Geomorphic history controls the locations of fresh-water wetlands on barrier islands, Virginia's Atlantic shore
Rich Whittecar, Old Dominion University
Fresh-water ponds on low sand islands Native Americans, pirates and the early European colonists used them. Ship-wreaked sailors owe their survival to them. Fresh-water ponds somehow seem out of place, though, ...

Rock glaciers: their ice and debris balances
Brian Whalley, niversity of Sheffield
Rock glaciers are best defined by their topography (Fig. 1) and that they flow slowly. Their dynamic character is attributed to the flow of ice deforming the associated weathered rock debris. Typically, they flow ...

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 ...

Human-Induced Floodplain Sedimentation in the Driftless Area of southwestern Wisconsin: Consequences on Riparian Ecosystems
Eric Booth, University of Wisconsin-Madison
The Driftless Area of southwestern Wisconsin (Figure 1) is a unique region in the Upper Midwest, USA, because it escaped the direct effects of continental glaciation. In contrast, surrounding areas have been ...

Influence of Dam Operations on Geomorphology and Sediment in the Colorado River corridor, Grand Canyon National Park, Arizona
Amy Draut
Large dams can greatly alter the physical and biological environments of rivers, by changing the magnitude and timing of flows, sediment transport, and water temperature. One of the most iconic landscapes in the ...

Automatic extraction of flow paths from digital elevation models
Kyungrock Paik, Korea University
Once a raindrop falls on the ground, it flows downward. During this journey, the raindrop joins other raindrops and the mass/volume of the water increases, flowing along creeks, streams, and rivers. This is called ...

Development of Palimpsest Landscapes
Jasper Knight
In Physical Geography, a palimpsest landscape is one where, in any given region, the different landforms that make up the landscape are not of the same age, with some surface landforms being very young because they ...

gail ashley, Rutgers University-New Brunswick
Introduction Wetlands are an important water resource in arid regions (<400 mm annual precipitation) and may also provide grazing opportunities for farm animals. Permanent freshwater wetlands are also important ...
