This tool checks specific attributes of each polyline in your river network . A topologically correct network would have:

oA unique ID for each polyline

oThe FROM and TO node fields would not have the same value for each polyline

A polyline which has the same node ID value for the FROM and TO node field could indicate a polyline looping or it was added to the network and user forgot to update these fields.

This tool generates an error log file called InvalidAttributes.txt
