I was able to derive the catchments for each stream crossing. Now, I have two questions:
1. My question is how can i show flow direction? So that i can verify the upstream catchments generated are correct.
2. Is there a way eliminate the white gaps (between pour points and near the road alignment) between the catchments?
I have tried the vector field symbology in Flow direction raster but gives arrows not according to the streams.
I have tried the vector field symbology in the original dem raster and it gives better results but still alot of areas not in accordance with the stream generated.
I have attached a snapshot.
Thank you.
