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 …

Model Structure of SWAT Project
SWAT projects created by ArcSWAT and QSWAT shares the same structure. In this video, I talked about the structure and how the SWAT Viewer use the information to run the model and show the model result on a map. If you are not using ArcSWAT or QSWAT to create your model, you still could use …
Input Conversion Error
Some SWAT users have experienced the input conversion error when running the SWAT model. The video below will show you what causes this error and how to fix it.
Exporting Map to PNG File
It has been requested to export the map to a file. Here it is:) Simply choose the Export Map menu from the map context menu (shown below). The map will be saved to a png file. Enjoy this function with version 0.1.0.1.
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 …

Quickly Check SWAT Model Performance with SWAT Output Viewer
During SWAT model calibration, the simulated flow, sediment, nitrogen and phosphorus results are frequently compared with observed values to evaluate the model performance. SWAT Output Viewer has the ability to quickly calculate several model performance indicators on-the-fly (as shown below) once the model simulation is done. To be able to compare with observed data, the …
