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.

Sarah studies rivers and how they change over time, specifically looking at controls on river incision rates and the formation of bedrock river terraces. Her work focuses on Pacific Northwest Rivers such as the Willapa, Satsop, Nehalem, and Teanaway Rivers.

Jonathan studies how landscapes change through time, from the glaciers and rivers that sculpt mountain ranges to the individual rocks that line the bed of rivers. Locally his work focuses on rivers draining Mount Rainier and the deglaciating Cascade Range.

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 could rise.

Erosion counter-balances rock uplift

Mountain streams receive material from hillslopes and transport it to
rivers

Rivers transport material to the coast

Nearshore processes redistribute sediment along beaches and coastlines

Earth Surface = where we live
Recent Dramatic examples:
Centraliarainfall landslides flooding
New Orleans/Galvestonhurricane wind storm surge
Indonesia / Japanearthquake submarine landslide tsunami
emphasis on understanding fundamental processes, but shock and awe will come with some examples
(the flip side = these same environments produce most natural resources)

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 the Earth surface?

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

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.
![Page 35: Rivers and Beaches (ESS/Ocean 230) Chuck Nittrouer Sarah Schanz 111 Marine Sciences Building / 543-5099 432 Johnson Hall / 206-616-0799 nittroue@uw.edu](https://reader035.vdocuments.us/reader035/viewer/2022070411/56649f295503460f94c43582/html5/thumbnails/35.jpg)
If you miss one, your options are: For 3-credit registrants:1) you can take a zero for the field trip;2) you can drop the course.
For 5-credit registrants:1) you can drop to 3 credits;2) you can take a zero in the missed trip;3) you can drop the course.
![Page 36: Rivers and Beaches (ESS/Ocean 230) Chuck Nittrouer Sarah Schanz 111 Marine Sciences Building / 543-5099 432 Johnson Hall / 206-616-0799 nittroue@uw.edu](https://reader035.vdocuments.us/reader035/viewer/2022070411/56649f295503460f94c43582/html5/thumbnails/36.jpg)
If you need a note explaining your absence from other classes, please contact Chuck at least a week before the trip. (for next Th, need to know now)
Info needed:name of instructor their email address course name and number
Contact Jonathan ([email protected]) to sign-up for Field Trip A on either 8 or 15 Oct.

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.
