Detailed information of each scenario can be referred to the corresponding paragraph in Model setup and boundary conditions.
^aMetalimnetic withdrawal discharge in scenario V_max is the maximum discharge for each day of the year from 133 to 248, based on long-term measurements (years 1996–2015).
^bMetalimnetic withdrawal discharge in scenario T is the maximum discharge at each day from 182 to 205, based on long-term measurements
