FluvialTracer: A Comprehensive Package for Sediment Source Unmixing

Source apportionment toolkit for fluvial catchments and river sediment provenance. It estimates how much each source contributes to a sediment mixture, using frequentist, Bayesian, and machine-learning models on the same dataset. The software includes tools to check which tracer is causing an unrealistic result, plus built-in validation against artificial mixtures with known, true source proportions.
