The potential impact of climate change on areas of strategic importance for water resources remains a concern. Here, river flow projections for the River Medway, above Teston in southeast England are presented, which is just such an area of strategic importance. The river flow projections use climate inputs from the Hadley Centre Regional Climate Model (HadRM3) for the time period 1960–2080 (a subset of the early release UKCP09 projections). River flow predictions are calculated using CATCHMOD, the main river flow prediction tool of the Environment Agency (EA) of England and Wales. In order to use this tool in the best way for climate change predictions, model setup and performance are analysed using sensitivity and uncertainty analysis. The model's representation of hydrological processes is discussed and the direct percolation and first linear storage constant parameters are found to strongly affect model results in a complex way, with the former more important for low flows and the latter for high flows. The uncertainty in predictions resulting from the hydrological model parameters is demonstrated and the projections of river flow under future climate are analysed. A clear climate change impact signal is evident in the results with a persistent lowering of mean daily river flows for all months and for all projection time slices. Results indicate that a projection of lower flows under future climate is valid even taking into account the uncertainties considered in this modelling chain exercise. The model parameter uncertainty becomes more significant under future climate as the river flows become lower. This has significant implications for those making policy decisions based on such modelling results. Copyright © 2010 John Wiley & Sons, Ltd.

Roman Catholic separate schools’ denominational right to receive public funding is a contentious issue in Ontario’s educational system. Ontario’s publicly funded denominational schools historically served a purpose at Confederation; however, in light of Ontario’s evolving demographics, publicly funding denominational schools today may no longer serve the needs of Ontario. The research problem in this study is expressed through growing problems reconciling Roman Catholic schools with diversity and current public views. Additionally, recent tensions, public views, and political consensus suggest it is time to revisit the existing policy. In order to understand both the history of denominational schools and the present context, this study conducted II policy analyses as its research design by completing 2 policy cycles. The first policy cycle determined that based upon Upper and Lower Canada’s pre-Confederation diversity, extending public funding to denominational schools at Confederation was an effective way of protecting minority rights; however, the analysis in the second policy cycle; which examined how equitable and inclusive denominational schools are today, concluded that the denominational school system no longer serves the diversity and equity needs of contemporary Ontario. Building on these findings, this study then explored two viable alternative educational arrangements for Ontario’s future educational system: publicly funding all faith-based schools, or publicly financing a one-school-system. To address the diversity issue in Ontario, transitioning toward publicly funding a one-school-system is found to be the most viable option.
