The "River and Stream" data category contains attributes displayed in the river network, at the scale of approximately 100 m (328 feet) reaches. The data include channel attributes such as drainage area, gradient, channel width, depth, mean annual flow, stream order and floodplain width.

 

The River and Stream data also include terrestrial characteristics covering erosion potential, road attributes, upland vegetation, riparan conditions, wildfire and climate change. These types of terrestrial attributes are summarized within a stream reach's local contributing drainage area located on either side of the stream (see Figure). In other words, you  get a stream-eye or a fish-eye view of attributes such as landslide potential, road erosion potential, vegetation age, wildfire risk and climate change, among others.

 

(Left panel) (A) NetMap's synthetic river network using approximately 100 m reaches; black dots denote tributary confluences. (B) Shows the local contributing drainage area on both sides of the stream channel to the ridge, called "drainage wings". (C) How drainage wings look acros a small watershed. (D) An illustration of a drainage wing showing how different terrestrial attributes such as erosion potential, road length (or density), forest ages etc. are summarized at that scale (approximately 0.1 km2) and reported to channel networks. (F) This allows hillside or terrestrial attributes to be related, spatially, to in-stream attributes such as aquatic habitats. (Right panel) On the left is the predicted shallow landslide potential (hillslope attribute). On the right is the stream-eye or fish-eye view of landslide potential, shown in the channel network.

 

Another example. On the lower right corner, note that channel attribute of post fire surface erosion is routed downstream, revealing tributary scale patterns.
