Using technology as an aid to the geomorphologist
Sarah Robinson, Arizona State University at the Tempe Campus
Geomorphology requires characterization of the earth's surface at sufficient high resolution in 3 dimensions to explicitly represent landforms. Measuring change requires repeat survey, thus adding the 4th ...

Volcanic History and Cinder Cone Erosion at Newberry Volcano, Oregon
Steve Taylor, Western Oregon University
Surface landforms result from a balance of constructional and erosional processes operating at geological time scales of 102 to 105 years. The landscape evolves over time as masses of earth material are transferred ...

Digital Topography: Should you choose a TIN or raster interpolation of the landscape?
Lisa Walsh, University of Maryland-College Park
The recent explosion of Geographic Information System (GIS) tools enable geoscientists to visualize the Earth's surface in three dimensions using digital topography. Digital topography can be represented in ...

Understanding soil erosion and landscape evolution using computer based predictive models
Greg Hancock
The ability to measure and model soil erosion and resultant landscape evolution is important because soil erosion has a range of environmental impacts, including loss of organic matter and nutrients, reduction of ...

Topographic signatures of lithologies in the Modi Khola valley of central Nepal
Lisa Walsh, University of Maryland-College Park
Rock resistivity to erosion plays a vital role in the evolution of the Earth's topography. Since different rock types exhibit different levels of resistivity to erosion, the more resistant rock types tend to ...

The Occurrence of Small-Scale Debris Fans in Sandstone Landscapes of the Central Appalachians
Steve Taylor, Western Oregon University
Alluvial fans occur in diverse landscapes, and represent critical sites of sediment routing in mountainous watersheds. These radiating, wedge-shaped deposits of sediment are commonly associated with high-energy ...

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 ...

(Sediment) Accounting 101: An Example
Chuck Podolak, Johns Hopkins University
I. Introduction Rivers transport both water and sediment [rock fragments such as sand and gravel] from hillsides to the oceans. As sediment moves downstream it creates river bars, accumulates into floodplains, and ...

A 54-year record of sediment yield linked with proglacial sedimentary dynamics
Martin Geilhausen, Zurich University of Applied Sciences
Proglacial zones are newly formed landscapes in front of or just beyond the outer limits of glaciers (fig. 1). They are out of equilibrium with the current climate and therefore highly sensitive to climate change. ...

Suspended sediment yield from an Alpine proglacial zone - quantification and controls
Martin Geilhausen, Zurich University of Applied Sciences
Proglacial zones are newly-formed landscapes in transition from glacial to non-glacial conditions which are located in front of or just beyond the outer limits of glaciers. In the context of climate change and ...
