swb_f: Soil water balance

Description

This function calculates the daily soil water balance and its components based on the rainfall, soil properties and vegetation properties.

Usage

swb_f(R, Rstar, Emax, Ew, Ks, b, Zr, n, sh, sw, sstar, nsteps, s0, gr)

Arguments

R

Daily rainfall, which should be a vector.

Rstar

The maximum amount which the canopy intercepts

Emax

Maximum evapotranspiration rate

Ew

Minimum evapotranspiration rate

Ks

Soil saturated hydraulic conductivity

b

The exponent of the water retention curve

Zr

Root depth

n

The soil porosity

sh

Soil moisture at hidroscopic point

sw

Soil moisture at wilting point

sstar

Soil moisture below field capacity point

nsteps

Number of steps/division for the numerical solution

s0

Initial soil moisture to start the simulation. If it is missing, s0 is signed equal to sh.

gr

Logical argument to show graphics of results. Default is FALSE

Value

soil water balance components
