cstG.DNmodel(wg, wpm, hp, Gamma, Srn, Srw, phi, rho, Cs, hL,
  NLAY = length(hL))

cnvG.DNmodel(wg, wpm, hp, Gamma0, Srn, Srw, phi, rho, Cs, hL,
  NLAY = length(hL))

Arguments

wg

numeric [1] or [NLAY]; ganglia width

wpm

numeric [1] or [NLAY]; maximum pool width (may be Inf in the lowest layer, in which case no DNAPL is allowed to escape)

hp

numeric [1] or [NLAY]; pool height, or total height of pools in a layer

Gamma, Gamma0

numeric [1] or [NLAY]; empirical source depletion parameter, positive; small values (<1) imply a more persistent source term
for cstG.DNmodel, \Gamma is constant throughout the model, but for cnvG.DNmodel, \Gamma converges linearly from Gamma0 (at peak mass) to 1 as the NAPL mass depletes.

Srn, Srw

numeric [1]; residual saturations of NAPL and water

phi

numeric [1] or [NLAY]; bulk porosity of each layer

rho

numeric [1]; solvent density (ensure consistent units, probably kg/m^3)

Cs

numeric [1]; solvent solubility in water (ensure consistent units, probably kg/m^3 which is the same as g/l)

hL

numeric [1] or [NLAY]; the height of each layer; note that higher layers will contain more NAPL mass

NLAY

integer [1]; number of layers in the DNAPL model

Value

a DNAPLmodel S4 object
