Soil erosion risk assessment at the watershed of Alqueva is urgently needed to conserve water resources and prevent the accelerated dam siltation. The variation of soil properties is one of the most important reasons for the spatial variability of vegetation cover and erosion. In order to achieve more and better management of rangelands around the largest reservoir of Europe, it is essential to...

Internal erosion is known as the most important cause of dam failure after overtopping. It is important to improve the erosion resistance of the erodible soil by selecting an effective technique along with the reasonable costs. To prevent internal erosion of embankment dams the use of chemical stabilizers that reduce the soil erodibility potential is highly recommended. In the present study, a ...

Global atmospheric dust is simulated using DEAD (Dust Entrainment and Deposition model) in combination with the global scale Oslo CTM2 using meteorological data for 1996. Dust sources are calculated both using mean wind speeds with model resolution (T63) and sub-grid wind speeds. Different datasets are used to describe soil erodibility. We explain how the different assumptions on dust productio...

introduction: globally, soil erosion is a principal degradation process resulting in negative impacts on different soil functions (food and other biomass production, water storing, filtering and transformation, habitat and gene pool, physical and cultural environment for mankind, and source of raw materials) which ultimately causes irreversible effect on the poorly renewable soil resource. dete...

To improve wind erosion model calculations across several spatial and temporal scales simultaneously, there is a requirement for a noninvasive approach that can be used rapidly to assess changes in the compositional and structural nature of a soil surface in time and space. Remote sensing allows consideration of the processes controlling erodibility on the same spatial continuum to avoid time-c...
