Coastal communities worldwide are seeing stronger storm surges, more powerful waves, and potential devastation for homes, infrastructure, jobs, and a way of life. Celso Ferreira, an associate professor in the Sid and Reva Dewberry Department of Civil, Environmental, and Infrastructure Engineering at the ��AV College of Engineering and Computing, studies the impacts of these threats and suggests ways to manage them.

In May 2023 he co-authored a paper, Jobs at Risk: Sea Level Rise, Coastal Flooding, and Local Economies. “This study is the first to evaluate potential future impacts of flooding from sea level rise and climate change to people’s jobs and incomes. This new methodology provides a more equitable analysis of the impacts of climate change and a vision into its potential implications for the region,” said Ferreira.

According to the study, approximately 263,500 jobs and $11.1 billion in wage income will be threatened by 100-year flooding in the Chesapeake Bay region by 2050. The nonprofit Resources for the Future, with whom Ferreira co-authored the paper states, “These (jobs) figures represent 3.3 and 5 percent of all jobs in the Chesapeake region now and in 2050, respectively. The study also identified several flooding ‘hot spots’ around the region—counties and cities in Maryland and Virginia where 25 percent or more of jobs are flood-exposed.”

“Working with MDDNR and TNC allows our research to directly impact decision-making at the state and local level. It has been a tremendous experience to see our research translated for stakeholders so they can benefit from the science that Mason is producing.”

In addition to quantifying the economic impact, the paper recommends ways to prepare for it. The recommendations include aiming government spending at developing areas outside current and future flood zones; giving coastal communities financial aid but with the condition that businesses are in areas with limited exposure to flooding; providing aid to enterprise zones that incorporates requirements for resilience, such as infrastructure changes to reduce potential flood damage; using FEMA dollars to relocate businesses to different areas within their existing community but out of flood zones; and encouraging communities to change zoning rules to account for climate change.

In a related project with The Nature Conservancy (TNC) and the Maryland Department of Natural Resources (MDDNR), Ferreira and colleagues are assessing the ability of tidal wetlands, marshes, and sea grass beds to absorb storm surges and waves, protecting developed areas.

Ferreira says, “We place sensors that measure wave energy across the coastal habitats during extreme coastal storms, capturing unique data documenting its flood protection capacity. We then use computer models to predict future scenarios through 2100, with different projections of sea level rise focusing on coastal flood protection. We are looking at how will these ecosystems provide coastal protection into the future.”

These coastal barriers are essential to absorbing destructive storm surges. The first few feet of tidal marsh can reduce wave energy by 90 percent, according to TNC. In addition, marshes can trap tidal water sediment, allowing them to grow naturally with sea level rise. “Living” shorelines improve water quality while creating a habitat for fish and increasing biodiversity.

Nicole Carlozo of MDDNR says, “The data collected will help us make better decisions about where to restore and protect coastal habitats and make decisions about coastal restoration strategies. For example, how wide does a marsh need to be, to provide protection benefits.”

Researchers believe that their findings will provide input for statewide models to understand how habitats will transition as sea levels rise, allowing Maryland to make strategic decisions about anticipating and responding to such changes.

New lab closes the loop on water sustainability

The water that pours out from your kitchen faucet goes through a lot to make it to your home. Assistant Professor Kirin Emlet Furst wants to use her new high-tech Water Systems Chemistry Lab at the Potomac Science Center to close the loop on water and increase the efficiency of those processes by taking a systems approach.

Furst, a faculty member in the Sid and Reva Dewberry Department of Civil, Environmental, and Infrastructure Engineering, believes a systems approach is the best way to solve the world’s safe water problems. “Our research lab is primarily focused on removing organic contaminants in drinking water systems and potable reuse systems,” says Furst.

The water treatment process has many steps: source water protection, water treatment, the distribution of the water, and what people are actually exposed to in their homes. “A lot of researchers and research labs focus on one of these processes, but we have projects that touch each part of the water system,” Furst says.

Furst’s main research interest is in reducing disinfection byproducts caused by reactions between dissolved organic materials and water disinfectants. The disinfectants used in water are essential to preventing water-borne pathogens, but when they react with materials that remain in the water, they can create toxins that have numerous health effects.

“To solve the disinfection byproducts problem, we have to look at the bigger picture. It’s hard to test their effects, and there are dozens of opportunities for these toxins to be introduced, so we can’t look at one stage in the process,” she says.

Furst and the graduate and undergraduate students in her lab are also working on ways to increase affordable water treatment methods for low-income areas and increase the treatment and reuse of wastewater. In addition, some of her graduate students are looking into creating new types of filters, others at reducing phthalates.

The advanced equipment in her lab gives her and her students the ability to tackle numerous parts of the water treatment systems, says Furst. And she is looking forward to the new and innovative projects her undergraduate and graduate students will take on.
