O článku:

A geomorphological network – a network of valleys and inter-valley ridges develops in changing morphostructural and morphoclimatic conditions. It is transforming. A new network replaces the old one. Thanks to the gradual character of this process it is possible to identify several generations of networks in relief. Their analysis may bring some valuable pieces of knowledge about the geomorphological development of a certain territory. In basins of north-eastern Slovakia (the mountainous part of the River Laborec and small partial basins in the Poloniny Mts. located in the basin of the River Uh) texture properties of valley networks, barrier effect of basins, isobasite map and relevant properties of the geological structures were analysed. The results confirmed that the territory in question has been subject to a complicated morphostructural development in the Neogene and the Quaternary, which manifested itself in a pronounced transformation of the geomorphological networks, as well as in other ways. The old network formed in the Palaeogene corresponded to the arrangement of fold structural elements of the outer flysch belt. A new network with a considerably different composition of valleys and ridges was formed in the changed morphostructural conditions. Transformation where the river piracy has played a multiple role has reached the stage in which the new network prevails but segments of the old network are still recognizable. This transformation was caused by three morphostructural agents: subsidence of the territory of what is today the East Slovakian Lowland, developments in the neighbouring basin of the River Ondava and the rise of a barrier in the form of the Neogene stratovolcanos, the Vihorlatské Mts.
