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 ...

Tillage erosion in developing countries in Asia
Tillage erosion, which is the net redistribution of soil within the landscape as a result of farming activities, is one of the most important soil degradation processes on sloping croplands world-wide (Govers et ...

Erodibility, tensile strength, and the "k" problem in Grand kanyon
Natalie Bursztyn, Utah State University
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 ...

Development of Palimpsest Landscapes
In Physical Geography, a palimpsest landscape is one where, in any given region, the different landforms that make up the landscape are not of the same age, with some surface landforms being very young because they ...

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 ...

Human-Induced Floodplain Sedimentation in the Driftless Area of southwestern Wisconsin: Consequences on Riparian Ecosystems
The Driftless Area of southwestern Wisconsin (Figure 1) is a unique region in the Upper Midwest, USA, because it escaped the direct effects of continental glaciation. In contrast, surrounding areas have been ...

The Drying of Sierra Nevada Wet Meadows Impacted by Channel Incision and Opportunities for Restoration
The Connection Between Groundwater and Stream Channels: When considering the water cycle of a watershed, stream valleys represent a zone where terrestrial and aquatic ecosystems interact through the exchange of ...

How is Everglades geomorphology like that of arid Australian rivers and boreal bogs?
Clues from patternsGeormorphic patterns are interesting not just because of the sense of wonder they evoke, but because they provide evidence of a delicate balance created by feedback. If that feedback is ...

Beach replenishment on developed shorelines: a coupled humanlandscape system
Beach replenishment (also called "beach nourishment") is an engineering strategy commonly used on sandy shorelines where erosion threatens coastal property and infrastructure. The process involves ...
