Simple interface to the hydromad "leaky bucket" soil moisture model

Description

Simple interface to the hydromad "leaky bucket" soil moisture model.

Usage

simpleWB(
  PPT,
  PET,
  D,
  thickness,
  sat,
  fc,
  pwp,
  S_0 = 0.5,
  a.ss = 0.05,
  M = 0,
  etmult = 1
)

Arguments

PPT	precipitation series (mm)
PET	potential ET series (mm)
D	dates
thickness	soil thickness (cm)
sat	volumetric water content at saturation (satiated water content)
fc	volumetric water content at field capacity (typically 1/3 bar suction)
pwp	volumetric water content at permanent wilting point (typically 15 bar suction)
S_0	initial soil moisture as a fraction of total water storage (mm)
a.ss	recession coefficients for subsurface flow from saturated zone, should be > 0
M	fraction of area covered by deep-rooted vegetation
etmult	multiplier for PET

Details

Adjustments for coarse fragments should be made by reducing thickness.

Value

a data.frame
