SWAT Output Spatial Visualization

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 ArcSWAT, QSWAT and SWAT Viewer. You will see how SWAT viewer save your time and space.

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 happy to guide you through the process.

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 video, I will talk about the comparison functions in SWAT Viewer. Hope you found it’s helpful for your research.

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 the SWAT Viewer as long as you have the model input files saved in (scenarios -> scenario name-> txtinout) folder and the reach and subbasin shapefiles saved in (watershed -> shapes) folder.
