Subsurface stormflow concentration-discharge relationships reveal DOC and nitrate transport mechanisms across land uses in karst hillslopes

Key Points

• Concentration-discharge relationships unveil how dissolved organic carbon is transported through subsurface stormflow.
• DOC and nitrate transport varies significantly across different land uses in karst hillslopes.
• The findings use observational analysis to assess biogeochemical cycling in unique geological settings over time.
• Understanding these transport mechanisms could inform water quality management, especially in karst regions.
