Review: A critical review of integrated urban water modelling - Urban drainage and beyond

Abstract: Modelling interactions in urban drainage, water supply and broader integrated urban water systems has been conceptually and logistically challenging as evidenced in a diverse body of literature, found to be confusing and intimidating to new researchers. This review consolidates thirty years of research (initially driven by interest in urban drainage modelling) and critically reflects upon integrated modelling in the scope of urban water systems. We propose a typology to classify integrated urban water system models at one of four 'degrees of integration' (followed by its exemplification). Key considerations (e.g. data issues, model structure, computational and integration-related aspects), common methodology for model development (through a systems approach), calibration/optimisation and uncertainty are discussed, placing importance on pragmatism and parsimony. Integrated urban water models should focus more on addressing interplay between social/economical and biophysical/technical issues, while its encompassing software should become more user-friendly. Possible future directions include exploring uncertainties and broader participatory modelling.

Technological advances and applications of geothermal energy pile foundations and their feasibility in Australia

Abstract: Geothermal energy pile foundations are an alternative energy source for heating and cooling needs. Utilising this source of energy has great potential due to the environmental, economic and social benefits. This paper looks at an extensive amount of literature on the technology behind the system including the overall process, primary considerations for each of the main components including latest developments as well as design implications such as the integration of ground energy systems into structural piles of buildings. Environmental considerations including performance-dependent parameters of the subsurface are described. Main parameters include thermal conductivity, thermal diffusivity, specific heat capacity and moisture content. Temperature and groundwater effects are also discussed and design considerations are provided. Mathematical models are available to aid in the design of these systems but there are various other issues and complex parameters that need to be considered qualitatively. Furthermore, the design of these systems is governed by various standards and government legislation. Case studies are presented to show the application of these systems in practise including assessments of system performance. Examples originate from countries such as Austria, Switzerland, Germany, UK, USA, Japan, Iran, Sweden and Norway. Benefits and limitations of implementing these systems are summarised and finally, the feasibility of geothermal energy pile foundations in Australia is explored. This paper found that these systems, although exhibiting some limitations and possible challenges, are a viable option in terms of an alternative energy source.

Framing water sensitive urban design as part of the urban form

Abstract: Spatial planning for green stormwater treatment technologies, known as Water Sensitive Urban Design (WSUD), is a wicked problem which can greatly benefit from the application of Planning Support Systems (PSS). Our review of currently existing WSUD-PSS shows that WSUD is approached from three perspectives: hydrological, urban planning and water governance. As a form of best (urban) planning practice, WSUD requires PSS that regard these technologies as an integral part of the urban form. We argue that suitability of location for WSUD has two sides: WSUD needs a place and a place needs WSUD. No framework or PSS exists that frames WSUD from both sides of suitability. We propose such a suitability framework, building on evidence from literature. Our review found no comprehensive tool or strategy incorporating all relevant factors for suitability analysis. Our proposed framework addresses this gap, and serves as the basis for rigorous WSUD-PSS.

Remodeling Grounded Theory

Abstract: In diesem Beitrag verdeutliche ich meine Besorgnis uber zahlreiche Umformungen der Grounded Theory (GT), die mit deren Rezeption durch Methodologien der qualitative Datenanalyse (QDA) einhergehen, und hieraus folgende Erosionen. Ich skizziere zunachst einige Beispiele hierfur, um danach die essentiellen Bestandteile der klassischen GT-Methodologie zusammenzufassen. Ich hoffe, dass dieser Beitrag meine Besorgnis uber die wachsende, aber meines Erachtens missverstandene Einvernahme von GT durch QDA-Methodologien veranschaulicht und zugleich als einfuhrender Leitfaden fur Novizen und Novizinnen dient, die daran interessiert sind, die grundlegenden Prinzipien der GT nachzuvollziehen.
