Abstract
The attached files include all the data and code applied in the paper
Notion: hr in the soil hydraulic model should be -1.0e4 cm, which was written mistakenly as -1.0e3 cm in Wang et al. (2022)
Wang, Y., Zhou, J., Ma, R., Zhu, G., & Zhang, Y. (2022). Development of a New Pedotransfer Function Addressing Limitations in Soil Hydraulic Models and Observations.

The developed pedotranfer function codes for predicting soil hydraulic properties of the FXW and FXW-M1 model from soil texture information are provided in the form of Matlab, Python and R. Please refer to
PTFs_FXW_Matlab.zip and PTF_FXW&SL_Python&R.zip for detail.
The code for improving the predictions of SHPs with the existing PTFs/ or only measurements in high water potential range is provided in code_for_FXW_SHP_EXT.zip.
The readme.txt was included in each zip file.

1. PTF_FXWSL_PythonR.rar file includes the PTFs developed for predicting the parameters of the FXW-M1 model and the SL of eqaution (12)
in Wang et al. (2022) WRR paper
-to run the model
(1) just provide the soil texture information ((Sand*100%, Silt*100%, Clay*100%,/BD*g/cm^3)) in the 'soil_texture. xlsx' file
(2) run FXpredict.py/FXpredict.R to get the parameters of the FXW-M1 model
run SLpredict.py /SLpredict.R to obtain the value of SL
(3) The output is shown in 'FXWJD_Parameter.xlsx'/'slope.xlsx'.
2. PTFs_FXW_Matlab.rar file includes the PTFs developed for predicting the parameters of the FXW model
-to run the model
(1) Provide the soil texture information (sand,silt,clay,bd (model H3)/sand,silt,clay (model H2)) in "Tex.txt" file
(2) run FXW_PTF.m file
you can change the index 'i_FXW;i_EXT,i_H' to chose different PTF in the matfile
(3) The ouptput is in "Par_PTF.mat"
3. code_for_FXW_SHP_EXT.rar file includes the method for extending exisiting PTFs to dry range
-to run the model
(1) Preparing the input: -- Providing the soil texture inforamtion in "Tex.txt" file
--if the input is the parameters of the VGM model, providing them in the "Par_VG.txt" file;
--if the mearsurments of water retetntion and hydarulic conductivity are availiable, providing
the meansurements in "SWRC.txt" and "HCC.txt" files
(2) run FXW_SHP_EXT.m file
you can change the index "i_PTF" in the matfile
(3) Output is in Par_FXW.mat [alpha,n,m,ths,Ks,l]
