Vliv říční nivy na hydrologický režim horní Lužnice

Abstract

The aim of this study is an evaluation of the hydrological regime of the upper part of the Lužnice River basin with respect to anthropogenic modifications. The Lužnice River is located in the south of Czechia. A larger part of the river exhibits a low intensity of modification - meandering stream with many pools and oxbow lakes in the floodplain where a safe retention of water during the flood event remains possible. The main part of the study concentrates on the hydrological regime. The methodology is based on statistical evaluation of a long-time data series from the Pilař water gauging station. Flood events and dry periods were analysed during the past 46 years. Discharge measurements (conducted by the Faculty of Science, Department of Physical Geography and Geoecology) are used for recent flood evaluations.
