Soil in Motion ... 7
A recently-developed tool used to evaluate soil erosion is the Water Erosion Prediction Project (WEPP) -- a new generation runoff and erosion prediction technology created by the USDA-ARS. WEPP is a process-oriented, continuous simulation model that predicts erosion from a hill slope or small watershed.

X-ray Vision ... 9
McGill University researchers are using X-ray CAT scanning -- typically used for detecting tumors in humans -- to find macropores in soil and watch liquids flow through them without disturbing the soil.

The Big Freeze -- and Thaw ... 11
Although water erosion is recognized as a serious problem, freezing and thawing effects on soil detachment and transport remain one of the least understood aspects of the physical erosion process.

In the Trenches ... 13
The Integrated Training Area Management Program at Fort Riley, Kan., is testing the Water Erosion Prediction Project (WEPP) watershed model's applicability and adaptability to predict soil loss and surface runoff from military training lands.

Last Word (reader opinion) - Responsible Forestry ... 33
Computer models suggest that the magnitude of erosivity changes caused partly by greenhouse gas emissions will increase throughout the century. The magnitude of climate change impacts on erosivity is still in question. However, study results provide a good indication that significant erosivity changes are likely to occur.
Some of the possible effects are being evaluated using more detailed simulation models. The results will help plan better conservation strategies, lead to better, more targeted conservation strategies and develop a better soil resource base for growing food in the United States.
