This paper presents reliability, water demand and economic analysis of rainwater harvesting (RWH) systems for eight Australian capital cities (Adelaide, Brisbane, Canberra, Darwin, Hobart, Melbourne, Perth and Sydney). A Python-based tool is developed based on a daily water balance modelling approach, which uses input data such as daily rainfall, roof area, overflow losses, daily water demand and first flush. Ten different tank volumes are considered (1, 3, 5, 10, 15, 20, 30, 50, 75 and 100 m3). It is found that for a large roof area and tank size, the reliability of RWH systems for toilet and laundry use is high, in the range of 80–100%. However, the reliability for irrigation use is highly variable across all the locations. For combined use, Adelaide shows the smallest reliability (38–49%), while Hobart demonstrates the highest reliability (61–77%). Furthermore, economic analysis demonstrates that in a few cases, benefit–cost ratio values greater than one can be achieved for the RWH systems. The findings of this study will help the Australian Federal Government to enhance RWH policy, programs and subsidy levels considering climate-sensitive inputs in the respective cities.

Full Consideration

Few subjects have excited the imagination of archaeologists working in ancient complex societies as have monumentality and urban planning. Yet the two topics are rarely explicitly theorized in a sustained integrated investigation within a single study, despite the fact that monumental architecture is often considered a primary basis for identifying the presence of urban planning. This article makes the related methodological arguments that both phenomena benefit from a more full consideration of one another, and that the meaningful aspect of monumentality and urban symbology needs to be considered in conjunction with the formal aspect of monuments and urban layouts. These positions are then implemented in a study of the Syro-Anatolian city-state system that existed in the ancient Near East during the early first millennium bc. The capital cities of these polities were characterized by a program of monumentality that brought royalty, city walls, gates and monumental sculpture into an unmistakable constellation of associations. The consistency of this pattern of monumentality and urban form suggests that at least a degree of urban planning existed.
