As 2019 is ending, I want to share the work that occupied me for all of 2019 (and much of 2018). I had hoped that it would be completed by now, but there were roadblocks. On the flip side, I've met amazing people and learned cool skills working on this eartharxiv.org/5tg68
We reconstructed history of river discharge (also known as streamflow) of major rivers in Asia over the past eight centuries. We found that streamflow in the region is coherent, with floods and droughts often occurring at adjacent catchments and basins at the same time.
This result suggests that water management in the region be coordinated among adjacent basins.
We also found that the Pacific Ocean exerts its greatest influence on rivers in Southeast Asia. This means that if we monitor the state of the ocean, we can potentially improve water management here. This is related to a previous work I coauthored bit.ly/2Qs9HY8.
Things I learned while working on this:
- Making an R package
- Converting R code to C++ (22 times speed up)
- Parallel computing
- Linux
- Git and GitHub
- #rdatatable (shorter code that runs faster)
- GIS with R and QGIS
- Handling a rejection's emotions
... and many more
