Impact of deforestation on slope stability
veerle vanacker
Slope movement is a widespread hazard in mountainous regions around the world. Consequently, not only considerable financial costs are suffered, but also major ecological and environmental problems arise in a ...

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 ...

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 ...

Some useful Non-dimensional Numbers in Geomorphology and the Art of Deriving New Ones
Nikki Strong, University of Minnesota-Twin Cities
Units of Measure One can express physical quantities in terms of many different units of measure and a particular quantity can take on very different numerical values under different unit systems. For example, ...

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 ...

Width convergence in tide-dominated estuaries: the case of the Alligator Rivers, Northern Australia.
Gareth Davies
The Alligator Rivers region is situated in the southeast corner of Van Diemen Gulf, northern Australia (Figure 1). It contains some excellent examples of tide-dominated estuaries (Figure 2). An immediately obvious ...

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 ...
