Water demand prediction by end-use at an appropriate spatial and temporal resolution is essential for planning water supply systems that will supply water from a diversified set of sources on a fit-for-purpose basis. Understanding seasonal, daily and sub-daily water demand including peak demand by end-uses is an essential planning requirement to implement a fit-for-purpose water supply strategy...

The yield of an urban water supply system is defined as the average annual volume of water that can be supplied from the water supply system over a given planning period, subject to streamflow variability, operating rules and demand pattern, without violating the adopted level of service. Since yield plays a key role in the management of urban water supply systems, it is important for water aut...
