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 ...

Effective discharge in monsoon controlled rivers
Amanda Schmidt, Oberlin College
When does a river really carry sediment? Do lots of small floods carry as much sediment as a single big flood? Although we talk about average annual erosion rates, is sediment transport in rivers episodic rather ...

Fluvial geomorphology in a tank - The scientific value of physical experiments
Nikki Strong, University of Minnesota-Twin Cities
The beauty and utility of experiments is to illuminate the fundamental processes that drive the evolution of natural systems. Experiments help us build intuition for processes that otherwise might be hard to ...

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 ...

Some useful Non-dimensional Numbers in Geomorphology and the Art of Deriving New Ones
Nikki Strong, University of Minnesota-Twin Cities
Units of Measure One can express physical quantities in terms of many different units of measure and a particular quantity can take on very different numerical values under different unit systems. For example, ...

Marine Geomorphology: Geomorphic Processes, Hazards, and Paradoxes in Monterey Canyon
Douglas Smith, California State University-Monterey Bay
Introduction While traditional geomorphic studies focus on the geologic processes and products that shape our terrestrial topography, there are equally exciting opportunities to explore the other 71% of the planet ...

A 54-year record of sediment yield linked with proglacial sedimentary dynamics
Martin Geilhausen, Zurich University of Applied Sciences
Proglacial zones are newly formed landscapes in front of or just beyond the outer limits of glaciers (fig. 1). They are out of equilibrium with the current climate and therefore highly sensitive to climate change. ...

Cosmogenic nuclide inventories of river sediments reveal the geomorphic character of their source areas
Alexandru T Codilean
The realization that surface processes can play a key role in moderating tectonics, and possibly climate (Molnar & England, 1990; Raymo & Ruddiman, 1992; see also Bishop 2007) has meant that there is now a ...

A sediment budget for an area of sugarcane cultivation on the Herbert River floodplain, NE Australia
Fleur Visser
While demand on food production is growing, agricultural land is becoming increasingly less productive because of the erosion of fertile topsoil. The effects of soil erosion, however, go beyond the loss of fertile ...
