The reconstruction of the channel avulsion of the Berounka River from Zbraslav to Lahovice by using historical data
Abstract
The analysis of historical data may provide valuable information for solution of the evolution of the river in historical time. The avulsion of the river channel between Zbraslav and Lahovice in the southern part of Prague in 19th century was solved by this historical-geographical analysis. The avulsion was lasting 75 years (from formation of the initial avulsive channel to deactivation of the old channel). Floods, especially ice-floods, had the main influence on the avulsive evolution. The main avulsive events happened in periods of increased flood frequency (1796-1799; 1824-1830). The initiation of the avulsion was influenced probably by the topography of the floodplain in confluence area of the Berounka River and Vltava River.
