The proxydata in hydrology: Possible uses. The reconstruction of the flood magnitude data series in Prague in the period 1118 - 2002.
Elleder, Libor ; Hladný, Josef (advisor) ; Munzar, Jan (referee) ; Brázdil, Rudolf (referee)
2 Abstract The thesis aims to point to the importance of the proxydata, in particular their significance for hydrology and water management. The historical hydrology, the subject of which the proxydata are, offers the whole range of techniques for extrapolation of the knowledge on hydrological phenomena into the relatively distant past. The thesis includes the review of the scientific literature targeted in particular to the processes and history of the records of hydrometeorological phenomena, the origin of the historical hydrology, its methodology and potentialities. The author's own work focuses on the application of the techniques already in use and apart from that it presents the very new methodological approaches. This includes the reconstruction of the culmination discharges using the combination of several techniques, the reconstruction of the hydrograms of the historical floods, etc. The main goal has been to reconstruct the time series of estimated peak discharges in Prague for the period of 1118-2002. This meant to reassume the former results published in the form of the chronologies of interpreted and verified documentary sources. These were completed by the corrected Klementinum records of the water levels. Recently localized epigraphic sources have been utilized and the analysis of the...

Water mills, iron mills, saw mills, washboards and paper mills during the flash flood in summer 1714.
Elleder, L. ; Šírová, J. ; Munzar, Jan ; Ondráček, Stanislav ; Lopaur, M. ; Dragoun, Z.
The extraordinary flood disaster in the summer 1714 in the Sázava River, Svratka River, Loučná River and Chrudimka River catchments represents one of biggest known flash floods in the Czech flood history. The flood destroyed not only tens of houses, but also a number of water mills, iron mills and other outbuildings. It was also destroyed many ponds. This fact played an important role during the flood. This event significantly influenced the development of water mills and possibly also the development of a network of ponds in the affected area.

Documentation of flood events on Czech rivers at the end of the 18th and in the 19th century, based on the oldest hydrological measurements
Munzar, Jan ; Ondráček, Stanislav ; Elleder, L.
Disregarding the old flood marks, we can consider the beginning of hydrological measurements on Czech watercourses to be occasional observations made by prof. A. Strnad on the Vltava (Moldau) River in Prague in the 1780s where he watched the extreme water levels from his observatory in the Klementinum by using binoculars. The beginning of regular observations in our country is usually considered the measurement on the Vltava R. in Prague dated 1825, which is however somewhat disputable (as far as our knowledge goes, regular measurements are documented only two years later). Nevertheless, the authors succeeded in finding evidence about water level observations on the Odra River in Bohumín already from year 1820, which lasted respectable sixty years on the Austrian-Prussian section of the watercourse. The paper is focused namely on the analysis and evaluation of their half-forgotten results.

The Central-European record precipitation and floods in Central Europe at the end of July 1897
Munzar, Jan ; Ondráček, Stanislav ; Elleder, L.
In 2007 we have commemorated the 10th anniversary of the natural disaster in July 1997, which affected a number of countries in Central Europe. In the Czech Republic it was the "flood of the century". A certain analogy was an extreme event which was recorded exactly a hundred years ago, in the summer of 1897, i.e. already before 110 years. While the then hitherto records of multiday total precipitation amounts were broken in July 1997, the 1-day amount of 345.1 mm measured on the Nová Louka station in the Jizerské hory Mts. on 29 July 1897 was not beaten. It is therefore the Czech -and most likely also at least the Central-European- record until there days. The extreme rains in the summer of 1897 resulted in high water which affected a considerable part of Central Europe. In the territory of the today’s Czech Republic the floods occurred namely in the Upper Labe (Elbe) R. Basin.
