Structure Transformations

The next structure transformations are available:

  • crumpWeir: Converts stage to discharge.
  • crumpWeirBackwater: Converts stage to discharge.
  • flatVWeir: Converts stage to discharge.
  • flatVWeirBackwater: Converts stage to discharge.
  • generalWeirFixedHeight: General weir function which has a fixed height. The height is configured in the coefficientset.
  • generalWeirVariableHeight: General weir function which has a variable height. The height is one of the inputvariables.
  • pumpFixedDischarge: Calculates discharge of a pump, using a fixed discharge when the pump is on. The fixed discharge is equal to the capacity of the pump and is defined in a coefficientSet.
  • pumpHeadDischargeTable: Calculates discharge of a pump. When the pump is on, then the discharge equals the capacity of the pump. The capacity of the pump depends on the head. The discharges for different heads are defined in a table in a coefficientSet.
  • pumpSpeedDischargeTable: Calculates discharge of a speed-controlled pump with a fixed capacity. When the pump is on, then the discharge of the pump depends only on the speed. The discharges for different speeds are defined in a table in a coefficientSet.
  • pumpSpeedHeadDischargeTable: Calculates discharge of a speed-controlled pump with a head-dependent capacity. When the pump is on, then the discharge of the pump depends on both the speed and the head. The discharges for different speeds and heads are defined in a table in a coefficientSet.

For the pump structures, the discharge is stored at the start of the next time step. It is therefore important to correctly configure the input and output time series sets in order to avoid missing time steps (gaps) in the output time series.
