Differences in SWAT+ toolbox and SWAT+ editor

[Madieke van Oosterhout]

Hi everyone,

I modeled a catchment in QSWAT+ and SWAT+ editor. From this model I exported flo_out data for several channels. 

I used the TxtInOut file from this model as input in the SWAT+ toolbox. When I ran the toolbox and extracted the results, I noticed that the daily Riverflow results from the toolbox differed significantly from the values extracted from the SWAT+ editor. For example, for a specific channel I get a value of 0,0221 for flo_out from the editor, while from the toolbox the Riverflow value for the same channel is 0,00148.

Do you have any idea what could cause this difference?

Thanx,

Madieke

it is caused by options on the Run Page of SPT. Make sure they match with what you have in SPE.

This might be useful to add: I used daily output values for both the Riverflow from the toolbox and the flo_out from the editor.

Hello Celray,

I have the same issue, and I'm using Rev. 61.0.1 in both cases.

What isthe code that use SPT on this topic:

- Max half-hour rainfall frac calc (I use code 1-"Use monthly maximum half hour rainfall value for all days in month")

And I use 0.2 (20%) for the Initial soil water storage expressed as a fraction of field capacity water content.

I think the rest of the options are by default.

Thanks.

I'm experiencing a similar situation where the outputs in the SPT are not the same as in the SPE for the simulated river flow and sediment data. I left all the basin codes (codes.bsn) the same for both cases and nothing changed. 

Were you able to resolve this? 

Thanks.

Swat+Toolbox doesn't have too many buttons to configure the multiple options which do appear in Swat+ Editor.

The more options you change there, the more differences there will be between the two, because you don't know which options the swat+ Toolbox is returning internally to their default values.

It's complicated.
