Detailed Description

PREVAH snow evaporation.

PREVAH evaporates snow at the (albedo-reduced) potential rate whenever snow is present (s_snoevap1.f90, default: et_snow = et_pot): S = PET * (1 - albedo)/0.8 where the albedo is the snowpack's own age-dependent snow albedo (PrevahSnowAlbedo of Snowpack::GetSnowAge, 0.4-0.85). Old (spring) snow has a low albedo, so it evaporates strongly - the dominant snow-evaporation sink. Requires PET forcing and a hydro-unit snowpack context; no evaporation when the snow container is empty.

Member Function Documentation

◆ AttachForcing()

void ProcessSublimationPrevah::AttachForcing ( Forcing * forcing )

overridevirtual

Attach forcing to the process.

Parameters

forcing forcing to attach.

Reimplemented from Process.

◆ GetRates()

const vecDouble & ProcessSublimationPrevah::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.

Implements Process.

◆ HasConstraintPriority()

bool ProcessSublimationPrevah::HasConstraintPriority ( ) const

inlinenodiscardoverridevirtual

Check if the process takes its demand from the water container with priority when the container cannot satisfy all outgoing rates. Non-priority processes then share the remaining water proportionally. Mirrors sequential (operator-split) reference models such as PREVAH, where snow evaporation is served at the full potential rate before melt.

Returns: true if the process has priority on the container constraints.

PREVAH serves snow evaporation sequentially BEFORE melt, so it gets the full potential rate even on days the pack drains completely; melt only takes what remains.

Reimplemented from Process.

◆ IsValid()

bool ProcessSublimationPrevah::IsValid ( ) const

nodiscardoverridevirtual

Check that everything is correctly defined.

Returns: true if everything is correctly defined.

Reimplemented from ProcessSublimation.

◆ RegisterProcessSettings()

void ProcessSublimationPrevah::RegisterProcessSettings ( SettingsModel * modelSettings )

static

Register the process parameters and forcing in the settings model.

Parameters

modelSettings The settings model to register the parameters in.
