i hope someone can answer me my simple question. I have two sets of data
a river network --> line feature
discharge points along those rivers --> Point Data
The discharge points represent wastewater treatment plants. I try to find those treatment plants which don't have a inflow of another river, for a minimum of 2 km downstream. This means the river from this point on does not intersect with another river for at least 2km.
How can i find those plants? Are there any tools for this? What about the Arc Hydro tools?
