Nexus water and climate change
With the clock counting down towards the November climate summit in Marrakech, Morocco, where parties to the climate treaty agreed in Paris will negotiate implementation, it’s clear that managing water resources will be a key aspect of any effective deal.

Characterizing Uncertainty of the Hydrologic Impacts of Climate Change - Online First - Springer
The high climate sensitivity of hydrologic systems, the importance of those systems to society, and the imprecise nature of future climate projections all motivate interest in characterizing uncertainty in the hydrologic impacts of climate change. We discuss recent research that exposes important sources of uncertainty that are commonly neglected by the water management community, especially, uncertainties associated with internal climate system variability, and hydrologic modeling. We also discuss research exposing several issues with widely used climate downscaling methods. We propose that progress can be made following parallel paths: first, by explicitly characterizing the uncertainties throughout the modeling process (rather than using an ad hoc “ensemble of opportunity”) and second, by reducing uncertainties through developing criteria for excluding poor methods/models, as well as with targeted research to improve modeling capabilities. We argue that such research to reveal, reduce, and represent uncertainties is essential to establish a defensible range of quantitative hydrologic storylines of climate change impacts.

An assessment of the possible impacts of climate change on snow and peak river flows across Britain - Springer
The focus of this paper is snowmelt and flood peaks in Britain. Most of Britain does not experience sustained periods of lying snow...However, snow is a major component of flow for some catchments, particularly in Scotland...individual snow events can affect flows anywhere in the country: snowmelt was a key factor in the major flooding that occurred across much of England in March 1947

Why do 100 year events happen so often?
The 1-hour, 1% AEP (100 year ARI) value has 1% chance of occurring at each of these points in a particular year, which means that there is a good chance (63% assuming full independence of points) of a 1-hour, 1% AEP (100 year ARI) event occurring somewhere in the general Melbourne area in each calendar year. (This is an approximation only as the assumption of independence of - zero correlation amongst - points varies with both the duration of rainfall under consideration and the type of rainfall-producing weather mechanisms which can operate in the area.)

UK drought and water scarcity project
Dr Len Shaffrey (from the Department of Meteorology and the National Centre for Atmospheric Science) is leading a four year project to improve forecasts of UK drought from months to years ahead. The project will receive £2 million of funding from across the UK Research Councils.

Water Climate Change Impacts Report Card | LWEC
This report card is for anyone who works with or has an interest in water in the UK. It looks at the effect of climate change on fresh water - including rainfall, floods and droughts. The report card is intended to help people understand the scale of possible change and to help inform decisions about the way that water is managed.

impacts of climate change on river flows in England using the UKCP09, Charlton and Arnell
This paper presents an assessment of the effects of climate change on river flow regimes in representative English catchments, using the UKCP09 climate projections. These comprise a set of 10,000 coherent climate scenarios, used here (i) to evaluate the distribution of potential changes in hydrological behaviour and (ii) to construct relationships between indicators of climate change and hydrological change. The study uses six catchments, and focuses on change in average flow, high flow (Q5) and low flow (Q95). There is a large range in hydrological change in each catchment between the plausible UKCP09 climate projections, with differences between catchments largely due to differences in catchment geology and baseline water balance. The range in change between the UKCP09 projections is in most catchments smaller than the range between changes with scenarios based on the CMIP3 ensemble of climate models (although the shape of the distribution of changes is different), and earlier UK scenarios produce changes that tend towards the lower (drier) end of the UKCP09 range. The difference between emissions scenarios is small compared to the range across the 10,000 scenarios. Changes in high flows are largely driven by changes in winter precipitation, whilst changes in low flows are determined by changes in summer precipitation and temperature.
