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 ...

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 ...

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 ...

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 ...

Effects of urbanization on stream channel geometry in the Illinois River watershed in Northwest Arkansas
Amanda Keen-Zebert
The land-use changes associated with urbanization have a range of critical impacts on watersheds, stream geomorphology, and habitat. Much of the thinking about how streams respond to urbanization proliferating ...

Geomorphic Setting & Archaeology of the Cunene River, Namibia
Kathleen Nicoll, University of Utah
Introduction This vignette presents a virtual tour of the Cunene River, and a prehistoric archaeological site located on a fluvial terrace in northern Namibia. Today the Cunene River is an important transnational ...

Adam Parris
The San Francisco Bay – A Community Investment The San Francisco Bay (Bay) is part of the largest estuary on the west coast of North America. It supports a densely populated and prosperous surrounding cultural ...

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 ...

Cold climate conditions as a driver of alluvial fan deposition in the Lost River Range, Idaho, USA
Megan Kenworthy, Center for Ecohydraulics Research, University of Idaho, Boise
Numerous large alluvial fans sit along the western front of the Lost River Range (LRR) in east-central Idaho, USA (Figure 1). These alluvial fans form where streams exit confined basins within the mountain range, ...

Reconstructing the geomorphic history of a cave: a case study from Liang Bua, Indonesia
Kira Westaway
Liang Bua, a large cave situated 16 km from Ruteng in western Flores, Indonesia (Figure 1), was formed as a subterranean chamber over 600 ka. From this time to the present, a series of geomorphic events influenced ...
