Effective discharge in monsoon controlled rivers
Amanda Schmidt, Oberlin College
When does a river really carry sediment? Do lots of small floods carry as much sediment as a single big flood? Although we talk about average annual erosion rates, is sediment transport in rivers episodic rather ...

A new deglacial chronology of the Laurentide Ice Sheet in Wisconsin
David Ullman, University of Wisconsin-Madison
During the past 2.5 million years, the earth has seen a series of major ice sheets built through the slow accumulation of snow, followed by warming and rapid ice collapse. This fluctuation in global ice sheets is ...

The retreat chronology of the Laurentide Ice Sheet during the last 10,000 years and implications for deglacial sea-level rise
David Ullman, University of Wisconsin-Madison
Much of the world's population is located along the coasts. In a world of changing climate, the rate of sea level rise will determine the ability of these communities to adapt to sea level rise. Perhaps the ...

Fluvial geomorphology in a tank - The scientific value of physical experiments
Nikki Strong, University of Minnesota-Twin Cities
The beauty and utility of experiments is to illuminate the fundamental processes that drive the evolution of natural systems. Experiments help us build intuition for processes that otherwise might be hard to ...

Marine terraces in mid-latitude settings: the case of the Oregon USA coast
Harvey Kelsey, Humboldt State University
Marine terraces are terraced landforms that occur as elevated flats inboard of, and parallel to, coastlines. Outstanding examples of a stair-step landscape of marine terraces can be found in many places in the ...

The humped soil production function
Arjun Heimsath, Arizona State University at the Tempe Campus
Introduction When you walk across your favorite hill do you ever think about what you're walking on? Ever wonder what's beneath your feet and why it's there? If you've wondered about the soil ...

Challenges associated with investigations into the geomorphology of other worlds: A case study examining glacier-like forms in the mid-latitudes of Mars
Colin Souness
Ever since global imagery of Mars was first gathered and transmitted back to Earth in 1971 by the Mariner 9 orbiter, geomorphologists have remarked upon the abundance of landforms which seem to suggest the action ...

Stream response to Climate Change, Atacama Desert, Chile
Jason A Rech, Craig Tully, Claudio Latorre Miami University, Ohio; Pontificia Universidad Católica de Chile
Climate on earth is constantly changing. Earth's climate can change gradually over millions of years (tectonic-scale) due to changes in greenhouse gases or the slow movement of tectonic plates, or climate can ...

Marine Geomorphology: Geomorphic Processes, Hazards, and Paradoxes in Monterey Canyon
Douglas Smith, California State University-Monterey Bay
Introduction While traditional geomorphic studies focus on the geologic processes and products that shape our terrestrial topography, there are equally exciting opportunities to explore the other 71% of the planet ...

Arroyo Cutting in the Southwestern U.S.
Jonathan Harvey
Introduction In the semiarid southwestern United States, water is extremely important. However, most streams in the region are ephemeral, meaning that they are dry for much of the year and flow only during flash ...
