Speech Title: Monte Carlo Enhancement Using Simulation Decomposition: Visual Analytics in Environmental Decision-Making


Abstract: Environmental and energy engineering problems frequently require the need for decision-making in situations containing considerable degrees of uncertainty. Monte Carlo simulation methods have been used in a wide array of environmental planning settings to incorporate these uncertain features. Simulation-generated outputs are commonly displayed as probability distributions. Recently simulation decomposition (SIMDEC) has enhanced the visualization of the cause-effect relationships of multi-variable combinations of inputs on the corresponding simulated outputs. SIMDEC is a visual analytics approach that partitions sub-distributions of the Monte Carlo outputs by pre-classifying selected input variables into states, grouping combinations of these states into scenarios, and then collecting simulated outputs attributable to each multi-variable input scenario. Since it is a straightforward task to visually project the contribution of the subdivided scenarios onto the overall output, SIMDEC can illuminate previously unidentified connections between the multi-variable combinations of inputs on the outputs. SIMDEC is readily generalizable to any Monte Carlo method with negligible additional computational overhead and can, therefore, be readily extended into most environmental analyses that use simulation models. This presentation provides a background to the overall SIMDEC methodology, highlights various areas for advancement, and demonstrates the relative efficacy of SIMDEC for supporting decision-making in environmental/energy engineering by highlighting a number of case applications.


Brief biography: Julian Scott Yeomans is a Professor of Operations Management and Information Systems at York University’s Schulich School of Business in Toronto, Canada. He holds degrees in management science/information systems, environmental engineering, and statistics. He generally teaches courses on VBA programming, business analytics, and spreadsheet-based decision support systems. He has published 5 books (including 3 on incorporating climate change uncertainties into environmental assessments) and over 125 peer-reviewed, academic journal articles on a wide spectrum of topics. His most recent research has focused on the applications of different combinations of simulation-optimization, machine learning, visual analytics, population-based metaheuristics, and modelling-to-generate-alternatives. Current application areas of these methods include environmental informatics, waste management, empirical finance, and the optimal osmotic dehydration of fruits, vegetables, and fungi.

University of Alberta, Canada


Speech Title: Eco-hydraulics for Sustainable Hydropower


Abstract: In this talk, I will discuss recent research development on eco-hydraulics related to sustainable hydropower. I will first talk about our research work on assessing fish entrainment risk related to dam intake operations for run-of-the river dams as well as deep dams. The effect of temperature stratifications on fish entrainment will be discussed. This will be followed by our current research on predicting and mitigating the generation of supersaturated total dissolved gases caused by dam spill events. The upstream migration of fish through vertical slot fishways and fishway hydraulics will then be discussed. Our recent study on the hydraulics and design of nature-like fishways using rock ramps will then be summarized.

Speech Title: Modeling of urban agglomeration ecosystem management under uncertainty


Abstract: Urban agglomeration, comprising a group of cities in a specific geographical area, is a densely populated region with close economic connections. Urban agglomeration is often associated with high-density population and various interactions among multiple economic sectors, which can correspondingly bring more complexities to urban agglomeration management. System analysis techniques are effective tools that could help examine economic, environmental and ecological impacts of alternative pollution-control and resources-conservation actions, and thus aid planners or decision-makers in formulating cost-effective management policies. This research aims to develop assessment and optimization methods for reflecting a variety of uncertain, dynamic and nonlinear factors as well as to apply them to the Pear River Delta urban agglomeration that plays an important role in China’s economic development. Results are helpful for generating synergetic management strategies for urban agglomeration, which can effectively balance conflictive objectives among economic growth, resources conservation, and eco-environmental protection.

Speech Title: Hydropower change of the water tower of Asia in 21st century: A case of the Lancang River hydropower base, upper Mekong


Abstract: This study evaluates the future change in hydropower potential and sustainability of the Tibetan Plateau (TP) in 21st century under climate change, using the Lancang River hydropower base (LRHB) in the upper Mekong basin (UMB) as a case study. Future climate projections simulated by five different global climate models (GCMs) individually and the variable infiltration capacity (VIC) distributed hydrological model coupled with a reservoir model are used to project the future hydropower outputs. Results present a generally ideal prospect for hydropower development in the UMB, as most GCMs illustrate overall increasing hydropower outputs of the plants along with the increasing reservoir inflow. The sustainability of the hydropower is also improved in most GCMs, with generally higher reliability and lower vulnerability; however, due to the large impact of increased climate variability, some GCMs show poorer sustainability for the hydropower plants in the future scenarios, even though its overall hydropower outputs are increased. Therefore, the negative influence of the increased variability of some passive GCM projections still indicates the risks for hydropower development in the TP and thus requires consideration. This study is expected to provide reference for further hydropower planning and development over the TP under climate change. Keywords: Hydropower potential; Hydropower sustainability; Climate change; Global climate model (GCM); Tibetan plateau; Upper Mekong basin
