A subset of the NHDWaterbody layer filtered using specified NHD FCodes.
A subset of the NHDArea layer filtered using specified NHD FCodes.
The NHDArea and NHDWaterbody layers combined.
The NHDFlowlines layer with an attribute ‘bankfull_m’ added that is used to buffer the network. This layer is the network without the segments that fall within NHDWaterbody or NHDArea features.
Polygons derived by buffering the bankfull_network feature using the ‘bankfull_m’ attribute. This value is calculated using region equations for bankfull width.
The bankfull polygons with areas that overlap the NHDArea layer removed.
A polygon feature class representing the bankfull channel for the input network. The filtered NHDArea and NHDWaterbody features are combined with the buffered NHDFlowline features to create a single feature class.
