The Comparison Of Gev, Log-Pearson Type 3 And Gumbel Distributions In The Upper Thames River Watershed Under Global Climate Models, Nick Millington, Samiran Das, Slobodan P. Simonovic

Water Resources Research Report

The increase in greenhouse gas emissions has had a severe impact on global temperature, and is affecting weather patterns worldwide. With this global climate change, precipitation levels are changing, and in many places are drastically increasing. The need to be able to accurately predict extreme precipitation events is imperative in designing for not only the safety of infrastructure, but also people’s lives. To predict these events, the use of historical data is necessary, along with statistical distributions that are used to fit the data.

In this study, historical data from the London International Airport station has been used, along with …

An Integrated System Dynamics Model For Analyzing Behaviour Of The Social-Energy-Economic-Climatic System: Model Description, Mohammad Khaled Akhtar, Slobodan P. Simonovic, Jacob Wibe, Jim Macgee, Jim Davies

Water Resources Research Report

The feedback based integrated assessment model ANEMI represents the society-biosphereclimate- economy-energy system of the earth and biosphere. The development of ANEMI model is done using the system dynamics simulation approach that (a) allows understanding and modeling of complex global change and (b) assists in the investigation of possible policy options for mitigating, and/or adopting to global changing conditions, within an integrated assessment modeling framework. This report presents ANEMI model and its nine individual sectors: climate, carbon cycle, land-use, population, food production, hydrologic cycle, water demand, water quality, and energy-economy. Two versions of the model are developed and presented in the …

An Integrated System Dynamics Model For Analyzing Behaviour Of The Social-Energy-Economic-Climatic System: User’S Manual, Mohammad Khaled Akhtar, Slobodan P. Simonovic, Jacob Wibe, Jim Macgee, Jim Davies

Water Resources Research Report

The User's Manual is planned to assist the user in (i) understanding the ANEMI model structure; and (ii) learning how to use the model for policy simulation. ANEMI model is a research product and is not developed as a commercial software. This manual contains a brief description of the main features of the Vensim system dynamics simulation software (Ventana, 2010), as well as integrated simulationoptimization procedure developed by incorporating MATLAB (MathWorks, 2007) functionalities with Vensim system dynamics simulation. With the help of Vensim and MATLAB software packages, the user can use, modify and/or run the ANEMI models provided with the …

Water Resources Decision Making Under Uncertainty, Dejan Vucetic, Slobodan P. Simonovic

Water Resources Research Report

Uncertainty is in part about variability in relation to the physical characteristics of water resources systems. But uncertainty is also about ambiguity (Simonovic, 2009). Both variability and ambiguity are associated with a lack of clarity because of the behaviour of all system components, a lack of data, a lack of detail, a lack of structure to consider water resources management problems, working and framing assumptions being used to consider the problems, known and unknown sources of bias, and ignorance about how much effort it is worth expending to clarify the management situation. Climate change, addressed in this research project (CFCAS, …

City Of London: Vulnerability Of Infrastructure To Climate Change Final Report, Angela Peck, Elisabeth Bowering, Slobodan P. Simonovic

Water Resources Research Report

The Earth's climate is changing and these changes are documented to have a serious impact on municipal infrastructure. Current infrastructure is designed and constructed based on standards and codes developed decades ago. These standards and codes include historic climate and design storms which are no longer representative of the current climate. With the changes in climate patterns, infrastructure may no longer have the capacity to handle new climate loads. Thus, a region must adapt its policies and procedures to consider climate change and mitigate risks to municipal infrastructure. Climate modeling suggests that the City of London can expect to experience …

Development Of Probability Based Intensity- Duration-Frequency Curves Under Climate Change, Tarana A. Solaiman, Slobodan P. Simonovic

Water Resources Research Report

Hydrologic design of storm sewers, culverts, retention/detention basins and other components of storm water management systems are typically performed based on specified design storms derived from the rainfall intensity-duration-frequency (IDF) estimates and an assumed temporal distribution of rainfall. Use of inappropriate data or design storms could lead to malfunctions of the infrastructure systems: over-estimation may result in costly over-design or under-estimation may be associated with risk and human safety. One of the expected hydroclimatic impacts of climate change for London is the increase in the magnitude and frequency of extreme rainfalls which can have serious impact on the design, operation …

Quantifying Uncertainties In The Modelled Estimates Of Extreme Precipitation Events At The Upper Thames River Basin, Tarana A. Solaiman, Slobodan P. Simonovic

Water Resources Research Report

Assessment of climate change impact on hydrology at watershed scale incorporates downscaling of global scale climatic variables into local scale hydrologic variables and computations of risk of hydrologic extremes in future for water resources planning and management. Atmosphere-Ocean General Circulation (AOGCM) models are designed to simulate time series of future climate responses accounting for enthropogenically induced green house gas emissions. The climatological inputs obtained from several AOGCMs suffer the limitations due to incomplete knowledge arising from the inherent physical, chemical processes and the parameterization of the model structure. This study explores the methods available for quantifying uncertainties from the AOGCM …

Assessment Of Global And Regional Reanalyses Data For Hydro- Climatic Impact Studies In The Upper Thames River Basin, Tarana A. Solaiman, Slobodan P. Simonovic

Water Resources Research Report

This study evaluates NCEP-NCAR reanalyses hydro-climatic data as an initial check for assessment of climate change studies and hydrologic modeling on the basin scale. Reanalysis data set for daily precipitation, and temperature from the National Centers for Environmental Prediction-National Center for Atmospheric Research (NCEP-NCAR) (a) global (NNGR) and (b) regional (NARR) reanalysis project are used as input into the semi-distributed hydrologic model (HEC-HMS) during the period of 1980-2005. First, the precipitation and temperature data are interpolated to selected stations to check for their trends and similarity in means and variances. Although NARR shows some over-estimated values, mainly in estimating temperature …
