Some useful Non-dimensional Numbers in Geomorphology and the Art of Deriving New Ones
Nikki Strong, University of Minnesota-Twin Cities
Units of Measure One can express physical quantities in terms of many different units of measure and a particular quantity can take on very different numerical values under different unit systems. For example, ...

The Occurrence of Small-Scale Debris Fans in Sandstone Landscapes of the Central Appalachians
Steve Taylor, Western Oregon University
Alluvial fans occur in diverse landscapes, and represent critical sites of sediment routing in mountainous watersheds. These radiating, wedge-shaped deposits of sediment are commonly associated with high-energy ...

(Sediment) Accounting 101: An Example
Chuck Podolak, Johns Hopkins University
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 ...

Width convergence in tide-dominated estuaries: the case of the Alligator Rivers, Northern Australia.
Gareth Davies
The Alligator Rivers region is situated in the southeast corner of Van Diemen Gulf, northern Australia (Figure 1). It contains some excellent examples of tide-dominated estuaries (Figure 2). An immediately obvious ...

A 54-year record of sediment yield linked with proglacial sedimentary dynamics
Martin Geilhausen, Zurich University of Applied Sciences
Proglacial zones are newly formed landscapes in front of or just beyond the outer limits of glaciers (fig. 1). They are out of equilibrium with the current climate and therefore highly sensitive to climate change. ...

Suspended sediment yield from an Alpine proglacial zone - quantification and controls
Martin Geilhausen, Zurich University of Applied Sciences
Proglacial zones are newly-formed landscapes in transition from glacial to non-glacial conditions which are located in front of or just beyond the outer limits of glaciers. In the context of climate change and ...

Cosmogenic nuclide inventories of river sediments reveal the geomorphic character of their source areas
Alexandru T Codilean
The realization that surface processes can play a key role in moderating tectonics, and possibly climate (Molnar & England, 1990; Raymo & Ruddiman, 1992; see also Bishop 2007) has meant that there is now a ...

A sediment budget for an area of sugarcane cultivation on the Herbert River floodplain, NE Australia
Fleur Visser
While demand on food production is growing, agricultural land is becoming increasingly less productive because of the erosion of fertile topsoil. The effects of soil erosion, however, go beyond the loss of fertile ...

Soil-water-rock interactions II: The formation of tors in arid and semiarid environments
Mark Strudley
The prominence of bedrock edifices above essentially featureless, erosional pediment surfaces underscores the crux of the 'pediment problem' that has baffled geologists since 1877(described in the Part I ...
