Vignettes are stand-alone, illustrated electronic case studies that teach about geomorphology, surface processes, and/or Quaternary history. Vignettes can be used alone or in combination with the "Key Concepts in Geomorphology", the first in a new generation of textbooks. Vignettes allow faculty to customize the learning resources they offer students to enrich and personalize student learning experiences.

Using technology as an aid to the geomorphologist
Sarah Robinson, Arizona State University at the Tempe Campus
Geomorphology requires characterization of the earth's surface at sufficient high resolution in 3 dimensions to explicitly represent landforms. Measuring change requires repeat survey, thus adding the 4th ...

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 ...

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 ...

A general bedload transport equation for homogeneous grains
Peng Gao, Syracuse University
Bed load is one of two types of sediment load (the other one suspended load) transported in natural rivers (Fig. 1) and is originated from channel bed or banks. Although it only takes about 5% to 20% of the total ...

Digital Topography: Should you choose a TIN or raster interpolation of the landscape?
Lisa Walsh, University of Maryland-College Park
The recent explosion of Geographic Information System (GIS) tools enable geoscientists to visualize the Earth's surface in three dimensions using digital topography. Digital topography can be represented in ...

Soil-water-rock interactions I: The pediment problem
Mark Strudley
You may have not initially appreciated that piedmonts (landscapes between steep mountain masses and depositional basins) are not all covered by alluvial fans. In fact, piedmonts, along with adjoining low-relief ...

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 ...

Understanding soil erosion and landscape evolution using computer based predictive models
Greg Hancock
The ability to measure and model soil erosion and resultant landscape evolution is important because soil erosion has a range of environmental impacts, including loss of organic matter and nutrients, reduction of ...

Impact of deforestation on slope stability
veerle vanacker
Slope movement is a widespread hazard in mountainous regions around the world. Consequently, not only considerable financial costs are suffered, but also major ecological and environmental problems arise in a ...
