Landscape inversion on Earth and Mars
Devon Burr, Northern Arizona University

A general bedload transport equation for homogeneous grains
Peng Gao, Syracuse University
Bed load is one of two types of sediment load (the other one suspended load) transported in natural rivers (Fig. 1) and is originated from channel bed or banks. Although it only takes about 5% to 20% of the total ...

Digital Topography: Should you choose a TIN or raster interpolation of the landscape?

Introduction The Tigris is one of Antiquity's famous rivers, as it flanks the fertile strip of land known as the Mesopotamian Plain, the heartland of the mighty biblical empires of Sumeria and Assyria (Figure ...

Use of Large Woody Materials and Large Wood in Streambank Erosion Control
Frank Reckendorf
In recent years, woody material has been used to add a habitat component to the use of woody materials for bank protection. However, the use of large woody materials for bank protection has a long history. Use of ...

Causes of Streambank Erosion
Frank Reckendorf
Streambank erosion is a natural phenomenon but can become accelerated because of changes at the watershed and/or reach level. Background conditions are established using old photographs and maps and compare rates ...

Soil flowed over the slopes of KwaZulu Natal in South Africa about 30,000 years ago
arnaud temme
Several landscape processes cause the movement of soil over slopes. Erosion from overland water flow and sudden landsliding are among the best-known of these processes. Creep, the slow and depth-dependent movement ...

When a tree falls in the forest, does it make a soil?
Emmanuel Gabet, San Jose State University
When a Tree Falls Over A tree, like most plants, sends roots down into soil and bedrock to absorb water and nutrients. The roots also anchor the tree to the ground and prevents it from tipping over. Strong wind ...
