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 ...

Restoration of the Elwha River system, Washington, through dam removal
Amy Draut
Most of the world's rivers contain one or more dams. On streams and rivers in the U.S. alone there are more than 75,000 dams large enough to store more than one year's runoff capacity, and many more dams ...

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 ...

Landscape inversion on Earth and Mars
Devon Burr, Northern Arizona University
PROCESS: Landscape inversion is the process whereby relative topographic elevations become inverted such that previously low-standing features become high-standing. This relief inversion occurs through induration ...

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 ...

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, ...
