Function Documentation

fit_bc()

fit_bc	(		pF,
			theta,
			count = 1,
			verbose = False )

Fits the vanGenuchten Mualem retention curve into measured soilphysics values
:param pF: A sequence of pF values
:param theta: A sequence of the volumetric water content in l water/l soil at the respective pF value
:param count: Times to repeat the minimization to avoid local minima
:param verbose: If True: Print the values in between
:return: (Retentioncurve, RMSE)

fit_vgm()

fit_vgm	(		pF,
			theta,
			fit_m = False,
			fit_theta_r = False,
			count = 1,
			verbose = False )

Fits the vanGenuchten Mualem retention curve into measured soilphysics values
:param pF: A sequence of pF values
:param theta: A sequence of the volumetric water content in l water/l soil at the respective pF value
:param fit_m: If True, the retention curve is fitted with a variable m (deprecated by vanGenuchten)
:param fit_theta_r:  If True, the retention curve is fitted using a theta_r (kind of deprecated by vanGenuchten)
:param count: Times to repeat the minimization to avoid local minima
:param verbose: If True: Print the values in between
:return: (Retentioncurve, RMSE)
