This paper presents the first results of a project that aims to determine the significance of wind action in the erosion of upland peat. Wind erosion monitoring is being undertaken at Moor House in the North Pennines on a 3-ha area of relatively

The study area is in the county of Suffolk, in east Anglia. A total of 148 samples were taken and their analysis was used to produce a variogram of the spatial variation in 137Cs. The spatial variation of wind erosion and deposition processes
are considered and the implications of the extent and magnitude of soil flux by wind is discussed. Some implications for future large-area assessment of soil flux rates are considered in the light of the findings.

This paper presents a model to integrate windbreak shelter effects into a Geographic Information System (GIS). The GIS procedure incorporates the 1999 version windbreak sub-model of the Wind Erosion Prediction System (WEPS). Windbreak shelter
is modeled in terms of friction velocity reduction, which is a function of wind speed and direction, distance from the barrier, windbreak height, porosity, width, and orientation. A first application of the model was conducted at a study area

The co-ordinated European research project Wind Erosion and Loss of SOil Nutrients in semiarid Spain (WELSONS) was carried out from 1996 to 1999 to understand and predict the potential impacts of land-use change and management on soil degradation
by wind erosion on agricultural land in Central Aragon. This paper gives an overview of the main results regarding the effects of agricultural practices (i.e. conventional, CT, versus reduced tillage, RT) on surface conditions affecting wind erosion
