Landscape or Land Use? Documenting Influences on Fine Sediment Yield in a Logged New England Watershed
Alan Kasprak
The type and intensity of land use in a watershed can considerably impact the form of channels within the basin. Of particular note with regard to land use are (A) the shifts in the amount of water reaching ...

Luminescence dating used to reconstruct fault slip rates in the Mojave Desert, California
Belinda Roder
The Mojave Desert, California, is crossed by a number of major active fault systems that have played an important role in this region's landscape development and represent a significant seismic hazard to ...

Floodplain chronology of the Stillerust Vlei, Mooi River floodplain wetland, in western KwaZulu-Natal, South Africa
Amanda Keen-Zebert
Wetlands have become a focus of conservation efforts worldwide following the international Ramsar Convention (The Convention on Wetlands of International Importance) established in 1971. Wetlands are areas where ...

Quaternary glaciation of the Himalaya and Tibet
Lewis Owen, University of Cincinnati-Main Campus
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 ...

Uplift rates and vertical fault displacements derived from marine terraces, Crete, Greece
Sean Gallen, North Carolina State University at Raleigh
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 ...

Spatial and temporal geomorphic variability in fluvial systems: A case study from the Conejos River, Colorado
Anthony Layzell, University of Kansas Main Campus
Effective and sustainable river management requires an understanding of how fluvial processes vary both spatially and temporally (e.g. Wohl et al., 2005). This is important because rivers are capable of alternating ...

Soil geomorphology and change over time: A case study from the Catawba River, North Carolina
Anthony Layzell, University of Kansas Main Campus
Despite their value in Quaternary studies, relatively few soil chronosequences or long-term landscape evolution studies exist for the Piedmont physiographic province of the southeastern United States. Investigating ...

The influence of weathering and soils on the geomorphic expression of tectonic landforms: an exception to a rule of tectonic geomorphology
Martha Eppes
Background Blind Thrust Faults and Seismic Hazard In southern California, one of the most tectonically active regions of the United States, it is critical to understand the potential earthquake hazard that ...

A new deglacial chronology of the Laurentide Ice Sheet in Wisconsin
David Ullman
During the past 2.5 million years, the earth has seen a series of major ice sheets built through the slow accumulation of snow, followed by warming and rapid ice collapse. This fluctuation in global ice sheets is ...

Fire geomorphology: Interactions among climate, fire, and vegetation
Kerry Riley
In steep forested landscapes, fire plays a crucial role in the timing and magnitude of erosion. Fire is a natural disturbance to vegetation and surface erosion and is a primary driver of ecosystem change across the ...
