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 ...

A decade of stream response to the La Valle Dam removal, Baraboo River, Wisconsin
Samantha Greene, University of Wisconsin-Madison
During Euro-American settlement throughout the United States, settlers built milldams along streams to harness energy. Often, the construction of a milldam improved the economic future of the community. These dams ...

Cracking up: emerging evidence for the importance of the sun in the mechanical weathering of rocks
Martha Eppes, University of North Carolina at Charlotte
Introduction Physical weathering, through the breakdown of rock into sediment, plays a fundamental role in the rock cycle and potentially a key role in landscape evolution. In addition, the physical breakdown of ...

Uplift rates and vertical fault displacements derived from marine terraces, Crete, Greece
Sean Gallen, Colorado State University
Introduction: Long-lived and continuing uplift and pervasive extensional faulting are a testament to the active tectonics of the island of Crete, located in the eastern Mediterranean (Figure 1). Large earthquakes ...

Knickpoint migration and landscape evolution, Cullasaja River Basin, North Carolina
Sean Gallen, Colorado State University
Introduction: Localized high topographic relief, steep slopes, and frequent mass wasting — features commonly associated with tectonically active settings — characterize the landscapes of the southern ...

Defining rates of erosion using terrestrial cosmogenic nuclides in the Himalaya
Lewis Owen, North Carolina State University
The Himalaya and Tibet comprise the greatest mountain mass on our planet, stretching for ~ 2000 km east-west and >1500 km north-south with an average elevation of ~5000 m above sea level. The mountain mass ...

Quaternary glaciation of the Himalaya and Tibet
Lewis Owen, North Carolina State University
The mountains of the Himalaya and Tibet are the most glaciated regions outside of the polar realm. The countries within and bordering the Himalaya and Tibet depend greatly on the glacial and associated hydrological ...
