Sources of error
- Comparisons should be made between watersheds; one watershed is not representative of the landscape.
- The area of riparian zones is
unequal due to the variability of stream segment length.
This could under-represent the range of bank elevation and modify
results.
- Overlapping and discontinuous riparian boundaries mean that some data is missing.
- Headwater streams in this landscape
are frequently less than 2m wide; most are less than 4m wide. The
elevation values found in the 2m buffer may include cells from outside
of the stream. This would probably increase topographic
variability estimates.
