QSWAT and MWSWAT is very similar in terms of interface design although they are programmed with different programming languages and in different GIS platform. In this video, these two SWAT tools are compared side-by-side to demonstrate the similarity. The guess is they are from the same development team. MWSWAT is developed first and QSWAT follows …
Tutorial #1: Open SWAT Project
Most of the SWAT users use ArcSWAT, QSWAT or MWSWAT to create their models. The SWAT projects created with these tools could be opened directly in SWAT viewer. If you uses other tools, you could also manually create a SWAT project and open in SWAT viewer. In this video, I will talk about how to …
SWAT Output Spatial Visualizaiton
There are many ways to see SWAT outputs. Spatial visualization shows the model results on a map. It will clearly show how the selected results are distributed across subbasins or reaches. It’s very useful to pinpoint the hotspots in the watershed. In this video, we will talk about how to do the spatial visualization with …
Add Modified SWAT Version to SWAT Viewer
The SWAT Viewer supports any modified SWAT versions so you can analyze the results and compare with other versions. This video shows you the steps to add your own modified version to the viewer. The viewer version code is not on Github for now. Please feel free to contact me. I will be more than …
Compare SWAT Versions in SWAT Viewer
A great thing about SWAT is that it's open source. The algorithms could be modified to best fit the study areas. For a modified version, it's important to demonstrate the effectiveness by comparing with the base version. The SWAT Viewer gives you all the tools to compare any two version in different angles. In this …
Manually Create SWAT Project to use SWAT Viewer
In some research, the SWAT models are created differently. Only the model input files and some of the shapefiles are available. In this case, you could manually create the swat project and use the SWAT viewer. The video will show you how to do that. For the subbasin and reach shapefile, make sure the subbasin …

Test your customized SWAT model with SWAT Output Viewer
In research, the SWAT source codes are usually modified to add new features or integrate new algorithms. To demonstrate the improvement, it's often required to compare with the official unchanged SWAT model. SWAT Output Viewer supports to quickly compare the SWAT outputs from two different SWAT versions. These two version could be from SWAT team …
