In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage. Erosion, whether it is by water, wind or tillage, involves three distinct actions – soil detachment, movement and deposition. Soil erosion is, at its core, a natural process. Simply put, it is when topsoil, which is the upper-most layer of the ground, is moved from one spot to another.

These channels can be up to 30cm deep and cause detachment and transportation of soil particles. Rill erosion can eventually evolve into gully erosion. That is when the rills become at least 0.3m deep. Gully Erosion Hitta perfekta Soil Erosion bilder och redaktionellt nyhetsbildmaterial hos Getty Images.

Soil erosion decreases agricultural productivity, degrades ecosystem functions, amplifies hydrogeological risk such as landslides or floods, causes significant losses in biodiversity, damage to urban infrastructure and, in severe cases, leads to displacement of human ADVERTISEMENTS: This article throws light upon the top five engineering measures to help control soil erosion. The engineering measures are: 1. Bunding 2. Terracing 3.
