Catchment Responses

Abstract The technical lifetime of urban water infrastructure has a duration where climate change has to be considered when alterations to the system are planned. Also, models for urban water management are reaching a very high complexity level with, for example, decentralized stormwater control measures being included. These systems have to be evaluated under as close-to-real conditions as possible. Long term statistics (LTS) modelling with observational data is the most close-to-real solution for present climate conditions, but for future climate conditions artificial rainfall time series from weather generators (WGs) have to be used. In this study, we ran LTS simulations with four different WG products for both present and future conditions on two different catchments. For the present conditions, all WG products result in realistic catchment responses when it comes to the number of full flowing pipes and the number and volume of combined sewer overflows (CSOs). For future conditions, the differences in the WGs representation of the expectations to climate change is evident. Nonetheless, all future results indicate that the catchments will have to handle more events that utilize the full capacity of the drainage systems. Generally, WG products are relevant to use in planning of future changes to sewer systems.

Urban Water Systems

<p>Diverse concepts have emerged in recent decades which (at least in their rhetoric) aim to instigate processes that make cities more resilient to climate change and support more sustainable urban development (Coaffee and Lee 2016; Hodson and Marvin 2017). With regards to urban water management, the Water-Sensitive City (WSC) is one such concept that promotes urban water planning to “protect, maintain and enhance the multiple benefits and services of the total urban water cycle that are highly valued by society” (Wong and Brown 2009, 674). The WSC, along with related integrated urban water management concepts have seen growing scholarly attention in recent years (see e.g. Fletcher et al. 2015). The emergence of such concepts reflects the growing demand for more sophisticated and integrated understanding and management of urban water systems. Such an ambitious model represents a broadening of the competencies and responsibilities of practitioners involved in water management and improved coordination with other urban sectors. Thus, such changes (must) typically coincide with changes amongst actors engaged directly or indirectly in water management, along with the prevailing institutional arrangements that govern their activities.</p> <p>Yet very little is known about processes of institutionalisation of such concepts within socio-technical regimes such as those that characterise urban water systems (Fuenfschilling and Truffer 2014). This paper aims to map processes of institutionalisation of concepts associated with the Water-Sensitive City amongst practitioners working in urban water management related fields in the Free and Hanseatic City of Hamburg. The research explores changes in the institutional arrangements between 1990 and 2020.</p> <p><strong>References</strong></p> <p>Coaffee, J., and P.
