I've recently been working on a project that requires the use of Strahler stream order analysis. I've filled my sinks and removed peaks from my DEM. I've run the Flow Direction tool, Flow accumulation, Raster calculator (Flow Acc >= 100) and have run the stream order analysis using the Strahler method along with my calculated raster and flow direction rasters. What am I doing wrong in this? I see that I was able to obtain the stream orders, but I was told that I need to build a network. Please help!
