The Stream Viewer allows for display and query of a DEM-derived () stream layer. The stream layer contains
many attributes related to fluvial geomorphology, aquatic habitat, erosion, riparian, and climate change.

Stream Viewer has slider bar functions that are used to filter the
stream layer data or to rank them by highest to lowest percentiles
(e.g., top 10% of salmon habitat, top 5% of erosion potential, and
top 15% of wildfire risk etc.).
A second slider bar allows you to identify critical interactions between two attributes – where they overlap – such as the locations where the top 10% of salmon habitats overlap with the top 10% of fire risk, etc.
Stream segments are 100m long. If you are zoomed out too far and/or have your query criteria set too low, there can be too many stream segments for the browser to display. The limit is set at 40,000.

First Slider
The first slider bar is used to display an attribute ranked by its absolute value or ranked by percentiles (the small button located above the slider).
For example: identify locations of the top 10% of salmon
habitat, top 5% of erosion potential, and top 15% of wildfire risk, etc..

Second Slider
The second slider bar is designed to work with the first slider to identify locations where two attributes that are ranked by their absolute or percentil e values overlap within a watershed.
For example, find locations where the top 10% of salmon habitats overlap with the top 10% of fire risk, etc.
