Module 8 - Exploring GUT to learn more about Geomorphic Units
- Due Apr 4 by 11pm
- Points 32
- Submitting a website url
In this assignment Links to an external site., you will explore GUT. Please see all the resources to complete this lab here Links to an external site., including what to turn in Links to an external site..
Don't get overwhelmed, this is really just browsing around the outputs of four GUT projects at two sites and answering some questions to make sure you understand what you're looking at.

2.2: Selection of Survey Years
Choose at least two survey years at this site to consider the temporal variability of morphology at this site. Which survey years are they and why did you choose them?

2.4: Tier 2 Form Assemblage
Do any of the Tier 2 Forms dominate the assemblage or is it fairly mixed? Is this true through time? Answer for both sites.

2.6: Arrangement of GUs
Zoom in to 2 to 5 x bankfull width portion of the reach and look at the arrangement of geomorphic units. Is it coherent? Does it make sense based on what you have learned so far?

2.7: Critical Evaluation of GUT Output
How well does GUT appear to be doing in each year at discriminating the in channel geomorphic units? Point out any weaknesses or concerns you might have.

2.7: Manual Mapping
Identify in one of your surveys for this reach a distinctive pool, bar and planar feature. For all three identify all five attributes from the fluvial taxonomy (i.e., Table 6), then use those to identify the tier 3 name from Table 7 or 8 (this may differ than what GUT output is because it is not as resolved) and explain which attribute(s) were key for discriminating that unit from other units.
