Fluvial Geomorphology

Fluvial Geomorphic Processes

Module 6: Fluvial Geomorphic Processes - Sediment movement and deposition in river systems

See Corresponding Assignment

Background

Why we’re covering it

This chapter covers some of the most fundamental concepts surrounding fluvial geomorphic processes. We will take our time working through it slowly.

Learning Outcomes

  1. Differentiate influence of extenrnal controls (e.g. climate and catchment) vs. local controls on form and process.
  2. 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.
  3. Gain an appreciation of how geomorphic processes of erosion, deposition transport and storage of sediment shape topography and create, maintain, sculpt and destroy distincitive landforms.

Resources

We cover Module 6 and Chapter 6 by breaking it up into a bunch of smaller pieces. Please read the corresponding part of the chapter, watch one sequence of lectures, post questions on the discussion board. Then, move on to the next one.

Sediment Calibre & Loads - Slides & Handouts (Part 1)

This corresponds to the first two sections of the chapter (pages 81-84). There is way more in this section than you might first expect.

Part 1 - Lecture Playlist


36 minutes

Hjulström Diagram & Sediment Entrainment - Slides & Handouts (Part 2)

This corresponds to the next two sections of the chapter (pages 84-87).

Part 2 - Lecture Playlist


45 minutes

Sediment Transport and Material Properties that Affect Sediment Movement - Slides & Handouts (Part 3)

This corresponds to next two sections of the chapter (pages 88-102).

Part 3 - Lecture Playlist


30 minutes
Note § Material Properties that Affect Sediment Movement was covered in class lecture.

Sediment Deposition and Interpreting Sediment Sequences as a Tool to Read Riverscapes (Part 4)

This corresponds to next two sections of the chapter (pages 102-114).

Part 4 - Lecture Playlist


17 minutes
Note § Interpreting Sediment Sequences as a Tool to Read Riverscapes was covered in class lecture.
