Simple interface to the hydromad "leaky bucket" soil moisture model.
simpleWB( PPT, PET, D, thickness, sat, fc, pwp, S_0 = 0.5, a.ss = 0.05, M = 0, etmult = 1 )
precipitation series (mm)
potential ET series (mm)
soil thickness (cm)
volumetric water content at saturation (satiated water content)
volumetric water content at field capacity (typically 1/3 bar suction)
volumetric water content at permanent wilting point (typically 15 bar suction)
initial soil moisture as a fraction of total water storage (mm)
recession coefficients for subsurface flow from saturated zone, should be > 0
fraction of area covered by deep-rooted vegetation
multiplier for PET
Adjustments for coarse fragments should be made by reducing
