In this book a dell, a characteristic relief form in Slovenian dolomite regions, is described. A dell is a trough-shaped valley or a flat floored small valley on dolomite areas.The chapter about basic characteristics of dolomite relief and basic characteristics of trough-shaped valleys is followed by extensive chapter about morphological characteristics of a trough-shaped valleys, with special regard to dell longitudinal section analysis. Based on that the morphological typology of trough-shaped valleys is stated. The book also deals with the dell genesis. Trough-shaped valleys are polygenetic convergent relief forms as they may exist on different bedrock and are shaped by different geomorphic processes. Recent intensive geomorphic processes have been proved by qualitative (geomorphological mapping) and quantitative (absolute dating) methods. The assumption of the importance of recent geomorphic processes was confirmed by geoelectrical measurements as well.

V knjigi je opisana značilna reliefna oblika dolomitnega reliefa v Sloveniji, imenovana dolec ali dolek. Površje na dolomitnih kamninah je lep primer součinkovanja denudacijskih in fluvialnih geomorfnih procesov, saj ga spreminjata kraška korozija in denudacija, ki je posledica površinskega in deloma podpovršinskega odtekanja padavinske vode. Pri nastajanju dolcev sodelujeta obe omenjeni skupini geomorfnih procesov, zato so dolci poligenetska reliefna oblika, ki nastaja in se oblikuje tudi v sodobnosti. Uvodnemu poglavju o temeljnih značilnostih površja na dolomitu sledi oris morfoloških značilnosti dolca. Osrednji del knjiga je posvečen njegovi genezi. Opisani so rezultati morfometričnih in genetskih raziskav, predvsem geomorfološkega kartiranja, radioogljikovega datiranja in meritev električne upornosti gradiva.
