  • Shape of the nappe during free overfall from a rectangular channel with zero bed slope 

    Zachoval, Zbyněk; Böhm, Petr; Pařílková, Jana; Šafář, Robert; Šulc, Jan (Institute of Hydrology of the Slovak Academy of Sciences, Institute of Hydrodynamics of the Academy of Sciences of the Czech Republic, 2013-09-02)
    The paper deals with selected procedures used to calculate the shape of compact nappe during free overfall from a smooth horizontal channel with rectangular cross section. Calculated and measured water surface and velocity ...
  • A simple model for the estimation of the number of fatalities due to floods in central Europe 

    Brázdová, Miriam; Říha, Jaromír (Copernicus Publications, 2014-07-30)
    In this paper a model for the estimation of the number of potential fatalities is proposed based on data from 19 past floods in central Europe. First, the factors contributing to human losses during river floods are listed ...
  • Study of Dam-break Due to Overtopping of Four Small Dams in the Czech Republic 

    Alhasan, Zakaraya; Jandora, Jan; Říha, Jaromír (Mendel University in Brno, 2015-07-01)
    Dam-break due to overtopping is one of the most common types of embankment dam failures. During the floods in August 2002 in the Czech Republic, several small dams collapsed due to overtopping. In this paper, an analysis ...
  • Unsteady Flow and River Bed Stratification Mutual Impact on Scour at the Abutments 

    Gjunsburgs, Boriss; Pařílková, Jana (University of Split, 2020-04-08)
    The floods of different probability, sequence, frequency, duration, and the riverbed with different grain sizes, numbers, sequences, and thickness of the layers are one of the reasons for the bridge`s abutments failure ...
  • Zone of flow separation at the upstream edge of a rectangular broad-crested weir 

    Zachoval, Zbyněk; Mistrová, Ivana; Roušar, Ladislav; Šulc, Jan; Zubík, Pavel (Institute of Hydrology of the Slovak Academy of Sciences, Institute of Hydrodynamics of the Academy of Sciences of the Czech Republic, 2012-12-01)
    The paper deals with the determination of the basic characteristics of flow at the crest of a rectangular broad-crested weir and in detail with the characteristics of flow separation at the upstream edge of the weir crest. ...
