      Required control parameters:
        |NHRU|
        |KG|
  
      Required input sequence:
        |Nied|
  
      Calculated flux sequence:
        |NKor|
  
      Basic equation:
        :math:`NKor = KG \\cdot Nied`
  
      Example:
  
          >>> from hydpy.models.lland import *
          >>> parameterstep('1d')
          >>> nhru(3)
          >>> kg(0.8, 1.0, 1.2)
          >>> inputs.nied = 10.0
          >>> model.calc_nkor_v1()
          >>> fluxes.nkor
          nkor(8.0, 10.0, 12.0)
