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 at
Stream intersections. Stream data must be clean, no duplicates or gaps.
Techniques for Stream Analysis. (cont.)
Procedure Specifics: Stream Gradient.
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.)
Techniques for Stream Analysis. (cont.)
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.
Techniques for Stream Analysis. (cont.)
Procedure Specifics: Stream Gradient.
Finally a simple
MapInfo Select
statement can now
be used to isolate
the stream
segments which
have a gradient
greater then 20%.
Techniques for Stream Analysis. (cont.)
Procedure Specifics: Drainage Basins < 90 Acres.
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.
Techniques for Stream Analysis. (cont.)
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.
Techniques for Stream Analysis. (cont.)
Procedure Specifics: Drainage Basins < 90 Acres.
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.
Techniques for Stream Analysis. (cont.)
Procedure Specifics: Drainage Basins < 90 Acres.
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.
Techniques for Stream Analysis. (cont.)
Procedure Specifics: Additional Analysis Tools.
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.
Techniques for Stream Analysis. (cont.)
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.
Techniques for Stream Analysis. (cont.)
Procedure Specifics: Additional Analysis Tools.
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.
Techniques for Stream Analysis. (cont.)
Procedure Specifics: Closing Comments.
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.
