dc.description.abstractThe article is focused on the historical shortening of the river network as one of the important factors influencing the Course and consequences of the foods. The river network shortening is studied at the example of the core zone of the extreme flood in August 2002 - in the Otava river basin. The solution is based on analysis of various data sources - historical maps covering the time period of 150 years as well on the current digital cartographic products. Using (HS analysis there was derived information on spatial distribution of stream shortening intensity as well as on the dynamics of the rectification process in time. The most intensive rectification up to 40% of the former river length is observed on stream segments situated in the agricultural landscape in lowlands. Major changes on main streams in the Otava river basin were made in the 1 half of the 20th century - the intensive agricultural practices in I 970's and I 980's thus here affected predominantly the small streams. However the river shortening intensity in the study area is in some regions high the ana1ysis did dot prove the stream rectification to be the leading factor of severe consequences of extreme flood in August 2002en
