This project proposes a computational framework to efficiently simulate the flood-infrastructure interaction mechanism, assess the impact and risk of flood on the infrastructure in the southern Lake Michigan region and provide recommendations on the selection of rational infrastructure types suitable for the flooding area. The goal of the proposed research is to mitigate potential losses, improve the current post disaster reconstruction strategy and therefore enhance the flood resilience of the infrastructure and coastal communities in the Great Lake region. Key outcomes include an extensive literature review on the flood hazard data and infrastructure damage data in the southern Lake Michigan region, and a computational framework that integrates the fluid-structure interaction model and flood risk assessment model.

Little progress has been made toward reducing fatal drowning incidents in the United States (U.S.) in the last 20 years. Recent data from the Great Lakes indicate the COVID-19 pandemic resulted in excess drownings during summer 2020. Chicago has 26 miles of Lake Michigan shoreline and 24 free, public beaches that are punctuated with piers and jetties. The resultant structural currents pose unique risks to patrons who often access the lake outside of the official summer season and in the summer season after lifeguards go off duty at 7 p.m. There is an urgent need for effective education programs to raise awareness about recreation safety in Lake Michigan, the deadliest of the Great Lakes, and to increase water competence in diverse communities that have historically been excluded from swimming. The community-engaged injury prevention and water safety experts in Chicago are uniquely situated to respond.

Objective 1: To assess the impact of Chicago Park District’s Community Water Safety Trainings on program participant knowledge and skills, community-level knowledge, and distressed swimmer events and drownings.

Objective 2: To implement, pilot, and evaluate the Swim to Survive Program enhanced with Great Lakes safety education in Evanston, IL and adapt the program for implementation in Chicago communities.

Our overall goal is to is to is to gain insight into the basic biology of Craspedacusta in order to better predict its ecological impact in response to climate change. In particular, we are interested in the following questions:

1. What are the environmental cues for Craspedacusta jellyfish blooms and can these cues predict when and where Craspedacusta blooms will occur in southern Lake Michigan?
2. Can these conditions be replicated in a laboratory environment to induce jellyfish formation?
3. Are the genetic mechanisms that control jellyfish blooms in Craspedacusta similar to that of their marine relatives, and thus likely to have a parallel response to climate change?

To address these questions we have three primary objectives:

1. Determine environmental parameters required for jellyfish blooms through field work and citizen science approaches;
2. With the involvement of undergraduates we will design and conduct laboratory experiments utilizing environmental parameters and zooplankton composition data from objective 1, with the intention of culturing Craspedacusta medusae to their reproductive stage.
3. Conduct transcriptional analyses to document differential gene expression in the different life cycle stages to determine the genetic cues for life cycle transitions. 

We have a fourth objective to improve scientific literacy on invasive aquatic species though developing educational modules with live Craspedacusta jellyfish for the public, K-12 classrooms, focusing on underserved communities.

• Develop an optimal methodology for largemouth bass (LMB) muscle hydrolysis using digestive enzymes representing LMB digestive tract
• Evaluate the effect of LMB muscle protein hydrolysate used as first feed on the growth and survival of LMB larvae
• Provide feed/additive manufacturing industry with knowledge and tools required for production of high-quality, cost effective, and well-digested dietary muscle hydrolysate as a source of protein in larval fish feeds

High lake levels have reduced beach sizes across Chicago, but we have little understanding of how much was passive inundation versus sediment remobilization. Ongoing collaborative efforts with the Chicago Park District and the Illinois Coastal Management Program are focused on observations of process-landform dynamics using camera arrays at select beaches and integrating UAS-based imagery, topographic information, wave data, and camera footage. However, while efforts are underway to understand the subaerial dynamics here (e.g., shoreline behaviors), little is known about littoral dynamics and sand transport across the highly fragmented urban nearshore environment, where prior studies have inferred a complex lakefloor geology that includes outcropping Silurian bedrock reefs, heavily scoured and dissected glacial clay tills, and thin, discontinuous sand veneers. We wish to capture the geologic configuration of the nearshore at the surface and map the shallow subsurface architecture as a means of quantifying sand volumes and relating them to the broader geologic template and the urban infrastructure with its influence on nearshore hydrodynamics.

Aquaponics food production systems produce more food on less land, using less water than conventional food production systems. Further, they can be located near population centers, diminishing the carbon footprint of long-distance transportation of foods. Fresh food supplies in urban cities in the US takes advantage of the developing trends among consumers seeking sustainable, fresh, locally grown food supplies. Marine aquaponic systems are capable of producing fresh seafood and plant crops with high market value and strong consumer demand, but few species combinations have been developed well enough for practical applications. In this project, we propose continuing our ongoing efforts to explore marine aquaponics and provide operational guidelines for successful production.

Objective 1 – Complete our developing list of salt-tolerant plant species with a focus on seed availability, recommendations for germination, growth rates, and chemical composition data;
Objective 2 – Evaluate the long-term sustainability of a shrimp/plant marine aquaponic system, and evaluate salinity tolerance of 3-6 halophytic plant crop in marine aquaponics systems; and,
Objective 3 – Determine characteristics of the Asian markets in Chicago for products from marine aquaponic FPS and estimate total poundage of market demand.
