@bwj202, I know this thread is from a while ago but I have been having a similar issue recently where using both reach mode and catchment mode results in an outlet discharge that is an order of magnitude greater than it should be. How did you solve your issue (2) above?

Hi @bwj202, if you turn off rainfall data (rainfall_data_on: no
) and run in hydro_only mode, with reach_mode switched on, that is essentially a "reach only mode". In practice, the routing algorithms for reach mode and catchment mode are the same, it just depends on whether you are adding water inputs from rainfall (over the whole catchment) or whether you are specifying a specific point to add water (reach_mode_on).
Turning off TOPMODEL entirely, I haven't considered that before really, good question. TOPMODEL runs fairly independently in the model, and the output catchment.dat file produces a TOPMODEL estimated discharge in a column next to the LISFLOOD shallow-water routing equations discharge. You could potentially remove it from the code entirely...I'd have to think about whether it is used in any of the other routines though...
