Typically, the kinetic energy rate is calculated based on terminal velocity of vertically falling raindrop...

erosion is considered as a main problem for the loss of arable land around the world. as the world arable land is reaching its limit, marginal areas, such as those prone to wind erosion, have gained importance for agricultural use. a simple and effective way of restoring wind eroded soils is addition of organic materials. sewage sludge can be an effective way to solve this problem. the effect o...

Soil erosion is a growing challenge for agricultural production in Northern China. To explore the effect of variation in stubble height and mulching biomass on soil erosion caused by wind, we conducted a field experiment using a quadratic rotation combination design. Results showed that the quantity of straw mulch was the dominant factor affecting soil erosion, and stubble height was of seconda...

erosion by wind is one of the most important factors in desert environment. prevailing winds can shift sand dunes and affect their accumulation. also, wind regime determines the direction of sand dune mobility. the aim of this research was to investigate sand drift potential using sand movement models. for this research, wind data between 1986 and 2005 from the meteorological station of yazd we...

the objectives of this study were to understand the rainfall characteristics of thewind-water erosion crisscross region on the northern loess plateau, china, to provide basisfor the studies on mitigation of soil erosion, estimation on surface water resources andlocal hydrological circle, etc. the liudaogou catchment with representative climatic andhydrologic conditions of wind-water erosion cri...

Recently disturbed and ‘control’ (i.e. less recently disturbed) soils in the Mojave Desert were compared for their vulnerability to wind erosion, using a wind tunnel, before and after being experimentally trampled. Before trampling, control sites had greater cyanobacterial biomass, soil surface stability, threshold friction velocities (TFV; i.e. the wind speed required to move soil particles), ...

The major topographic features of the martian polar layered deposits include the conspicuous spiral troughs, subtle undulations, broad reentrants (chasma), steep, arcuate scarps, and dune fields. A prominent role for eolian processes in the formation of all of these features is proposed. Strong katabatic winds occur on the north polar cap, producing widespread frost streaks. These cold drainage...
