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. Take1.pngAbove 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
