Hydrologic and Water Quality Effects
Forest operations such as harvesting, thinning, and site preparation can affect the hydrologic behavior of watersheds on poorly drained soils. The influence of these operations conducted on organic soil sites can be more pronounced than on mineral soil sites due to the differences in bulk density and soil moisture relationships that exist between mineral and organic soils. This article reports ...

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...
متن کاملSustainable 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...
متن کاملOn 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...
