Denudation rate chronologies and the topographic development of the San Bernardino Mountains, California
William Phillips
How does the topography of mountains develop? What roles do crustal processes such as faulting and surface processes such as erosion play? These questions have long been a focus of geomorphic research. In the past ...

Eolian Landforms and Deposits of the Eastern Snake River Plain, Idaho
William Phillips
The Eastern Snake River Plain (ESRP) is a northeast-trending, 300 kilometer-long depression underlain by Cenozoic volcanic rocks (Fig. 1). Well-known for many examples of volcanic landforms including basalt lava ...

Human Impacts on the Landscape
Roger Hooke
Humans move tremendous amounts of earth every year. They are arguably the premier geomorphic agent sculpting the surface of Earth today. In the early 1990s, people in the United States were moving about 0.8 Gt (Gt ...

Processes and rates of channel change following disturbance by debris flows
Christine May
The Oregon Coast Range is a dynamic landscape, with steep hillslopes mantled by a thin veneer of soil. In this and other mountainous regions of the world, debris flows play a major role in routing sediment and ...

Comparative planetology: the geomorphology of volatile cycling and catastrophic flooding
Devon Burr, University of Tennessee, The
INTRODUCTION: Three planetary bodies in our Solar System show landforms that provide evidence of liquid flowing over the surface, either at present or in the past. The surface flow of liquid is evidence for a ...

Historic influences on modern bank erosion: A case study in Crabbs Branch, Maryland
Karen Jennings
Streams are complex systems that continually evolve to accommodate changes in the amounts of water and sediment supplied from the watershed. Land use changes in a watershed can have large impacts on watershed ...

Natural Storm Variability in New England
Adam Parris
Why storms? Climate is the long-term average of variables in the Earth's atmosphere, such as temperature, precipitation, and wind. For millions of years, climatic events, such as rainstorms, have shaped the ...

The retreat chronology of the Laurentide Ice Sheet during the last 10,000 years and implications for deglacial sea-level rise
David Ullman
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 ...
