| General Comments: | This study features regional-scale modelling of soil heterotrophic respiration (RH), which is the first RH modelling that has been performed using SWAT. This was accomplished by inserting a a newly developed, mechanistic, hydro-biogeochemical model into SWAT that simulates RH Meteorological variables, dissolved oxygen and redox potential dominantly control RH. |
