O článku:
The aim of this study is to analyse the changes in the morphology and riverine landscape or land cover of the Váh River, induced by human activity in the 20th Century. The Váh River is an exemplary case of human modification of the fluvial system (damming, by-passing, channel straightening, etc.). The Váh River fluvial system has been analysed in three ways. The planform changes have been evaluated for the whole river course, based on the topographic data displayed on the maps of the Third Military Mapping of the Austro-Hungarian Empire (reflecting the years 1869–1887) and spatial data on the national level of Slovakia – ZB GIS (2005–2008). The bankline movements, channel width and channel bars changes have been analysed in detailed scale, comparing two reaches (Púchov – Trenčín and Piešťany – Sereď). These analyses were based on the data obtained from the aerial photos and orthophotomaps (1949, 1985 and 2003). The land cover structures changes have also been analysed for one reach. The results have proven strong anthropogenic transformation of the Váh River fluvial system, especially channel narrowing, side channels and channel bars vanishing, forest riparian vegetation expansion and reduction of valuable aquatic and semi-aquatic habitats.
