Use of the 2-year, 6-hour rainfall in the design of erosion control works

The design of soil erosion control works often involves the use of the revised universal soil loss equation to estimate potential soil loss (Renard et al, 1991) and the rational method to estimate peak f ows (eg. Landcom, 2004). Both these methods require the use of design rainfall intensities but for different purposes. This paper clarif es the use of design rainfall in these approaches, identif es where confusion may occur, and suggests an approach that is consistent with current engineering guidelines.
