Detailed Description

Open-water (potential) evaporation with the PREVAH snow-albedo reduction.

As 'et:open_water' (evaporates at the potential rate, capped at the available content), but the potential rate carries PREVAH's (1 - albedo)/0.8 term, with the albedo interpolated between the snow-free and snow albedo by the hydro unit's snow-covered fraction (see HydroUnit::GetSnowCoverFraction): Ea = min(et_factor * PET * (1 - albedo)/0.8, content / dt)

Used for the canopy evaporation of an interception store in PREVAH setups (the interception ET draws from the albedo-reduced PET, scaled by the vegetation-cover fraction veg_cov via the et_factor parameter, which can be made monthly). With no snow (and the defaults albedo_land = 0.2, et_factor = 1) the rate matches 'et:open_water' exactly. Requires a hydro-unit context (hydro-unit bricks only).

Member Function Documentation

◆ GetRates()

const vecDouble & ProcessETOpenWaterPrevah::GetRates ( )

overrideprotectedvirtual

Get the rates of the process.

Implementations must store their result via StoreRates() (or directly in the _changeRates buffer) and return the reference, to avoid allocating on the hot path.

Returns: reference to the reusable buffer holding the rates.

Reimplemented from ProcessETOpenWater.

Reimplemented in ProcessETWetSurfacePrevah.

◆ IsValid()

bool ProcessETOpenWaterPrevah::IsValid ( ) const

nodiscardoverridevirtual

Check that everything is correctly defined.

Returns: true if everything is correctly defined.

Reimplemented from ProcessETOpenWater.

Reimplemented in ProcessETWetSurfacePrevah.

◆ RegisterProcessSettings()

void ProcessETOpenWaterPrevah::RegisterProcessSettings ( SettingsModel * modelSettings )

static

Register the process parameters and forcing in the settings model.

Parameters

modelSettings The settings model to register the parameters in.

◆ SetParameters()

void ProcessETOpenWaterPrevah::SetParameters ( const ProcessSettings & processSettings )

overridevirtual

Assign the parameters to the process.

Parameters

processSettings settings of the process containing the parameters.

Reimplemented from Process.
