This HydroShare repository contains the complete dataset, modeling code, and regional application results for the study "Upscaling sediment source prediction for watershed management" (Percich et al., 2026). The collection provides a global meta-analysis synthesis and a Multivariate Random Forest (MVRF) machine learning framework designed to predict the proportional contributions of four primary catchment sediment sources: Subsurface, Cultivated, Non-Cultivated, and Infrastructure.
Repository Structure:
1. Data Preparation: Delineates watersheds used in the model and analyzes meta-analysis data.
2. Model Development: Trains multivariate random forest (MVRF) model and conducts Shapley feature importance.
3. Model Application: Evaluates model applicability in new basins and applies the model.
4. Supplemental Excel Files: Tabulated source fingerprinting metadata including study sampling techniques, mixture classification, tracer types, reported catchment areas, and DOI bibliographic reference tables.
