Zatrepne doline so zna?ilna povr?inska reliefna oblika izvirnega kontaktnega krasa. V ?lanku so opisani zna?ilni primeri zatrepnih dolin v Sloveniji. Dosedanje raziskave so se po ve?ini ukvarjale zgolj z opredelitvijo termina, redke pa so bile ?tudije, ki so obravnavale njihove geomorfolo?ke zna?ilnosti. Z obse?nim terenskim delom smo opredelili morfografske in morfometri?ne zna?ilnosti zatrepnih dolin. Izvedli smo njihovo morfogenetsko interpretacijo, ki se delno opira na obstoje?o literaturo, predvsem pa na sintezo geolo?kih, hidrolo?kih in speleolo?kih podatkov ter izsledkov s terena. Ugotovili smo, da se zatrepne doline med seboj mo?no razlikujejo v oblikovanosti. Na njihov razvoj vplivajo kamninska sestava, prelomi, vodotoki, oblikovanost jamskih sistemov v zaledju zatrepnih dolin in raven povr?inske reliefne oblike, v katero se izteka zatrepna dolina.Pocket valleys are typical landforms in the outflow part of contact karst. Examples of pocket valleys were identified and geomorphologicaly examined in detail. Previous studies of pocket valleys have mostly considered the definition of pocket valleys, whereas geomorphological studies have been very rare. The morphographic and morphometric characteristics of pocket valleys were defined through detailed geomorphological examination. Morphogenetic interpretations of pocket valleys were made based in part on existing literature, but mostly based on a synthesis of geological, hydrological, and speleological data with fieldwork results. It was confirmed that the development of pocket valleys is influenced by lithology, geological structure, characteristics of water flow discharge, formation of cave systems in the rim of pocket valley, and the level of regional surface landforms that pocket valleys are located above.
