dischargeinterfaces

This module defines interfaces for calculating discharge based on flow formulas or rating curves.

Module dischargeinterfaces implements the following members:

• DischargeModel_V1 Simple interface for calculating discharge in m³/s based on the current water depth.

• DischargeModel_V2 Simple interface for calculating discharge in mm/T based on the current water depth.

---

class hydpy.interfaces.dischargeinterfaces.DischargeModel_V1

Bases: SubmodelInterface

Simple interface for calculating discharge in m³/s based on the current water depth.

typeid: ClassVar[Literal[1]] = 1

Type identifier for DischargeModel_V1 submodels.

prepare_channeldepth(channeldepth: float) → None

Set the channel depth in m.

prepare_tolerance(tolerance: float) → None

Set the water depth-related smoothing parameter in m.

calculate_discharge(waterdepth: float) → float

Calculate the discharge based on the water depth given in m and return it in m³/s.

class hydpy.interfaces.dischargeinterfaces.DischargeModel_V2

Bases: SubmodelInterface

typeid: ClassVar[Literal[2]] = 2

Type identifier for DischargeModel_V2 submodels.

prepare_channeldepth(channeldepth: float) → None

Set the channel depth in m.

prepare_tolerance(tolerance: float) → None

Set the water depth-related smoothing parameter in m.

calculate_discharge(waterdepth: float) → float
