Running the Tool

Since the intention is to get rid of things on the outside, switch the selection, and then simply press the "X" to delete those selected flowpaths, and everything should be a lot cleaner.

The next move is to select stream segments that have a Strahler stream order of at least 4 or greater.

1. Go down and press "Select by attribute."

2. Go down to "Strahler stream order, greater than or equal to 4," and press "Apply."

3. Take a quick look at all this and see that the main channel has been selected, as well as some of these larger branches.

4. In the stream type field, right-click and go to the field calculator, and assign these a StreamType Field of 1.

5. Press "OK."
