Factors Controlling Contemporary Suspended Sediment Yield in the Caucasus Region

This repository contains the main processing steps to spatial variation of mean annual area-specific sediment yield (SSY, t km⁻² yr⁻¹). It is meant to accompany a journal article (Tsyplenkov et al., 2021). This study is part of the ongoing Russian Science Foundation project No. 19-17-00181: «Quantitative assessment of the slope sediment flux and its changes in the Holocene for the Caucasus mountain rivers.»

REPLICATION. HOW TO

1. Fork this repository or unzip the archive.
2. Using RStudio open "caucasus-sediment-yield2021.Rproj" file in the main project directory.
3. Run the R/00_prepare-r-session.R file.
4. Now you can run other files in R directory.

LOGIC OF THE PROCESS

The whole process is split into eight parts, which is reflected in the structure of R scripts. Every R file is independent and not related to others. For example, if you want to reproduce only correlation analysis , then run R/03_cor-analysis.R. The names of the scripts are quite indicative, and each script is reasonably commented.
