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 ...

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 ...

Slow erosion without creep in the McMurdo Dry Valleys, Antarctica
Dan Morgan, Vanderbilt University
Quantifying erosion rates is central to understanding how landscapes evolve through time and for discerning the links between landforms and the processes that shape them. The alpine valleys of the McMurdo Dry ...

The Mexican Alps: A Zone of Glacier Carved Cirques and Valleys
Winston Crausaz
BACKGROUND The Mexican Alps is a zone of spectacular landforms similar to those found in the glaciated regions of the Rocky Mountains. It is located just north of Mexico's highest mountain, Pico de Orizaba, ...

Natural Storm Variability in New England
Adam Parris
Why storms? Climate is the long-term average of variables in the Earth's atmosphere, such as temperature, precipitation, and wind. For millions of years, climatic events, such as rainstorms, have shaped the ...

What's in a fan?: A closer look at the stratigraphy of five Vermont Alluvial Fans
Karen Jennings
An alluvial fan is a cone-shaped accumulation of water-deposited sediment, formed at the interface between steep hillslopes and flat valleys where streams exit confined channels. Alluvial fans act as repositories ...

Impacts of upland land management on sediment dynamics in the Pontbren catchment, mid-Wales, UK
Alex Henshaw
Changes in vegetation, soil structure, surface topography and drainage associated with land management practices can affect the intensity and spatial distribution of runoff generation, erosion and sediment supply ...

Assessing Future Flood Risks in the Taihu Basin, East China
Gemma Harvey
The past decade has seen a significant transition in the management of fluvial and coastal flood risks from flood 'defence' (employing 'hard engineering' measures such as flood embankments, ...

Alluvial Fans and Archaeological Sites on the East Range of Fort Huachuca Military Reservation, SE Arizona
Michael Droz
Introduction In the American Southwest, a ubiquitous and recognizable geomorphic landscape feature is the bajada, consisting of a series of broad, laterally coalesced alluvial fans. These alluvial aprons emerging ...

Comparative planetology: the geomorphology of volatile cycling and catastrophic flooding
Devon Burr, Northern Arizona University
INTRODUCTION: Three planetary bodies in our Solar System show landforms that provide evidence of liquid flowing over the surface, either at present or in the past. The surface flow of liquid is evidence for a ...
