  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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. ...
