PROJECT 9 - URBAN DRAINAGE SYSTEM HYDRAULICS

Current practice in Australia for the design of piped urban drainage systems is to consider flow in the pipe as being steady with the pipe flowing full and under pressure; an approach recommended by both Argue (1986) and O'Loughlin and Robinson (1987). The suggested advantages for the currently recommended approach include the inclusion of:

Inherent in this approach, as discussed by Ball (2001), is the assumption that the drainage flows can enter freely the subsurface drainage network. Factors that may negate this assumption include:

Since the last revision of Australian Rainfall and Runoff there have been a number of studies examined these issues with a resultant need to incorporate the results of these studies into Australian Rainfall and Runoff.
