Urbanisation significantly impacts on water environments with increased runoff and the degradation of water quality. The management of quantity impacts are straight forward, but quality impacts are far more complex. Current approaches to safeguard water quality are largely ineffective and guided by entrenched misconceptions with a primary focus on 'end-of-pipe' solutions. The outcomes of a research study presented in the paper, which investigated relationships between water quality and six different land uses offer practical guidance in the planning of future urban developments. In terms of safeguarding water quality, high density residential development which results in a relatively smaller footprint would be the preferred option. The research study outcomes bring into question a number of fundamental concepts and misconceptions routinely accepted in stormwater quality management. The research findings confirmed the need to move beyond customary structural measures and identified the key role that urban planning can play in safeguarding urban water environments.Keywords: multivariate analysis, stormwater quality management, urban water quality, water quality impacts 3
This paper will present a project in progress on the use of computer graphics to enhance the communication of an emerging Urban Design concept -Transit Oriented Sustainable Urban Design (TOSUD). Two detailed virtual environments have been created relating to hypothetical TOSUD developments within an Australian and Chinese context. The process of development and resultant virtual environment will initially be discussed within the paper. Following this, the development of a unique computer interface, which facilitates community consultation within these virtual environments, will be presented. The case study and interface development provides a framework for the future application of such tools within the Built Environment disciplines.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
