1. Rivers and Beaches (ESS/Ocean 230) Dave Montgomery Chuck Nittrouer 341 Johnson Hall / 685-2560 111 Marine Sciences Building / 543-5099 bigdirt@uw.edubigdirt@uw.edu nittroue@ocean.washington.edunittroue@ocean.washington.edu Emily Eidam 110 MSB / 543-8544 efe@uw.edu

2. Geomorphology Professor, Dept of Earth & Space Sciences Ph.D., University of California, Berkeley Dave Montgomery studies the evolution of topography and the influence of geomorphological processes on ecological systems and human societies. His work includes studies of the evolution and near-extirpation of salmon, fluvial and hillslope processes in mountain drainage basins, the evolution of mountain ranges (Cascades, Andes, and Himalaya), and the analysis of digital topography of Earth and Mars.

3. Marine Geology and Geophysics Professor, School of Oceanography and Dept of Earth & Space Sciences Ph.D., University of Washington Chuck's research interests include the modern and ancient formation of sedimentary strata in continental- margin environments. Ongoing research includes coastal areas near the Amazon and Mekong Rivers, tidewater glaciers in Patagonia, and the impacts of dam removal from the Elwha River. Other recent studies have been completed in New Guinea-Australia, the Mediterranean, and off Antarctic and Alaskan glaciers.

4. Topics to be covered Earth Surface Processes Mountains  Rivers  Beaches  Ocean Holistic view, including: 1) Solid Earth 2) Atmosphere Linkages of all these will be an emphasis of the course.

6. In order for there to be mountains, rocks must be uplifted above sea level. If uplift continued unopposed there would be no limit to how high mountain ranges can get.

7. Erosion counter-balances rock uplift

8. Mountain streams receive material from hillslopes and transport it to rivers

9. Rivers transport material to the coast

10. Nearshore processes redistribute sediment along beaches and coastlines

11. Types of beaches reflect differences in sediment sources and transport

12. Earth Surface = where we live Recent Dramatic examples: Centralia rainfall  landslides  flooding New Orleans/Galveston hurricane  wind  storm surge Indonesia / Japan earthquake  submarine landslide  tsunami emphasis on understanding fundamental processes, but shock and awe will come with some examples

13. Rivers and beaches are part of sediment transfer systems. What forms them? What are the processes that maintain them? Why are there different types of rivers and beaches? What controls their distribution across Earth’s surface?

14. We’ll use 1 equation in this class I - O =  S Input minus output equals change in storage. Also known as conservation of mass  means change in something 

39. Bring clothes for bad weather (rain, cold, wind) -- even if it doesn’t seem like you’ll need them! Field Trip Tips

40. Please Note The course puts a high premium on the learning that comes from field observations. Participation in field trips is required to get credit for field trips. There are no make-up trips or alternate work that can be substituted for the trips.

41. If you miss one, your options are: For 3-credit registrants: 1) If you miss Field Trip A, you can go on Field Trip C; 2) you can take a zero for the field trip; 3) you can drop the course. For 5-credit registrants: 1) If you miss a trip, you can drop to 3 credits; 2) you can take a zero in the missed trip; 3) you can drop the course.

42. Field Trip A will be held twice, both on Wednesdays (8 and 15 Oct). Field Trip B will be held on a Wednesday (22 Oct). Field Trip C will be held on a Saturday & Sunday (25 & 26 Oct). If you need a note explaining your absence from other classes, please contact Chuck or Dave at least a week before the trip. Contact Emily (efe@uw.edu) to sign-up for Field Trip A on either 8 or 15 Oct.efe@uw.edu Reservations will be limited for each day, and will be accepted on a first-come basis.

46. Source to Sink A different way of seeing landscapes…

47. The Big Picture = The Rock Cycle

48. Material eroded from mountains enters streams and rivers and is delivered to coastal environments, from where it is moved to deeper sedimentary basins that get shoved back into mountains through processes of rock uplift. The Rock Cycle

50. Erosion in the Rock Cycle

51. What we see as rivers and beaches are rest stops for sediment moving through the eroding half of the rock cycle.

52. Framework for this Class Rock uplift  Mountains Mountains  Mountain Streams Mountain Streams  Rivers Rivers  Estuaries Estuaries  Beaches Beaches  Off-shore depositional basins Off-shore depositional basins  Rock uplift.
