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 ...

Fluvial geomorphology in a tank - The scientific value of physical experiments
Nikki Strong, University of Minnesota-Twin Cities
The beauty and utility of experiments is to illuminate the fundamental processes that drive the evolution of natural systems. Experiments help us build intuition for processes that otherwise might be hard to ...

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 ...

Soil-water-rock interactions I: The pediment problem
Mark Strudley
You may have not initially appreciated that piedmonts (landscapes between steep mountain masses and depositional basins) are not all covered by alluvial fans. In fact, piedmonts, along with adjoining low-relief ...

Predicting the effect of changing climate on landscapes with computer based landscape evolution models
arnaud temme
Predicting the effect of changing climate on landscapes with computer based landscape evolution models. Future climate change will influence the processes that shape our landscapes. Knowing this influence is ...

Understanding soil erosion and landscape evolution using computer based predictive models
Greg Hancock
The ability to measure and model soil erosion and resultant landscape evolution is important because soil erosion has a range of environmental impacts, including loss of organic matter and nutrients, reduction of ...

Impact of deforestation on slope stability
veerle vanacker
Slope movement is a widespread hazard in mountainous regions around the world. Consequently, not only considerable financial costs are suffered, but also major ecological and environmental problems arise in a ...

Vegetation restoration in gully beds enhances sediment deposition
veerle vanacker
Mountain ecosystems in developing countries are suffering from rapid land-use/land-cover change, induced by demographic growth and socio-economic development (Figure 1, Vanacker et al., 2003). Given their steep ...

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

Tillage erosion in developing countries in Asia
ALAN ZIEGLER
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 ...
