Assess students' ability to analyze and attribute regional streamflow trends to land‑use change versus climate variability using hydroclimatic datasets. Expected skills: selecting and preprocessing streamflow, precipitation, temperature, evapotranspiration, and land‑cover datasets; performing trend detection and statistical attribution (e.g., regression decomposition, sensitivity/perturbation experiments, hydrological modeling); designing comparative scenarios to isolate drivers; quantifying relative contributions and uncertainties; and interpreting implications for water resources and land management.
