Evidence for Active Tectonics in local watersheds-Fluvial geomorph
Initial Publication Date: July 10, 2008
Summary
In this lab, student analyze imagery from fieldtrip sites to identify fluvial geomorphic and tectonic processes.

Context
Audience
Upper division dedicated geomorphology course
Skills and concepts that students must have mastered
know how to
-interpret images to identify faults
-make map measurements to calculate mountain sinuosity and stream gradients and lengths
-identify watershed boundaries from maps

How the activity is situated in the course
Stand alone exercise about mid-way through course
Goals
Content/concepts goals for this activity
Interpretation of imagery taken from field trip sites visited the week previously by students
Higher order thinking skills goals for this activity
Identification through field observation and map/image in lab measurements of processes that create landforms occuring over long time-scales
Other skills goals for this activity
Students generally work in groups and bounce hypotheses off one another. Group discussions foster rejection of ill-formed ideas and focus and hone better hypotheses about how land-forming processes are working locally.
Description of the activity/assignment
Students have read pertinent chapters in text, read synergistic journal papers, and done homework assignments to prepare for a fieldtrip to areas featured in lab. Having visited and viewed areas of interest they are asked to analyze pertinent images for landform quantitative parameters.
