| Abstract

Water quality modeling is paramount for unraveling the intricacies of water systems, predicting the ramifications of human activities, and refining management practices and policies. Through scenario simulations, stakeholders can forecast outcomes, evaluate regulatory efficacy, and devise effective strategies for pollution mitigation and habitat restoration. Moreover, water quality modeling aids in assessing the impacts of climate change, bolstering environmental planning efforts, and facilitating evidence-based decision-making via comprehensive datasets. Ultimately, it serves as a cornerstone in safeguarding water resources for present and future generations. This presentation will describe a case study of Lake St. Charles in Quebec, Canada, an exemplar of a rural-urban lake facing challenges from urbanization and wastewater. Through meticulous modeling, seasonal variations and environmental factors influencing phytoplankton cycles were illuminated, informing proactive water management strategies. This presentation will also showcase how the integration of cutting-edge modeling techniques with on-the-ground data collection can pave the way for transformative advancements in water resource management, ensuring the long-term health and vitality of our waterways

| Speaker Bio

Seyed Abbas Hosseini Sadabadi is currently a senior postdoctoral researcher at Institut National de la Recherche Scientifique (INRS), Quebec, Canada, working on water quality modeling in St. Charles Lake, a drinking water reservoir in Quebec. He received his Ph.D. in Environmental and infrastructure Engineering in 2017 from the Politecnico di Milano (PoliMi), Milan, Italy. His work at PoliMi mainly was to introduce a novel conceptual framework to define and study the Lagrangian and Eulerian descriptors of bed-load sediment transport in rivers. Seyed Abbas also wrote a book chapter in GeoPlanet: Earth and Planetary Sciences, Springer, entitled, “An analysis of entrainment and deposition rate fluctuations in weak bed-load transport”. He then joined AmirKabir University of Technology (Tehran Polytechnic), Tehran, Iran in 2018 as a postdoctoral research fellow and has been involved in the analysis of 2019 floods in Iran, taking into account the management of the risks through a multi-hazard approach and to guarantee the schematic strategy and operation. He also investigated the Einstein's equation for bed-load sediment transport and modified a new version of this equation with better predictability of bed-load fluxes. His current project at INRS aims to conduct a comprehensive 3D numerical simulation to assess current water quality conditions in Lake St. Charles while also projecting future scenarios. The simulation will provide valuable insights into the lake's water quality dynamics, enabling better management and conservation efforts
