DEM has over 159 million cell

[Daffodil gul]

Hello there,

I am using QSWAT+ and I am at a very early stage. When I add my DEM layer, I receive this message: "This DEM has over 159 million cells and could take some time to process! Be patient!"

However, when I try to burn my streams, it reaches the stage below and then nothing happens after that. I thought it might take some time, so I gave it 24 hours, but it seems that QGIS is not using much CPU or memory according to the task manager. When I click on it, it goes to "Not Responding."


What would be the solution here?

Try reducing the DEM raster to a more manageable size (you can mask the DEM layer using a rough guesstimation of the watershed extent).
