Djankuat river (Caucasus Mountains) sediment source fingerprinting

This repository centralizes the main processing steps to explore sediment dynamics after exceptional erosion event. 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.»

For a deep introduction to the study, please refer to:

Elucidating suspended sediment dynamics in a glacierized catchment after an exceptional erosion event: The Djankuat catchment, Caucasus Mountains, Russia.

REPLICATION. HOW TO

1. Fork this repository or unzip the archive.
2. Using RStudio open "djankuat-fingerptinting.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 four 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 fingerprinting results, then run R/04_fingerprinting.R. The names of the scripts are quite indicative, and each script is reasonably commented.
