Description:
This repository containes model scripts and documentation 
that can be used to create a runoff pattern including the effects of
tillage-induced oriented roughness. The TCRP model has as main aim to adjust 
flow patterns based on topography for tillage induced roughness. The resulting 
output of TCRP are flow pattern raster maps, which can be further used as input 
for hydrological modelling of surface runoff processes. The scripts are written 
in the PCRaster GIS language, and depend on PCRaster (v4.4.0) to work properly. 
The files included are described below.

Files and Folders:
In Documentation.zip the following files can be found:

Introduction.pdf:  with an introduction to the 
		  models, also available as Word-file (Ms-office 97).
Manual.pdf: A PDF-file with explanation on how the model 
	    scripts should be applied, also available as Word-file (Ms-office 97).
Correction_figs.ppt: A PowerPoint-file (Ms-office 97) with figures described in 
                     the appendix in the manual.


Models.zip the model scripts, i.e. files with extension 'mod'. This are text files. 
For explanation on the different model scripts see the manual.

## Software
============================================================================================================

SoftwareRequired: 

To use the PCRaster scripts the PCRaster (v4.4.0) GIS software is needed. 
https://pcraster.geo.uu.nl/

A detailed guide to install the PCRaster software can be found at: 
https://pcraster.geo.uu.nl/pcraster/4.4.0/documentation/pcraster_project/install.html


OtherSoftwareRequirements: 

To run the TCRP scripts the commands as described in the manual can be excuted from the command line. 
A graphical user interface to work with PCRaster is NutShell, this is available at: https://github.com/vjetten/NutShell/releases/tag/NutShell
