“…Interventions which perform well within standard conditions may fail to provide protection to high‐magnitude events (Butler et al, ). Managing extreme events is of particular relevance in the field of surface water management due to the future probability of high‐magnitude events increasing in response to growing cities and a changing climate (Chocat et al, ; Howard et al, ; IPCC, ).…”

“…In particular, studies and legislation emphasise application of innovative management interventions, for example, green infrastructure, to manage consequences of events (House of Commons, 2016). Addressing flooding using effective management interventions is of contemporary importance given changes to climate, land use, and demographics that are likely to exacerbate future flood hazards (Barbosa, Fernandes, & David, 2012;Chocat et al, 2007;Goonetilleke, Thomas, Ginn, & Gilbert, 2005;Howard et al, 2010;IPCC, 2014).…”

Despite significant consequences caused by recent events, surface water flooding has historically been of lower priority relative to fluvial and coastal risks in UK flood management. Legislation and research proposes a variety of innovative interventions to address this; however, widespread application of these remains a challenge due to a number of institutional, economic, and technical barriers. This research applies a framework capable of fast and high‐resolution assessment of intervention cost‐effectiveness as an opportunity to improve available evidence and encourage uptake of interventions through analysing permutations of type, scale, and distribution in urban catchments. Fast assessment of many scenarios is achieved using a cellular automata flood model and a simplified representation of interventions. Conventional and green strategies are examined across a range of design standard and high‐magnitude rainfall events in an urban catchment. Results indicate high‐volume rainwater capture interventions demonstrate a significant reduction in estimated annual damage costs, and localised surface water drainage interventions exhibit high cost‐effectiveness for damage reduction. Analysis of performance across a wide range of return periods enhances available evidence for option comparison decision support and provides a basis for future resilience assessment of interventions.

“…To provide more context for these characteristics, examples from the papers are provided below. For example, some authors argue that resilient systems are those capable of adapting to a wide range of potential climate scenarios (Howard et al, 2010). Interconnectivity can relate to connections across scales or sectors, or having high levels of integration across different levels of governance.…”

Resilience is increasingly applied the context of water systems, and water governance more broadly, in response to climate change impacts, hydrologic variability and uncertainty associated with various dimensions of global environmental change. However, the meanings, applications and implications of resilience as it relates to water governance are still poorly understood. Drawing on a systematic scoping review of the peer‐reviewed academic literature, this paper addresses the questions: how is resilience framed in relation to water systems and water governance, how are diverse resilience framings (re)shaping ideas and trends in water management, and what are the associated implications? The analysis found that the resilience‐informed water governance literature remains fragmented and predominantly centered on conventional approaches and framings of water planning, with a predominant focus on engineering resilience in water supply infrastructure. A recently emerging engagement with resilience in the water governance literature, however, draws on more diverse framings and theories and calls for a shift towards more integrative and ecologically‐centered thinking in water governance. Despite this, significant empirical and conceptual gaps remain, particularly around the integration of the various subsectors of water governance and, more importantly, around the institutional and governance dimensions of building water resilience.

“…The associated build-up of greenhouse gases in the lower atmosphere and acidification of the oceans is changing the hitherto relatively stable Earth system within which society has flourished. Temperatures are rising regionally and globally, and will continue to do so, but the regional effect of this change on precipitation is less understood and extremely varied from region to region (Howard et al, 2010).…”

“…Adaptation strategies must be developed that are as robust and 'no-regrets' as possible, even given a large range of plausible futures (Dessai et al, 2009). Effective management, aided by better tools to make beneficial adaptation decisions, is regarded as more important to increasing water supply resilience than the technologies involved (Howard et al, 2010). However, despite vast swathes of literature on the clear need for adaptation in the face of modelled climatic changes over the 21 st Century, the extent to which it has been meaningfully carried out in developed nations is surprisingly minimal, with large regional and sectoral variances (Ford et al, 2011).…”

The use of probabilistic weather generator information for climate change adaptation in the UK water sector

Adapting to climate change in the water sector requires abandoning two crucial assumptions. First, that the climate represented in the instrumental record is representative of the future. Instead, future water resource planning cannot be based on old measurements (or sequences derived from attaching change factors to instrumental data) and it should be recognized that stationarity is no longer viable, and, second, that climate modelling can be expected to give precise and certain predictions of the future. Instead, probabilistic projections of the future that take into account the full range of uncertainty should form the basis of robust climate change adaptation plans.As a response to the first assumption, it is suggested that stochastic weather generators represent a particularly useful approach to understanding the impacts of future climate change on water resources at a catchment scale, particularly given the recent release of 'science-hidden' tools such as the UKCP09 weather generator. With regards to the second assumption, it is suggested that modelling activity should identify the range of plausible futures to develop probabilities of risk, using those robust decision-making techniques which can gauge the performance of potential adaptation strategies.The best practice for delivering a replicable and practical hydroclimatological impact assessment for UK water resources at a catchment scale is identified, and an hypothetical example is outlined. It is suggested that although augmenting the resilience of water resources to climate change on a catchment scale is dependent on using the correct modelling tools, the robustness of the method with which that information is used to make adaptation decisions is equally as important.
