Techniques for Stream Analysis.

Project Summary: Analyze existing stream data for appropriate classifications in regards to fish usage. Evaluate stream characteristics based on the Oregon Department of Forestry requirements for Western Oregon. Identify stream networks potentially misclassified and which may benefit from stream/fish survey.

Western Oregon - ODF Stream characteristics for Fish Usage:

Channel Steepness Less than 20%.

Drainage Basin greater then 90 acres.

Techniques for Stream Analysis. (cont.)

Data/Software Components:

Stream data source: 1:12,000 scale BLM Stream data, USGS 10 Meter DEMs for modeling.

SplitLines.mbx: Custom MapBasic Program used to Split Streams into uniform/manageable segments.

Vertical Mapper: Evaluate/Compute Stream Gradient.

StreamBuilder (from Avantra Geosystems): Used to Evaluate /Compute Drainage Basins.

Techniques for Stream Analysis. (cont.)Procedure Specifics: Stream Gradient.

Process stream network with SplitLines creating 1000 foot segments which break atStream intersections. Stream data must be clean, no duplicates or gaps.

Techniques for Stream Analysis. (cont.)Procedure Specifics:

Using Vertical Mapper, perform a “Line Inspection” on the 1000 foot segment data and Update stream segments with Min and Max elevations. (Note: Vertical Mapper Slope data is unreliable for stream analysis as slope computation may be influenced by grid cells on the sides of the stream segments.)

Procedure Specifics: Stream Gradient.


Once the Min/Max elevation values have been added to the 1000 foot segment data, stream gradient can be computed via the formula: (Elevation_Max - Elevation_Min) /ObjectLen(obj, "ft").

Use this to update a gradient column.



Finally a simple MapInfo Select statement can now be used to isolate the stream segments which have a gradient greater then 20%.



The StreamBuilder program can be used generate drainage basins for selected points. To determine specific drainage basin area for existing streams the SplitLines program was first used to generate a series of points at stream intersection locations.

Procedure Specifics: Drainage Basins < 90 Acres.


StreamBuilder creates drainage basins, stream networks and flow paths directly from a digital elevation models. USGS DEMs, MapInfo or Vertical Mapper Grids may be used as source model data. Prior to building a model, the DEM must be ‘Pit Fill’ processed to fix anomalies in the DEM and smooth any natural drainage regions.



Using a “Pit Filled” DEM StreamBuilder can then generate drainage basins, from selected points. Applying a minimum Basin Area of 90 Acres limits the Basin creation process to only basins greater then 90 acres. Attributes in the outlet Point table can be updated in the resulting Basins. Apply an ‘Outlet Detection Buffer’ if Outlets do not match model.



Once the Drainage Basins have been created the outlet points can be analyzed to determine which points DID NOT result in a Basin. These points indicate locations above which drain less then 90 acres.



In addition to creating Drainage Basins, StreamBuilder can also be used to generate Stream paths and Outlet points. Depending on the accuracy and detail of the DEM these paths and outlets may differ from your existing Stream Network.

Procedure Specifics: Additional Analysis Tools.


StreamBuilder can generate additional Analysis Grids such as a Flow Direction Grid where a value of 1 = East, to a value of 8 = South East.



An Upslope Area Grid is a grid where each cell contains a value based on the number of upslope cells which flow into it. This grid type will resemble the actual stream network generated by StreamBuilder.

StreamBuilder supports batch grid processing and resulting grids can be further analyzed using Vertical Mapper.



Stream modeling using StreamBuilder will only be as accurate as your source DEM data allows. Existing Stream data may be more precise. Apply “detection buffers” to adjust for differences in precision when asking questions. More detailed data such as LIDAR will increase precision of model.

Procedure Specifics: Closing Comments.
