Laboratory tests for evaluating the performance of geosynthetics for surface erosion control

The objective of this paper is to describe laboratory tests that are currently under development for evaluating the properties of geosynthetics for surface erosion control. Tests that are described have been listed in prEN 00189224 produced by CEN/TC189 project group SURFACE EROSION CONTROL entitled Geosynthetics – Characteristics required for use in surface erosion control on slopes and banks. These include rain simulation. A literature review will be presented. The effect of various parameters like rain intensity, slope of the testing device, soil used in the test will be described as far as possible based on the existing data.
