“…This suggests that current knowledge of uncertainties arising from the standard modelling chain are likely to be significant for future design flood assessment and as a result we suggest that this supports the need to incorporate CM simulations in future design flood estimates. Probabilistic approaches need to be developed [44] to cascade these uncertainties into flood risk mapping in order to assess the influence these uncertainties have on future flood exposure.…”

“…Probabilistic approaches allow the uncertainty of climate models outputs to be characterized and sensitivity and performance of impact models evaluated based on these uncertainties. However, as reported by [44], these uncertainties can range widely, related to divergent GCMs outputs with large biases in simulation, especially precipitation, resulting in little concluding information for impact studies.…”

Floods are the most common and widely distributed natural risk, causing over £1 billion of damage per year in the UK as a result of recent events. Climatic projections predict an increase in flood risk; it becomes urgent to assess climate change impact on extreme flows, and evaluate uncertainties related to these projections. This paper aims to assess the changes in extreme runoff for the 1:100 year return period across Great Britain as a result of climate change using the Future Flows Hydrology database. The Generalised Extreme Value (GEV) and Generalised Pareto (GP) models are automatically fitted for 11-member ensemble flow series available for the baseline and the 2080s. The analysis evaluates the uncertainty related to the Extreme Value (EV) and climate model parameters. Results suggest that GP and GEV give similar runoff estimates and uncertainties. From the baseline to the 2080s, increasing estimate and uncertainties is evident in east England. With the GEV the uncertainty attributed to the climate model parameters is greater than for the GP (around 60% and 40% of the total uncertainty, respectively). This shows that when fitting both EV models, the uncertainty related to their parameters has to be accounted for to assess extreme runoffs.

“…According to IPCC (2007a), climate change can result in increased temperature, widespread ice and snow melting, rising sea level, widespread changes in precipitation and evaporation patterns, and increased frequency and magnitude of extreme weather events such as flood, droughts, and heat waves (IPCC, 2007a,b;USGS, 2007;Gurdak et al, 2009;Ludwig et al, 2014). These changes can substantially affect water resources management practices.…”

Climate change can result in significant impacts on regional and global surface water and groundwater resources. Using groundwater as a complimentary source of water has provided an effective means to satisfy the ever-increasing water demands and deal with surface water shortages problems due to robust capability of groundwater in responding to climate change. Conjunctive use of surface water and groundwater is crucial for integrated water resources management. It is helpful to reduce vulnerabilities of water supply systems and mitigate the water supply stress in responding to climate change. Some critical challenges and perspectives are discussed to help decision/policy makers develop more effective management and adaptation strategies for conjunctive water resources use in facing climate change under complex uncertainties.

“…However, this also fosters innovative governance arrangements and practices to build adaptive capacity to climate change impacts. Despite the main focus of IWRM is on current and historic issues compared to the long-term focus of adaptation (Ludwig et al 2014), they both (IWRM and adaptation) share the same goal of promoting sustainable development and both of them require some identical key elements (e.g. public participation, information sharing and disclosure, and concern for social justice) for their successful implementation (He 2013).…”

Climate change is one of the significant threats for the society. Water is the primary medium through which climate change influences the Earth's ecosystems and therefore people's livelihoods and well-being. Changes in hydrological cycle due to climate change can lead to diverse impacts and risks (Bates et al. 2008;Jiménez Cisneros et al. 2014). Jiménez Cisneros et al. (2014 synthesized water-related impacts on humans and Earth biomes. Renewable surface water and groundwater resources in most dry subtropical regions are projected to reduce due to climate change. The fraction of global population that will be affected by water scarcity and riverine floods is projected to increase with the level of warming in current century. Agriculture is directly related to water and therefore, food security will be potentially affected by climate change, including food production, transportation, process, access, use and price stability. Climate change and the associated impacts on water are expected to lead to increases in water-related diseases in many regions and especially in the low-income developing countries. In urban areas, climate change is projected to increase risks for people, assets, economies and ecosystems, including risks from heat stress, storms and extreme precipitation, inland and coastal flooding, landslides, air pollution, drought, water scarcity, sea level rise and storm surges. Rural areas are expected to experience major impacts on water availability and supply, food security, infrastructure and agricultural incomes, including shifts in the production areas of food and non-food crops around the world. Beside climatic drivers, other nonclimatic drivers such as current demographic trends, economic development and related land-use changes have direct impact on social and ecological systems and their processes. These drivers of change are closely linked to each other and pose complex management problems for land and water resources.In order to deal with these complex problems, water management issues should generally consider multiple decisional criteria and large numbers of possible alternatives, usually characterized by high uncertainty, complex interactions and conflicting interests of multiple stakeholders, but also of a multiplicity of compartments, such as river, land or coastal ecosystems or different economic sectors. Therefore, the traditional fragmented approach of management has to be replaced by more holistic system view approaches. Integrated water resources management (IWRM) is such an approach that has been widely accepted internationally as the way forward for efficient and equitable management of water and related resources.Climate change adaptation (CCA) is emerging in the policy agenda of policy-makers worldwide. In the field of water resources, one of the challenges for adaptation is to integrate and mainstream it into the paradigmatic IWRM concept. Integrating and mainstreaming adaptation with IWRM increases additional implementation burden on IWRM. However, this also fosters innovative...
