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
