff retreat. The article also presents the rock-fall and slump risk of individual sections of the coast.
