Book Description
Rapidly changing climatic conditions across the globe are believed to have an impact on key climate variables and the hydrologic cycle. Changes in magnitude and frequency of peak flow patterns have been noted in rivers worldwide. The associated risk is projected to increase many folds during the 21 st century. Therefore, it is necessary to quantify these impacts for effective water resource planning and management in future. Methodology chosen to do so should be able to capture variations in climate variables at fine temporal, spatial and distributional scales. Also, it should be able to cover uncertainties associated with future climatic, socio-economic and physiographic projections. In this study, a methodology for making future flow projections has been presented and applied to the Grand River basin, Ontario, Canada. Results indicate consistent decreases in peak flows across the catchment for all the scenarios considered in the analysis.

Book Description
Climate change is one of the most significant global environmental drivers threatening the quality and quantity of future water resources. Global temperature increases will have significant effects on the hydrologic regime of northern regions due to changes in snowfall and snowmelt. Considerable research has been conducted in western Canada to rigorously quantify snowmelt-driven streamflow processes, however, less focus has been directed towards understanding these processes in eastern Canada and Ontario. In the southern Ontario Grand River Watershed (GRW), snowmelt contributions to streamflow (freshet) make up a significant portion of the annual water yield, and the period of snowmelt is also of key concern for flood mitigation. This thesis aims to quantify historical and projected changes to timing and streamflow during freshet in the Nith River, an unregulated tributary of the Grand River. Climate data (temperature, rainfall, snowfall, and snow proportion) from observations and future scenarios were analyzed to quantify the contributions of climate conditions surrounding the timing and volume of the freshet. The annual timing of snowmelt-driven streamflow was quantified using centre time (CT), and streamflow volumes were quantified by various percentiles of streamflow (Qn) during four periods of the water year (October-December, January-February, March-April, and May-September). Historical trends in streamflow and climate data were examined using hydrometric data (1914-2016) of a stream gauge from the Water Survey of Canada, and climate data (1950-2016) from Environment and Climate Change Canada at two stations. Projected climate data were from an ensemble of models used in the Intergovernmental Panel on Climate Change's Fourth Assessment Report (AR4). A total of nine distinct models ran two scenarios from AR4 for the 2050s; moderate (B1) and high (A1B). These time-slice projections were then used to force the hydrologic model GAWSER to simulate future streamflow data. The results show that CT in the Nith River has advanced by 17 days, on average, from 1914 to 2016 (P=0.036), and the advance is projected to continue as a function of future emissions scenario (approximately 12 days for scenario B1, and 17 days for A1B). Historical CT was weakly negatively correlated with temperature (-0.51, P

Book Description
Hydro-climatic change is no longer an abstract or theoretical concept if you have been directly affected by the increase in the duration and intensity of extreme weather. In this new RMB manifesto, two of Canada's most respected water experts explain what is happening to the hydrological cycle by way of the very personal impacts that disastrous flooding had on them, their colleagues, neighbours, friends and family. Detailing events as the rain started to fall and the water began to rise, Kerry Freek provides an extraordinary narrative of the flooding that took place in downtown Toronto in July of 2013, while Robert Sandford provides a minute by minute account of what happened in June of 2013 throughout southern Alberta. The exceptional flooding detailed in this startling new book is nothing compared to what the atmosphere is capable of delivering in the future. Extreme weather events are making it clear that it's time to take climate change even more seriously than previously thought and that citizens, corporations and governments around the world must prepare for what many observers are now calling "the new normal" when it comes to major meteorological events.

Book Description
Hydroclimatic extremes, such as floods and droughts, affect aspects of our lives and the environment including energy, hydropower, agriculture, transportation, urban life, and human health and safety. Climate studies indicate that the risk of increased flooding and/or more severe droughts will be higher in the future than today, causing increased fatalities, environmental degradation, and economic losses. Using a suite of innovative approaches this book quantifies the changes in projected hydroclimatic extremes and illustrates their impacts in several locations in North America, Asia, and Europe.

Book Description
Flood risk management is presented in this book as a framework for identifying, assessing and prioritizing climate-related risks and developing appropriate adaptation responses. Rigorous assessment is employed to determine the available probabilistic and fuzzy set-based analytic tools, when each is appropriate and how to apply them to practical problems. Academic researchers in the fields of hydrology, climate change, environmental science and policy and risk assessment, and professionals and policy-makers working in hazard mitigation, water resources engineering and environmental economics, will find this an invaluable resource. This volume is the fourth in a collection of four books on flood disaster management theory and practice within the context of anthropogenic climate change. The others are: Floods in a Changing Climate: Extreme Precipitation by Ramesh Teegavarapu, Floods in a Changing Climate: Hydrologic Modeling by P. P. Mujumdar and D. Nagesh Kumar and Floods in a Changing Climate: Inundation Modelling by Giuliano Di Baldassarre.

Book Description
Negotiated over 60 years ago and ratified in 1964, the Columbia River Treaty (CRT or "the Treaty"), is often looked to as the standard for cross-jurisdictional water management. A crucial aspect of the Treaty is the governance of water flows to minimize downstream flooding. Climate change directly impacts the hydrology of the Columbia River, which has implications for activities such as power generation and flood control management. The Treaty needs to be modernized to incorporate the effects of climate change. Current discussions between Canada and the United States over the Treaty provide an opportunity to incorporate potential impacts of climate change on measures Canada could be asked to take to reduce downstream flooding. This study looks at the effects of climate change on flood risk within the Columbia River Basin and analyzes the costs and benefits associated with the operation of a provision in the current treaty known as 'Called Upon' flood control. This study then presents the information that may be helpful for the Canadian Entity to frame negotiation options given the potential impacts of climate change.
