Soil Erosion Control and Soil Conservation Using Geosynthetics – IGS UK Webinar
The talk will first consider the problem of soil erosion, defined as the detachment and transport of soil or other slope forming materials at the ground surface. It will cover the causes, extent, severity and consequences of soil erosion in the UK, and why soil erosion control is so important for environmental and regulatory reasons. Knowing why slope-forming materials erode at different rates helps target the application of erosion control measures such as the use of vegetation and geosynthetics.
Geosynthetics (including synthetic and natural products) are used in surface erosion control “to prevent or limit soil or other particle movements at the surface of, for example, a slope” (ISO 10318). Whilst the use of geosynthetics has expanded, scientific understanding of how these products affect the hydrological and hydraulic processes operating on a slope is limited. Cranfield University has undertaken geosynthetic product evaluation for over 30 years, using a range of environmental scenarios. The aim is to find the salient properties of cost-effective geosynthetics for short-term and long-term erosion control, including their ability to support vegetation cover. This information can inform a) site managers and contractors in selecting appropriate products and b) product designers and manufacturers in creating innovative erosion control products.
