Dear Esri Members,
I was attempting to conduct research on a section of the Amazon River Basin and was attempting to find connecting rivers, however, I am only able to see these connecting rivers once I zoom in. Above is my computer image after I process my Digital Elevation Model->Perform the Fill Function-> and then run the Flow Accumulation Function.
Below is the image of DEM model.
I also wonder why the large Amazon river doesnt register as flow accumulation point in the model
