Rock Glaciers Move Mountains - Perhaps Right Under Your Skis
Twila Moon, University of Washington-Bothell Campus
What is a Rock Glacier?A rock glacier is an geomorphic feature that includes ice and talus. An "active" rock glacier meets two important criteria: 1) it contains ice currently and 2) it is moving and ...

Application of remote sensing in geomorphology
MATTHEW BLACKETT
Remote sensing is the observation of surfaces or objects while not being in direct contact with them. By this definition, cameras are remote sensors, observing the environment around us but not requiring us to ...

The shaping of England's Peak District National Park
MATTHEW BLACKETT
The Peak District is a National Park in central England (Figure 1), characterized by a unique geology and geomorphology which are the product of processes extending back to the Late Tertiary period, approximately ...

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 ...

Lightning as a Geomorphic Agent in Low-Latitude Mountains
Jasper Knight
It is often assumed that high mountain environments are dominated by the geomorphic imprints of cold-climate weathering and erosion processes, forming angular bedrock fragments that are commonly found across ...

Erodibility, tensile strength, and the "k" problem in Grand kanyon
Natalie Bursztyn, University of Montana
River profile shape is an important indicator of the geomorphic processes and history that contributed to its modern form. In the case of bedrock streams during episodes of incision, resistance of river-level ...
