Climate change is expected to increase the frequency and intensity of extreme rainfall events, affecting rainfall intensity-duration-frequency (IDF) curve information used in the design, maintenance and operation of water infrastructure in Canada. Presented in this lecture are analyses of precipitation data from 567 Environment Canada hydro-meteorological stations using the IDF_CC tool. Results for the year 2100 based on the Canadian climate model and an ensemble of 22 GCMs were generated. A spatial interpolation method was used to produce Canadian precipitation maps for events of various return periods. Results based on the Canadian climate model indicate a reduction in extreme precipitation in central regions of Canada and increases in other regions. Relative to the ensemble approach, the Canadian climate model results (a) suggest more spatial variability in change of IDFs, and (b) the ensemble approach generated generally lower values than the Canadian climate model.
Dr. Slobodan Simonovic has extensive research, teaching and consulting experience in water resources systems engineering. He is teaching courses in water resources and civil engineering systems. He actively works for national and international professional organizations. Dr. Simonovic’s primary research interest focuses on the application of systems approach to management of complex water and environmental systems. Most of his work is related to the integration of risk, reliability, and uncertainty in hydrology and water resources management. He has received a number of awards for excellence in teaching, research and outreach. He has published over 450 professional publications and three major textbooks. He has been inducted to the Canadian Academy of Engineering in June of 2013.
