Reduction of erosion and sediment‐related pollution from urban construction sites or other degraded hillslopes often relies on the initial application of suitable rolled erosion control systems (RECS) before natural vegetation cover can be established. However, research has not clearly explained why some RECS perform better than others, or under what particular conditions one system is more suitable than another. An important link between the application of the most suitable RECS and better product design is process‐based studies relating the physical properties of products to the reduction of erosion subprocesses. This study investigates time‐varying reduction of rainsplash detachment and transport by 13 commonly used RECS. The results indicate that product differences in the protection they provide against splash processes vary over the duration of a rain event, and that this variation is related to individual product properties, especially surface coverage and thickness. These results should aid in the design of more effective erosion control products and in the selection of the most suitable RECS for particular hillslope applications. © 1997 John Wiley & Sons, Ltd.
