Reliability check of flash-flood in Central Bohemia on May 25, 1872

Original language description

The flash flood in Central Bohemia from May 25, 1872 belongs among the most disastrous events ever recorded on the territory of the Czech Republic. An extreme torrential rain affected the area of approximately 2,000 km2. Two incidental historical measurements reported precipitation amounts higher than 200 mm during 3–8 hours, however, these remained unverified. The peak water levels of subsequent flood have not been exceeded since at the Berounka River and its tributaries (including disastrous 2002 flood).The1872 flood caused tremendous damages on fishponds, houses, infrastructures and lead to the temporary collapse of transportation especially due to complete destruction of railways and bridges. Among others, the flood caused a dam breach of the Mladotice reservoir that hold likely more than 5 mil m3 of water and with a delay of 2–3 days triggered a massive landslide and dammed the Mladotický creek and created new Odlezelské Lake. Based on various reports the number of fatalities reached 240–300. This flood motivated at least 3 contemporary (1872 – 1875) scientific papers. It also initiated, together with the drought in 1874, the establishment of the Hydrological Service of Czech Kingdom in 1875. The intensity and spatial extent of this flood induced by torrential rain was extraordinary in the conditions of Central Europe. The only known comparable flood event was the flood from July 31st 1714 at the Sázava River catchment. Due to the fact that the systematic hydrological and meteorological observations in the area started in 1883, the flood analysis is based on interpretation of documentary sources. The aim of our study is to explain in more detail the development of the 1872 flood, and especially to provide the interpretation of available reports (newspapers and chronicles) from the hydrological perspective. We completed earlier hydraulic estimation of peak discharges in selected profiles based on flood marks along the Berounka River. Furthermore, hydrological modelling system Agualog was used to check the reliability of reported precipitation using the estimated peak discharges of the Berounka River in the Beroun town and the Vltava River in Prague. We propose the alternative reconstruction of peak flow of the Vltava River in Prague in association of the second flood maximum represented by the reported increase of the water level by 2 to 3 m in few minutes with the dam breach of Mladotice reservoir. We discuss prevailing importance of the 1872 flood for current flood protection planning and design, including Prague flood protection system of mobile flood walls. The major problem in this respect is a short time span of 22 hours between the start of causative rainfall and the flood peak in Prague which provides insufficient time for the construction of all mobile flood protection measures.
