Measuring wind erosion is difficult as it requires the coincidence of a rare wind event with soil conditions that allow erosion. There is not necessarily a distinct threshold velocity; the relative force of the wind and the fluffiness of the soil
determine whether erosion will occur. The relative importance of stable/unstable surface elements may be determined by analysing the wind profile. Lastly, a model of suspension with saltation has evolved; it suggests that saltation is not distinctly
Wind and waves: influence of local and non-local waves on mesoscale beach behavior in estuarine environments

A 29-day field investigation was conducted on a meso-tidal sand beach in Delaware Bay, New Jersey to document the contribution of local estuarine and non-local ocean waves to beach recovery following storms. Data were gathered on winds, waves, flow

A series of micro-erosion-meter sites on different rock types and in differing wind regimes was established and re-read after four years on two sites in the Larsemann and Vestfold Hills. These two oases in Eastern Antarctica are subjected to both

In this paper more than 4000 hourly wind profiles measured on three different sites (Wadden islands, Mainland coast and Zeeland estuaries in the Netherlands) are analysed and discussed. Reference is made to both field and simulation studies (either
using wind tunnel models or numerical computer models).

This study reports on a series of wind tunnel experiments in which rapid, detailed measurements of the sediment flux, wind profile and surface geometry were made, as the number and exposure of non-erodible roughness elements increased on test
Wind tunnel experiments and field measurements of aeolian dust deposition on conical hills
The spatial pattern of short-term aeolian dust deposition on and around cone-shaped hills is investigated via the simulation, in a wind tunnel, of dust storms over a topographic scale model of a conical hill in the Negev desert, Israel. The results
Late Quaternary vegetation and climate of the Wind River Range, Wyoming
Sediments from Rapid Lake document glacial and vegetation history in the Temple Lake valley of the Wind River Range, Wyoming over the past 11,000 to 12,000 yr. Radiocarbon age determinations on basal detrital organic matter from Rapid Lake

The vertical distributions of grain-size parameters of drifting sand flux during sand storms in the Taklamakan Desert, were investigated through field observation and laboratory wind-tunnel tests. The results show that grain-size parameters
of the drifting sands near the ground surface are similar to those of the source deposits. Regional differences in the vertical distribution of grain-size compositions are affected by source deposits, wind speeds, and transport rates, but source has more influence
on the sorting of the drifting material that wind velocity.
