Assessment Of Climatic Vulnerability In The Upper Thames River Basin, Leanna King, Tarana Solaiman, Slobodan P. Simonovic

Water Resources Research Report

This study provides an assessment of possible future climate conditions for the Upper Thames River Basin.

City Of London: Vulnerability Of Infrastructure To Climate Change. Background Report #2: Hydraulic Modeling And Floodplain Mapping, Dragan Sredojevic, Slobodan P. Simonovic

Water Resources Research Report

The main objective of the research project currently under way is to provide an engineering assessment of the vulnerability of London’s public infrastructure under projected rates of climate change with special emphasis on flooding. An original systematic procedure is used to gather and examine available data in order to develop an understanding of the relevant climatic effects and their interaction with municipal infrastructure. Assessment of climate change impacts on municipal infrastructure requires floodplain maps and inundation that will correspond to examined climate change scenarios. This report presents the results of hydraulic analyses used in floodplain mapping under changing climate.

Combined, …

City Of London: Vulnerability Of Infrastructure To Climate Change, Hyung-Il Eum, Slobodan P. Simonovic

Water Resources Research Report

The climate is changing and these changes may induce severe impacts on both, global and local scales. The Public Infrastructure Engineering Vulnerability Committee (PIEVC) established by Engineers Canada conducted an assessment of the vulnerability of Canadian Public Infrastructure to changing climatic conditions. The major conclusion of the assessment is that water resources infrastructure failures due to the climate change will be common across Canada. As a follow up, the City of London took an initiative to evaluate the impacts of climate change on its municipal infrastructure. An original systematic procedure is used to gather and examine available data in order …

Updated Rainfall Intensity Duration Frequency Curves For The City Of London Under The Changing Climate, Slobodan P. Simonovic, Angela Peck

Water Resources Research Report

The main focus of this study is the update of rainfall IDF curves for the City of London under the conditions of changed climate. Predicted future climate change impacts for Southwestern Ontario include higher temperatures and increases in precipitation, leading to an intensification of the hydrologic cycle. One of the expected consequences of change is an increase in the magnitude and frequency of extreme events (e.g. high intensity rainfall, flash flooding, severe droughts, etc.). Changes in extreme events are of particular importance for the design, operation and maintenance of municipal water management infrastructure. Management of municipal water infrastructure (sewers, storm …

Energy Sector For The Integrated System Dynamics Model For Analyzing Behaviour Of The Social-Economic-Climatic Model, Evan G. R. Davies, Slobodan P. Simonovic

Water Resources Research Report

The system dynamics-based energy sector described here adds a representation of energy supply and demand dynamics, and their associated carbon emissions, to a larger society-biosphere-climate model previously described in Davies and Simonovic (2008). The inclusion of an energy sector expands the earlier model considerably, and provides new avenues for its application to policy development.

Five interconnected components constitute the full energy sector: demand, resources, economics, production, and emissions. The energy demand component calculates changes over time in heatenergy and electric-energy demand as a result of economic activity, price-induced efficiency measures, and technological change. Energy resources models changes in the amounts …

Integrated Reservoir Management System For Adaptation To Climate Change Impacts In The Upper Thames River Basin, Hyung-Il Eum, Vasan Arunachalam, Slobodan P. Simonovic

Water Resources Research Report

Climate change is one of the more pressing issues that attract the attention of scientists and policy makers. Many scientists are developing necessary methodologies to better understand the impacts of climate change, and support the development of appropriate adaptation measures. Literature on the application of adaptation measures to changing climatic conditions is very limited and the need for more work is evident on the development of adaptation strategies for mitigating negative impacts of climate change in water resources management practice.

This study presents an integrated reservoir management system for the Upper Thames River basin that includes: (1) a Weather Generator …

A Fuzzy Set Theory Based Methodology For Analysis Of Uncertainties In Stage-Discharge Measurements And Rating Curve, Rajesh R. Shrestha, Slobodan P. Simonovic

Water Resources Research Report

River stage and discharge records are essential for hydrological and hydraulic analyses. While stage is measured directly, discharge value is calculated from measurements of flow velocity, depth and channel cross-section dimensions. The measurements are affected by random and systematic measurement errors and other inaccuracies, such as approximation of velocity distribution and channel geometry with a finite number of measurements. Such errors lead to the uncertainty in both, the stage and the discharge values, which propagates into the rating curve established from the measurements. The relationship between stage and discharge is not strictly single valued, but takes a looped form due …
