Digital Twin Technologies for Building Healthy, Resilient, and Equitable Communities By following this initiative you will get updates about new events, maps, and tools! A digital twin mirrors the reality of human and environmental geography. Healthy, resilient communities offer social, physical, and mental well-being to all residents and equity in services, access, and exposure to hazards. Our Sponsors and Partners A special thanks to the NASA Earth Science Technology Office (ESTO) and the Equity and Environmental Justice (EEJ) program. In addition, many collaborating entities help us advance healthy community initiatives across Hampton Roads. Our Focus We are developing technologies to apply the latest advances in Earth Observations, IoT sensor networks, GIS, and environmental models and linking them in Digital Twin that mirrors the real world. The Digital Twin provides for collaborative analysis, testing what-if scenarios, and linkage of real-world data and simulation and modeling to enhance the capacity of end-users to make informed decisions. Earth Observations We apply massive volumes of EO satellite data from NASA, NOAA, EU Copernicus constellation and Uncrewed Autonomous Systems to map flooding and pre-cursor events, validate hydrodynamic models, and predict future sea level rise. Human Health and Resilient Communities We develop data and algorithms to promote quality of life with and equity in safe neighborhoods that are resilient to natural hazards. Geospatial Data and Tools Geospatial data and models tie together Earth observations, sensors, flood models and human health and enable analysis and visualization. Predicting Flooding and Sea Level Rise Hydrodynamic models are essential to risk assessment and disaster response. Sea level rise science is crucial to developing future scenarios for planning. We link these engineering and science disciplines to develop decision support systems. Transportation Resilience Geospatial data and models tie together Earth observations, sensors, flood models and human health and enable analysis and visualization. This hub effort includes data and analysis tools for Natural and Nature-Based Features (NNBFs) to promote sea-level adaptation and flood hazard mitigation. Technology Development and Applied Projects Projects in service to Hampton Roads from aircraft to people and everywhere in between. Frequently Asked Questions Common questions you may be asking about our Healthy Communities initiative. What is the water quality of the bays and rivers in our area? Where are vulnerable populations susceptible to flooding? Are public safety, food, and workplaces accessible? What impacts (and where) will sea level rise affect our area? What if sea level rise accelerates? How might this affect our quality of life? The water quality of the bays and rivers near Norfolk, Virginia, can vary depending on several factors. The Chesapeake Bay, located near Norfolk, has experienced water quality issues due to nutrient pollution, but efforts to reduce pollution have led to improvements. The James River, which flows through the area, has shown improvements in water quality in recent years, thanks to pollution reduction efforts. During severe floods in the Hampton Roads region, access to public safety, food, and workplaces can be limited or disrupted. In some areas, floodwaters can make roads impassable, making it difficult for emergency responders to reach those in need. Floods can also damage infrastructure, including electrical systems and water treatment plants, which can lead to disruptions in food and water supplies. Additionally, flooding can impact workplaces, causing business closures and disrupting employment. While there are measures in place to help mitigate the impacts of flooding, such as emergency response plans and evacuation procedures, severe flooding can still pose significant challenges to accessing essential services and resources. Sea level rise has had profound impacts on Hampton Roads, Virginia, a coastal region situated at the confluence of the Chesapeake Bay and the Atlantic Ocean. The area, known for its military bases, historical sites, and vibrant communities, is facing significant challenges as the sea encroaches upon its shores. Rising water levels have led to increased coastal flooding, threatening infrastructure, homes, and businesses. The region is also experiencing saltwater intrusion, endangering freshwater supplies and delicate ecosystems. You may find areas likely to be impacted here. Have an Idea or Concern? A Digital Twin can host an infinite variety of data that replicate the real-world. Our data focus on coastal hazards and human health. Have we missed anything? Do you have an idea for a new dataset or a problem or concern that could be solved with new data? Please send us your ideas at tallen@odu.edu Events Want to learn more or participate? Here are some upcoming academic, research, and community events where the project is being shared. List of Upcoming Events Stay Informed Follow to be updated on the latest changes!
