Presentation Transcript

  1. Geomorphology GLG362/598 • Instructor: Kelin X. Whipple, kxw@asu.edu, ISTB4-777 (5-9508) • TA: Andrew Darling, aldarlin@asu.edu, ISTB4-603 • Office Hours TBA • Your Info (please jot down and hand in) • Year and Primary Interest (major/research focus) • Math/Physics/Geomorphology background • Software experience (ArcGIS, Excel, Matlab, SSH) • Own a laptop for in class use? • If yes, prefer local install Aps, or use MyApps online? • Reminder LAB: 1:15-3:15 Wed in H461

  2. Geomorphology GLG362/598 • Process-based instruction. • Textbook is complementary. I do not survey different landscapes (desert, coastal, permafrost, alpine, etc): Hillslopes, Channels (glaciers), +/- Floodplains • Teach how to think about all landscapes • How to read a landscape, how to proceed with a quantitative analysis • Project-based course • Hydrology; Hillslopes and Channel Heads; Alluvial Fans; Fluvial Processes; Landscape Evolution • Project Reports (no exams) • Every other lab -- 4 page (single, 12 point) plus figures, maps, cross-sections, calculations. • START EARLY, STAY ON SCHEDULE

  3. Geomorphology GLG362/598 • Field Trips • Depart EARLY – 7:30am; We Provide Vehicles; No Make Ups • #1 Sept 19-20 (Camping); Flagstaff Volcanic Field • #2 October 9,10, or 11 (Fri, Sat, or Sun); Verde River Hydraulics • Practical Skills • ArcGIS, Matlab/Excel • Airphoto Interpretation/ Mapping Surficial Units • Surveying (basics) • Stream gaging • DEM Analysis • A Few Grads: same exercises, different expectations

  4. Geomorphology GLG362/598 • Textbook • Geomorphology: The Mechanics and Chemistry of Landscapes, Anderson and Anderson, Cambridge University Press, 2010. • Class Website (not Blackboard) • http://whipple362.asu.edu/index.html • Motivations for Study of Surface Processes • First Wave Climate Science Completed: climate is changing, causes known • Second Wave Coming: what are consequences, how respond? • Landuse Change plausibly even more dramatic • Prediction: Need Quantitative Understanding of Processes / Record of Past Conditions/Responses • Earth System Response to Past Changes? • Record of Past Conditions (Tectonics, Climate) Preserved in Landscapes: Long Term Landscape Evolution

  5. Geomorphology GLG362/598 • Labs • First Lab Wednesday, Rm H461 • Topic is Landuse and Hydrology • Learn to Use ArcGIS • Lab 1 has 3 parts, Lab 1a deliverable due this Friday (nothing major – just need to keep pace with learning Arc) • Last Weekend’s Homework • Read Chapter 1 (pg 3-9) and Essay on “Landscapes and Geologic History” by Allen (3p), posted on class website (http://whipple362.asu.edu/index.html) • Class Discussion and/or Quiz : Questions?

  6. Taiwan Topography and Geology

  7. Orogenic WedgeTheory: Strong Climate-Tectonics Coupling Mechanics of Deformation: Theory for Control of Orogen Width; Strain Concentration Stolar et al, 2006 Penrose Volume

  8. DESERT JUNGLE Deflected Rivers ~12m Annual Rainfall

  9. TRMM Rainfall Map

  10. Beaumont et al., 2001 Nature Numerical Simulations: Strong Climate-Tectonics Coupling Willett, 1999 JGR

  11. Overview/Guidelines (Chapter 1) • Many interacting processes: wind, rain, runoff, ice, heat/cool, freeze/thaw, chemical attack – all modualted by life; all event-driven, variable • Our Approach: • Conservation (of mass [water, sediment, atoms], energy, momentum) • Transport Rules (flow of water ice, transport of sediment, etc) • Event Size, Frequency and Duration (storms, floods, climate variations, etc)
