Detailed Description
Surveyed channel heads matched in at least one of the predicted networks (dark blue) and surveyed heads missed in all networks (yellow). Field-derived networks are shown in light blue. Most channel heads missed by all methods were small offshoots or poorly defined channels (b, d) rather than major tributaries. Head a shows a poorly defined channel that was matched in at least one method and head c shows a matched head in the urban network originating just upstream of a culvert.
