Geomorphology GLG362/598 Instructor: Kelin X. Whipple, kxw@asu.edu, ISTB4-777 (5-9508) TA: Emily Zawacki, eezawack@asu.edu, ISTB4-603 Office Hours – just make an appointment 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? Rec: bring to lab Reminder LAB: 12:55-2:55 Wed in PSH461

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

Geomorphology GLG362/598 Field Trips Practical Skills Depart EARLY – 7:30am; We Provide Vehicles; No Make Ups #1 Sept 8-9 (Camping); Flagstaff Volcanic Field #2 Sept 30 (Sat); Verde River Hydraulics Practical Skills ArcGIS, Matlab/Excel, Jupyter Notebooks Airphoto Interpretation/ Mapping Surficial Units Surveying (basics) Stream gaging DEM Analysis 30% Grads: same exercises, different expectations

Geomorphology GLG362/598 Textbook Class Website (not Blackboard) 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? Seismic Hazard Assessment Record of Past Conditions (Tectonics, Climate) Preserved in Landscapes: Long Term Landscape Evolution

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) The 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: Start with Written Questions, then please hand in your questions

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)
