Short summary
We provide a first determination of k in human-impacted subtropical streams and small rivers. High and highly variable k values reflect different controls on water turbulence. New models of k are developed using water depth and flow velocity. We show that previous estimates of riverine CO2 evasion from subtropical streams and small rivers are conservative and highlight the importance of incorporating scale-appropriate k measurements into extensive pCO2 investigations for accurate C budgets.
