Vignettes

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.

Radiocarbon calibration
Quan Hua
Radiocarbon dating is one of the most reliable and well-established methods for dating the Holocene and Late Pleistocene. Natural radiocarbon or 14C is produced in the atmosphere by the interaction of the secondary ...

Catastrophic glacial-lake outburst spillways: form and process relationships.
Alan Kehew
Proglacial Lake outbursts along the southern margins of the Laurentide Ice Sheet As the Laurentide Ice Sheet retreated northward through the Great Plains and midwest area of North America, meltwater drainage ...

Tunnel Channels of the Saginaw Lobe, Michigan, USA
Alan Kehew
Introduction Drainage of meltwater from a glacier occurs at the surface of the glacier, as well as internally and between the ice and its bed. Different components of the meltwater drainage system commonly ...

Fluvial terrace history, Kings Creek, Manhattan, Kansas
charles oviatt
Natural cutbank exposures along streams can provide information about the geomorphic history of the stream valley. In a fluvial system, extrinsic factors, such as climate, tectonics, or land use, can lead to ...

The Snowplow, Lake Bonneville, Utah
charles oviatt
Lake Bonneville was the largest of the late Pleistocene lakes in the Great Basin of western North America (Fig. 1). It occupied the basin of modern Great Salt Lake and was hydrographically closed during its ...

(Sediment) Accounting 101: An Example
Chuck Podolak
I. Introduction Rivers transport both water and sediment [rock fragments such as sand and gravel] from hillsides to the oceans. As sediment moves downstream it creates river bars, accumulates into floodplains, and ...

An Example of One River's Response to a Large Dam Removal
Chuck Podolak
Damming a river can provide hydropower, water storage, and/or flood control, but at the same time may have adverse effects on fish and other aquatic species, flood land behind a dam, or degrade a river downstream ...

Glacier Fluctuations Since the Last Glacial Maximum in Southwest Alaska
Jonathan Harvey
Glacier fluctuations since the last glacial maximum in southwest Alaska Introduction During the last glacial maximum (LGM), alpine glaciers in the western cordillera expanded, coalesced, and flowed onto ...

Arroyo Cutting in the Southwestern U.S.
Jonathan Harvey
Introduction In the semiarid southwestern United States, water is extremely important. However, most streams in the region are ephemeral, meaning that they are dry for much of the year and flow only during flash ...

Coastal Geomorphology and Policy Applications along Southern Monterey Bay, California
Douglas Smith
Introduction Global sea level stood between 100 m and 130 m lower than today's sea level 18,000 years ago at the peak of the latest ice age. Since that time, melting ice and thermally expanding oceans have ...
