Introduction to SWATtunR

SWATtunR

The goal of SWATtunR is to help with the SWAT+ model calibration and validation. These functions were developed and tested for the implementation of modeling tasks in the OPTAIN project, Nordbalt-Ecosafe and LIFE SIP Vanduo. Functions are initially developed by Christoph Schuerz, which added important capability on top of other R tools designed for the SWAT/SWAT+ models. Therefore, we highly recommend trying and using these tools:

• SWATbuildR¹ - R tool for building SWAT+ setups;
• SWATprepR - SWAT+ model input data preparation helper. The package is presented in the article Plunge, Szabó, et al. (2024);
• SWATfarmR - R tool for preparing management schedules for SWAT model;
• SWATdoctR - A collection of functions in R and routines for SWAT model calibration and model diagnostics. The package is presented in the article Plunge, Schürz, et al. (2024);
• SWATrunR - R tool for running SWAT models for different parameters and scenarios. Please install branch names remove_legacy. It could be done using line like this remotes::install_github("chrisschuerz/SWATrunR@remove_legacy")
• SWATmeasR² - R tool for implementing Natural/Small Water Retention Measures (NSWRMs) in the SWAT+ models and running scenarios.

Detailed information about packages, workflow steps, input data, SWAT+ parameters, model calibration, validation, etc., could be found in the SWAT+ modeling protocol Christoph et al. (2022).

Installation

You can install the development version of SWATtunR from GitHub.

# If the package 'remotes' is not installed run first:
install.packages("remotes")

# The installation of `SWATprepR`.
remotes::install_github("biopsichas/SWATtunR")

This work was carried out within the OPTAIN project (OPtimal strategies to retAIN and re-use water and nutrients in small agricultural catchments across different soil-climatic regions in Europe, cordis.europa.eu) which has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 862756 and the LIFE22-IPE-LT-LIFE-SIP-Vanduo project (Integrated water management in Lithuania, ref: LIFE22-IPE-LT-LIFE-SIPVanduo/ 101104645, cinea.ec.europa.eu), funded by the European Union LIFEprogram under the grant agreement No 101104645.
