Sustainable soil and water resources: modelling soil erosion and its impact on the environment

With the projected increase in world population to 9 billion by 2050, along with per capita income growth, the demand for land and water resources is going to increase significantly. Conversion of land to intensive agriculture has led to dramatic decreases in plant, animal and insect biodiversity, with approximately 40% of the world’s land surface now covered by croplands and pastures. Intensiv...

Stochastic Modelling of Soil Erosion and Deposition

The rate of erosion is the product of the concentration of active soil aggregates and their mean vertical velocity. The sediment concentration for a given time is proportional to the probability of detachment of first-time mobilized soil aggregates and to the probability of the deposited sediments’ redetachment. The probability of soil aggregate activation is equal to the probability of the dri...

On the modelling of internal soil erosion

Suffusion is the process whereby fine particles are moved locally an transported through a coarse layer. This is a bulk erosion, which corresponds to a source term in the mass balance equations. This bulk erosion is counter intuitive, as erosion is basicaly an interfacial process. We suggest a framework within suffusion in a clayey sand can be viewed as a clay/water interface erosion at the mic...
