Green Infrastructure and Flooding

Detroit Biodiversity Network's 6000 Woodward Bioswale and iBioswale

The mission of the Detroit Biodiversity Network (Biophiliacs) is to engage students in hands on projects that support and improve the sustainability of urban ecosystems on Wayne State University's campus and in surrounding Detroit communities. DBN grows native plants on the greenhouse atop Science Hall and plants them in numerous locations around campus. Two of their most recent installations have been two bioswales near the Integrative Bioscience Building. These bioswales include native plants and collect stormwater runoff from adjacent parking lots.

Green Infrastructure Flood Mitigation Analysis and Modeling

This study provides detailed information about an area in the City of Detroit that has had known flooding problems and a significant number of FEMA flood damage claims from 2000 and 2014.  The modeling and analysis performed is applicable for strategically locating green infrastructure and other alternative storm water treatment practices in this area.  The analysis also is applicable for assessing the effects of alternative storm water management practices on flooding.  Most importantly, the analysis process is documented to provide a tool with broad applicability for identification of appropriate flood mitigation actions generally.

Evaluating the Effects of Urban Tree Canopy Cover Changes on Stormwater Quality and Quantity within a Sub-watershed in the Rouge River Watershed

The main objective of this study is to evaluate the effects of tree canopy cover changes on stormwater quality and quantity in a watershed. This will be accomplished by analyzing the combined sewer flow measurements obtained from six (6) meters located within the city of Dearborn. It will involve separating runoff entering the sewer line from the combined sewer flow measurements obtained from the 6 (six) meters. In addition, surface runoff values obtained using the modified NRSC-SCS curve number method, which incorporates the term interception capacity will be compared with runoff measurements from the combined sewer flow during period of low and high tree canopy cover within the sub-watershed. Also, stormwater samples will be collected and analyzed for the contaminants of interest during periods of low and high tree canopy cover.  

Detroit Flooding Study

HUW researchers teamed up with Wayne State's Center for Urban Studies and University of Michigan researchers to better understand the prevalence of flooding in Detroit. This project looked at flooding prevalence across the city from 2012 to 2020 finding that nearly 43% of households surveyed reported household flooding. A journal article was recently published as well as a report outlining the issue of flooding across the city.

Mold Study

Funded by a One Health grant, HUW researchers and collaborators are working to better understand the impact of basement flooding on Detroiters as well as the potential causes. This pilot project aims to better understand the presence of mold in the basements of flooded homes and determine potential causes of flooding in people's homes.

Data Collection

Huron to Erie Drinking Water Monitoring Network

The Huron to Erie Drinking Water Monitoring Network was established in 2007 to provide early warning of chemical spills or contamination that may impact the source of drinking water along the Huron to Erie corridor. Healthy Urban Waters currently manages the data and website. Check out this video for more information about this initiative.

Lake St. Clair Lake and Marsh Water Quality Monitoring

Two sondes were installed in Lake St. Clair and Point Rose Marsh at Lake St. Clair Metropark. These sondes provide real-time water quality data which allows analysis.

Assessment and prediction of Infiltration/Inflow int the Urban sewer collection systems

Infiltration and Inflow (I/I) significantly increments the operation and maintenance costs and adversely affect the operation of both sewer transmission system and wastewater treatment plant. Moreover, I/I cause tremendous impacts on economy, environment, energy consumption, public health, safety and etc.

Our study objectives are to develop a standard method to separate and quantify the infiltration/inflow and build models to predict I/I during rainfall events (RDII). The primary goal is for the Metro Detroit Utilities and operators to implement the research findings and methods in any future I/I study at other sites within the city to direct and optimize their policies, management decisions, and maintenance plans.

VOC Plant Study

The study evaluates phytoscreening as a method of screening subsurface volatile organic compounds (VOCs) in urban neighborhoods in Detroit, MI. VOCs are a common chemical group often present in urban neighborhoods and require invasive and costly sampling techniques. In addition, VOCs present a direct human health exposure route through vapor intrusion (VI). Despite the critical threat of this chemical pathway, evaluating exposure routes and proposing remediation strategies remains a complex and often expensive challenge. New methods are required to assess sites of known subsurface VOC contamination. The project evaluates the role of vegetation and soil gas flux on VOC soil gas movement. WSU, with the Michigan Department of Environment, Great Lakes, and Enegary (EGLE), is actively evaluating VOCs at two brownfield locations in Detroit. In addition, example plants and flux chambers were used in the greenhouses at Wayne State University to evaluate changes to VOC concentration both in the soil, uptake of the plant, and movement into the flux chamber. Field work and sampling are occurring this summer at the field locations and the greenhouses at WSU.

Lake St. Clair Metropark Field Station

Bioassay Water Quality Monitoring

Water quality of four water sources (Lake St. Clair, Clinton River, Rouge River, and Detroit River) is being analyzed using a bioassay experiment with water mites. The species Lebertia quinguemaculosa is being used as a bioindicator of healthy water. All three rivers are designated under the EPA as Great Lakes Areas of Concern and Lake St. Clair is being used as a control. Survival rate and activity level of water mites is being analyzed.

Mosquito Larvae Mesocosms

Research into whether water mites can be used as a biocontrol against mosquitoes is being conducted. It has been discovered that the species Lebertia quinguemaculosa eats mosquito larvae and they are being added to mesocosms with mosquito larvae to record the success of mosquito larvae consumption. Hydrachna mites have also been added to a mesocosm as a control, since they do not eat the larvae.

Water Mite Research

At the base of food webs for many organisms in the Great Lakes are small invertebrates that form the source of nutrients for fish and other larger organisms and others that are important carriers of human pathogens. The Ram laboratory, in collaboration with WSU/UD-Mercy post-doc Adrian Vasquez and WSU undergrads, use microscopic and molecular tools to study the predators and prey of water mites.  Increased knowledge of water mites as voracious carnivores of midge and mosquito larvae  and diverse other species is likely to have implications for protecting humans from mosquitoes and understanding how mites impact the food webs upon which Great Lakes organisms depend.
