Dataset and algorithms for identifying stagnation zones and reverse flow caused by river-aquifer interaction

This dataset is part of the Supplementary Material of the research: Identifying stagnation zones and reverse flow caused by river-aquifer interaction: An approach based on polynomial chaos expansions. The code infrastructure, the programming scripts, the simulation results, and the dataset files are stored in this online repository. The results of the research and the simulation can be reproduced by following the instructions in the "readme.md" file.
