The Office of the Vice President for Research is pleased to host the next Water@Wayne seminar on Thursday, April 9, 2020 at 2:30 p.m. to 3:30 p.m. in the College of Engineering building, room 1520. The seminar is free and open to the public; registration is requested.
The Water@Wayne Seminar Series presents "A Systems Perspective on the Role of Green Infrastructure in Urban Watershed Hydrology and Biogeochemistry" with Dr. Anthony Parolari, assistant professor in the Department of Civil, Construction and Environmental Engineering at Marquette University.
Dr. Anthony Parolari completed his bachelor's and master's degrees in CEE at the University of Michigan, a PhD in CEE with a focus in ecohydrology at the Parsons Laboratory at MIT, and a postdoc at Duke University. He has 14 years of professional and research experience in hydrology and water resources engineering, including two years as a consultant in water infrastructure planning and management. Dr. Parolari’s research investigates the impact of climate on ecosystem processes, including plant productivity, soil biogeochemistry, surface water quality, and their responses to flood and drought. This research integrates experiments, data analytics, and computer modeling to improve basic understanding of complex environmental systems that can be leveraged to solve resource management challenges in natural, agricultural, and urban settings.
Urbanization degrades water quality by changing watershed hydrology and biogeochemistry. To mitigate negative water quality impacts of urbanization, cities have turned to green stormwater infrastructure (GSI) and low impact development (LID) practices to promote ecosystem services provided by natural hydrology and biogeochemistry regimes. For example, the Milwaukee Metropolitan Sewerage District (MMSD) has pledged to spend $1.3B on GSI toward their Vision 2035. Understanding and control of hydro-biogeochemical dynamics is therefore a critical foundation toward building sustainable urban systems. In this talk, I will discuss several research efforts in the Milwaukee region focused on monitoring, modeling, and real-time control of GSI for runoff and water quality management. During 2018 and 2019, we monitored soil hydrology and biogeochemistry across several urban green spaces, including a green roof, constructed wetland, detention pond, and urban farm. These measurements demonstrate strong coupling of hydrology and biogeochemistry in GSI at sub-daily to seasonal timescales, indicating that their water quality performance may be highly sensitive to variability in temperature and rainfall timing and intensity. Subsequently, we integrated these field experiments with process-based models to develop a systems-based reliability engineering framework for GSI analysis and design. The framework links hydro-climatic variability with GSI biogeochemistry to forecast a probabilistic characterization of water storage and effluent water quality. The models have been used to develop and evaluate novel design, management, and real-time control strategies to maintain the reliability of GSI stormwater and pollutant retention in variable environments. Together, this work demonstrates the complexity of GSI performance and points toward opportunities for urban water infrastructure adaptation to climate change.
