Soil Erosion by Water

A Cellular Automata Model for Soil Erosion by Water

A Cellular Automata model for soil erosion by water, SCAVATU, was developed. It involves a larger number of states in comparison to the previous models: alti-sidering some of the most significant processes of the phenomenon: water flow, infiltration, soil erosion by water flow, sediment transport and deposition. Simulations gave encouraging results, in agreement with the findings of other studi...

Soil Erosion by Water: Contemporary Research Methods and Their Use

According to a UN Environment Programme survey, topsoil is eroding faster than it forms on about one third of the world’s cropland, causing an estimated 85 % of the world s land degradation from human activities. Erosion of soil, mainly by water, is also a problem in the Czech Republic where 54 % of arable land is endangered by water erosion. The topic of this article is to describe contemporar...

Effect of soil composition on critical water erosion shear stress

Soil erosion by assessing hydrothermal conditions of its formation

Soil erosion is one of the vital factors contributing to the loss of fertility and environmental degradation. Generally accepted diagnostics of eroded soils is based on comparison of the sloping soils profile depth with the watershed soils. In this case, there is a separate problem of slope soils with a naturally shortened profile and eroded soils. Formation of the soil’s natura...
