The formation of epigenetic gorges depends upon the competition between the resistance to transport, strength and roughness of valley-filling sediments and a river's ability to sculpt and incise bedrock. The AA. begin by introducing conceptual
models for the formation of epigenic gorges in relation to landslides and fluvial aggradation. They support these models and highlight the prevalence of epigenetic gorges in actively incising landscapes by discussing examples from around the world
, in rivers that drain the eastern margin of the Tibetan plateau, Peruvian Andes, Colorado Plateau and North Island of New Zealand. Motivated by these examples, they discuss the dynamics involved in epigenetic gorge formation, as well as their significance
Le Haut pays du Nord de l’Ethiopie possède un environnement fragile caractérisé par des pentes gorgées d’eau, des pluies abondantes et une végétation éparse. Aussi la topographie, la couverture du sol et la lithologie expliquent une grande partie
, because, between the Vuzenica-Radlje basin and Fala, the Drava epigenetically deepened its gorge into the marginal range of Kobansko. Modest plateaus on the ridge of the Pohorje originate from the time when the base level maintained a cover of the so
