Background and why we're covering it

This class is focused on introducing fluvial geomorphology by reading riverscapes. Through moudles 1 through 9, you have been building up the pieces and skills to read any riverscape. In this module, we apply that at the riverscape reach scale. In other words, we identify the type or river style of the riverscape at the extent of a reach from both a bottom-up (geomorphic units as building blocks) and top down (catchment, landscape and valley-scale controls) perspective. We will explore the enormous diversity of riverscapes on this planet and how to take any riverscape anywhere and identify is defining and distinguishing attributes, and what you might call it.

Learning Outcomes

• LO 1. Confidently read any riverscape and be able to map its core characteristics.
• LO 3. Apply principles of geomorphic analysis to a diversity of riverscapes.
• LO 4. Recognize the primary controls on riverscape diversity, in which distinctive suites of physical and biotic processes (behavior) help shape the form and character of those landscapes.

Brierley & Fryirs (2005) River Styles Framework

The River Styles Framework is laid out in Part 2 of the Brierley and Fryirs (2005) book and is the conceptual basis for much of our book. For an overview lecture of the framework, see this Module in WATS 6860 Ecohydraulics.
