  • Discussion on the Safety Factors of Slopes Recommended for Small Dams 

    Vrubel, Jan; Říha, Jaromír (Mendel University Press, 2017-03-06)
    The design and assessment of the slope stability of small embankment dams is usually not carried out using slope stability calculations but rather by the comparison of proposed or existing dam slopes with those recommended ...
  • Earth-Fill Dam Monitored by EIS Method during Application of Nutrient Aqueous Solution used in BioSealing Method 

    Pařílková, Jana; Gjunsburgs, Boriss; Zachoval, Zbyněk; Veselý, Jaroslav; Műnsterová, Zuzana (IOP Publishing, 2017-10-25)
    The paper gives short information about the results of monitoring the electrical properties of an earth-fill dam during the application of a nutrient aqueous solution used in the method BioSealing. Monitoring is carried ...
  • 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 ...
  • Discharge coefficient of a rectangular sharp-edged broad-crested weir 

    Zachoval, Zbyněk; Knéblová, Michaela; Roušar, Ladislav; Rumann, Ján; Šulc, Jan (Institute of Hydrology of the Slovak Academy of Sciences, Institute of Hydrodynamics of the Academy of Sciences of the Czech Republic, 2014-04-01)
    This paper is concerned with the determination of the relationship for the calculation of the discharge coefficient at free overflow over a rectangular sharp-edged broad-crested weir without lateral contraction. The ...
  • 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. ...
  • Flow characteristics at trapezoidal broad-crested side weir 

    Říha, Jaromír; Zachoval, Zbyněk (Institute of Hydrology of the Slovak Academy of Sciences and the Institute of Hydrodynamics of the Academy of Sciences of the Czech Republic, 2015-04-01)
    Broad-crested side weirs have been the subject of numerous hydraulic studies; however, the flow field at the weir crest and in front of the weir in the approach channel still has not been fully described. Also, the discharge ...
  • Assessment of empirical formulae for determining the hydraulic conductivity of glass beads 

    Říha, Jaromír; Petrula, Lubomír; Hala, Mario; Alhasan, Zakaraya (De Gruyter Open, 2018-08-14)
    Empirical formulae are often used in practice to quickly and cheaply determine the hydraulic conductivity of soil. Numerous relations based on dimensional analysis and experimental measurements have been published for the ...
  • Evaluation of groundwater contamination in former military airport area 

    Petrula, Lubomír; Říha, Jaromír; Julínek, Tomáš (Croatian Association of Civil Engineers, 2018-05-10)
    The analysis of groundwater contamination at the former military airport, due to fuel tanks leakage and other accidental spills, mainly involving polycyclic aromatic hydrocarbons (PAH), is presented in the paper. It was ...
  • Numerical and experimental investigation of swirling flow in a conical diffuser 

    Štefan, David; Zubík, Pavel; Hudec, Martin; Rudolf, Pavel (EDP Sciences, 2014-11-18)
    The decelerated swirling flow often breaks down into helical structure which is unstable and causes unsteady velocity and pressure fields. The numerical and experimental investigation of this flow pattern is carried out ...
