Hello friends,

SWAT model generates huge amount of outputs, which could be analyzed in different ways (e.g. time series data, spatial distribution, model performance, and scenario comparison). You may have your own way to implement the analysis using Excel, R, Matlab or other tools. However, we couldn't find a tool that would has the ability to quickly view the analysis results right after the model simulation without generating extra files and installing other software packages. 

So we developed our own tool - SWAT Output Viewer. It's a small .NET application to
  • select SWAT components on map, view and modify key SWAT files
  • run simulation using different model engines
  • display results using thematic map and time series graph
  • quickly calculate model performance (e.g. Nash-Sutcliffe Efficiency and R2)
  • compare any outputs from different model engine or scenario
This tool is a very small stand-alone application. It doesn't required other software packages. And no extra files are generated. All analysis are done on-the-fly. 

A screenshot is shown below with thematic map in the middle and time series graph on the bottom. The installation file and user manual is available at my blog https://zhiqiangyu.wordpress.com/2016/04/09/an-interface-to-quickly-view-swat-ouputs/. 

Hope you find this tool is helpful for your research. 

Regards
Michael

This tool is fantastic, thanks! The results look great and it is very easy to run. 

Question: I am using SWAT-MODFLOW, and I would like to load the results of a SWAT-MODFLOW run in SWAT viewer. Is there a way to do this? I only see the option to launch a new SWAT (uncoupled) run in SWAT viewer. 

I don't think so, but I thought I would ask! 

Thanks,

Great tool, thank you.
Is there a way to load NOT an ArcSWAT project, but just a SWAT project?

Just wants to add that the SWAT Output Viewer has been list on the SWAT website and a Youtube channel is also online now. Please feel free to subscribe and give comments.  Cheers.

Hi Michael,

Can Swat Output Viewer be used with QSWAT+ results?

Thanks.
