Calculates canopy snow interception

Description

Function canopysnowint calculates snow intercepted by the canopy in a single time step using the model of Hedstrom and Pomeroy (1998) Hydrological Processes, 12: 1611-1625.

Usage

canopysnowint(
  precd,
  uz,
  dtm,
  gsnowd,
  Lt,
  pai,
  plai,
  hgt,
  d = NA,
  zm = NA,
  phs = 375,
  Sh = 6.3,
  zu = 2
)

Arguments

uz	wind speed at height zu (m/s)
dtm	a raster of elevations
gsnowd	ground snow depth (cm)
Lt	snow load in previous time step (mm SWE)
pai	plant area index
plai	proportion of pai that is living vegetation (i.e. leaves)
hgt	canopy height (m)
d	optionally, zero plane displacement height of wind profile
zm	optionally, roughness length for momentum transfer
phs	optionally, fresh snow density (kg / m^3)
Sh	optionally, branch snow load coefficient (kg/m^2). 6.6 for pine and 5.9 kg for spruce.
zu	height above ground of wind speed measurement uz (m)
prec	daily precipitation (mm)

Value

Int snow water equivalent (mm) intercepted by canopy
