Each datafolder (1-5) contains the direct input data for Figures presented in the related 
publication (.Rdata format).

Input files for each simulation are provided (.csv format), and, if applicable (1-3), the 
Morris Trajectory (trajectory.csv) is given as well, to provide a summary of the provided 
input for multiple simulations. Note that these are relative to the input range chosen, 
which can be found in the related publication. 

For the numerical simulations, no raw model output is given. The water levels and drain 
discharge obtained from the numerical simulations is contained within the Rdata file, 
as ..wt and ..q dataframes (for 1-3). For (4), numerical results are saved in the Rdata 
file as ..Hnum and ..Qnum. Water levels are defined in meter with respect to soil 
surface, discharge is averaged over the area as m/d.

For the analytical simulations, all model output is contained within the Rdata file, such 
that not all data is used directly within the related publication. Note that the definitions 
of H, Hd etc. are slightly different, such that the head with respect to soil surface can be 
obtained as -D+H+Hd+Hx0. Similarly, total discharge can be obtained by Q+Qx0.

The source code folder contains the R source code used for modeling and processing data. 
The main input file for the numerical simulations is the DrainDiLeMaTool.R. Based on this 
input file, simulations can be performed without further interaction. In case one would 
like to re-simulate the data of the related publication, no new input datafile should be
created, hence the input.R script should be skipped when running the simulation. A copy of 
source code or software required for numerical modeling, such as SUTRA v2.2, Gmsh v3.02 
and MinGW, is included. The R version used (v3.5.3) is not included, but can be obtained 
via alternative sources. 

Processing algorithms of numerical results for the related publication, are given in 
'ProcessingAndAnalyticalFuns.R'. As we did not upload all numerical model results,
this script only functions when the numerical model is rerun with the correct input, such 
that all output is re-created. As the important output data is already available in the Rdata 
files these processing algorithms are mainly there for inspection.

The analytical model and processing algorithms are also given in 'ProcessingAndAnalyticalFuns.R. 
Note that source directories etc. should be set to their proper locations for correct 
functioning of the model.
