Constructor & Destructor Documentation

SnowDrift::SnowDrift ( const SnowpackConfig & i_cfg )

void SnowDrift::compSnowDrift	(	const CurrentMeteo &	Mdata,
		SnowStation &	Xdata,
		SurfaceFluxes &	Sdata,
		double &	forced_massErode
	)		const

Erodes Elements from the top and computes the associated mass flux Even so the code is quite obscure, it should cover all of the following cases:

Externally provided eroded mass (for example, by Alpine3D); see parameter forced_massErode
SNOW_REDISTRIBUTION is true: using vw_drift to erode the snow surface on the windward virtual slope
SNOW_EROSION is true: using vw to erode the snow surface at the main station (flat field or slope).
SNOW_EROSION is true and SNOW_REDISTRIBUTION is false: using vw_drift (if available and larger than vw) to do virtual erosion either on flat field (#slopes == 1) or on windward slope (#slopes > 1).
Note
However, erosion will also be controlled by mH and thus a measured snow depth (HS1) is required

If either measured snow depth is missing or the conditions for a real erosion are not fulfilled, the possibility of a virtual erosion will be considered using the ErosionLevel marker (virtual erodible layer).

Parameters

Mdata

Xdata

Sdata

forced_massErode if greater than 0, force the eroded mass to the given value (instead of computing it)

const double SnowDrift::schmidt_drift_fudge = 1.0

static

Deviation from geometrical factors defined by Schmidt.
