The focal point of this project is the development of appropriate advice for the use of continuous simulation techniques as a technique for the development of point flow estimates with a given frequency or the development of a system performance estimate. While there have been a number of pilot studies that have developed alternative approaches (see, for example, Boughton et al., 1999; Droop and Boughton, 2003; Jung and Bae, 2005; and Newton and Walton 2000), a consistent and coherent approach has not resulted.
