FLO-2D SOFTWARE’s Post

By coupling SWMM's urban drainage simulation capabilities with FLO-2D's advanced flood modeling features, users can achieve a more comprehensive understanding of flood dynamics within urban environments. This integration enables the simulation of both localized stormwater runoff and larger-scale flooding events, providing insights into how urban drainage systems interact with natural watercourses and floodplains.

  “FloodNet sensors … in New York City”   Urban flooding is affected by several local factors including upstream land use and development; the size of vegetated and impervious areas; population density and human contributions to the sewer system; drainage and sewer design; and physical characteristics, including elevation and watershed topography.   FloodNet, is a low-cost, ultrasonic sensor project designed to systematically collect data on the presence, depth, and duration of street-level floods in New York City.   FloodNet sensors are designed to be compact, rugged, and deployed in a manner that is independent of existing power and network infrastructure. These requirements were implemented to allow deployment of a hyperlocal, city-wide sensor network, given that urban floods often occur in a distributed manner due to local variations in land development, population density, sewer design, and topology. To date, 87 FloodNet sensors have been installed across the five boroughs of New York City. These sensors have recorded flood events caused by high tides, stormwater runoff, storm surge, and extreme precipitation events, illustrating the feasibility of collecting data that can be used by multiple stakeholders for flood resiliency planning and emergency response.

“Improving coastal urban flood control”   The Regional Ocean Modeling System (ROMS) within the Coupled Ocean-Atmosphere-Wave-Sediment Transport framework (COAWST) was recently used to simulate post-tropical cyclone Ida (2021) pluvial flooding for the Jamaica Bay watershed of New York City. The model was modified to capture the volumetric effects of rainfall and parameterize soil infiltration and the stormwater conveyance system. Spatially continuous flood mapping of Ida was developed with a RMS error of 28 cm when compared to high water marks; useful for understanding Ida’s impacts and subsequent mitigation planning. Results showed that over 37.2 km2 of the urban area in the watershed was deeply flooded (deeper than 0.3 m) during the tropical cyclone. Spatial shifting of the storm track within typical 12-hour forecast track uncertainty revealed a worst-case scenario that increased the deeply flooded area to 74.7 km2.  Shifting Ida’s rainfall to coincide with high tide increased the deeply flooded area by 0.3 km2, a relatively small change due to the lack of significant storm surge and the significant pluvial flood area. The application of COAWST to this storm addresses a broader goal of developing the capability to model compound flooding by simultaneously representing coastal storm processes such as rain, tide, waves, erosion, and atmosphere-wave-ocean interactions. The sensitivity analysis results underscore the need for detailed flood risk assessments, showing that Ida, already NYC's worst rain event, could have been even more devastating with slight shifts in storm track proving once again the intricate sensitivity of storm tracking projections. Please see Kasaei et al. (2024) in HESS, “Pluvial and compound flooding in a coupled coastal system modeling framework: New York City during post-tropical cyclone Ida (2021)”.

Ever wondered how some cities stay dry even during heavy rains and floods? It’s all thanks to some amazing geotechnical and civil engineering techniques! First off, geotechnical engineers play a crucial role in understanding the soil and groundwater conditions. They perform detailed hydrological studies to predict how water will move through an area during a flood. This data helps in designing effective flood management systems. One of the key strategies is building levees and flood barriers. Levees are embankments constructed along rivers to hold back floodwaters. These structures are often reinforced with materials like clay and rocks to ensure durability. Flood barriers can be raised or lowered depending on water levels, providing flexible protection against floods. Drainage systems are another critical component. Advanced urban drainage systems are designed to quickly channel excess water away from streets and buildings. This includes everything from underground tunnels to permeable pavements that allow water to seep through and reduce surface runoff. Let's look at some real-world examples in the U.S. The city of New Orleans has invested heavily in flood protection systems following Hurricane Katrina. The Greater New Orleans Hurricane and Storm Damage Risk Reduction System (HSDRRS) includes levees, floodwalls, and pumps designed to protect the city from storm surges and heavy rains. Another impressive example is the Miami-Dade County's flood management plan. The county employs a combination of seawalls, pumps, and advanced drainage systems to manage flood risks from both heavy rains and rising sea levels. These efforts are crucial in safeguarding the city against the increasing threat of coastal flooding. Incorporating these techniques into urban planning is vital for creating resilient cities that can withstand the challenges posed by climate change.

Connectivity in urbanscapes can cause unintended flood impacts from stormwater systems Abstract Urban flooding is intensifying worldwide, presenting growing challenges to urban communities. We posit that most of the flood management solutions currently employed are local in nature and fail to account for ways in which the space–time connectivity of floods is exacerbated by built infrastructure. We examine the 2014 flood in Southeast Michigan to identify key factors contributing to urban flooding and explore the implications of design choices on inundation. Findings reveal that stormwater infrastructure that neglects flood spatial connectivity can be ineffective in mitigating floods, leading to inundation even in the absence of local rainfall. Different configurations of network connections—including interfaces with natural channels—can significantly impact upstream surcharge, overflowing manholes and inundation conditions. These results emphasize the need to consider interconnectedness of flood processes in urban watershed systems to mitigate limitations inherent in the design of flood control and warning systems, to enhance urban flood resilience.

Your city's drainage system could secretly worsen floods, even when it's not raining in your neighborhood. 🌊 A groundbreaking study from the University of Michigan reveals that urban flooding is far more complex than previously thought. Researchers found that stormwater infrastructure designed to prevent flooding can sometimes exacerbate the problem due to unexpected connectivity between different city areas. The team simulated the catastrophic 2014 flood in Southeast Michigan using advanced modeling techniques. They discovered that areas can flood without local rainfall, as water from nearby regions can flow through interconnected drainage systems. This phenomenon, termed "flood connectivity," challenges current flood management practices and FEMA flood maps. The study highlights the limitations of local flood mitigation solutions. In some cases, drainage systems designed to maximize water outflow increased flooding in certain areas. This counterintuitive finding emphasizes the need for a more holistic approach to urban flood management that considers the entire watershed system. These insights call for a re-evaluation of urban planning and flood prevention strategies. Cities may need to update their infrastructure designs, considering local conditions and the broader impact of interconnected systems across urban landscapes. TL;DR #1 - Urban flooding can occur in areas without local rainfall due to interconnected drainage systems #2 - Current stormwater infrastructure can sometimes worsen flooding instead of preventing it #3 - Flood management strategies need to consider entire watershed systems, not just local conditions #4 - FEMA flood maps may underestimate flood risks by not accounting for infrastructure connectivity #5 - Advanced modeling techniques are crucial for understanding complex urban flood dynamics #UrbanFlooding #Infrastructure #FloodManagement #CityPlanning #WaterSystems

Flood storage behind walls can significantly delay the arrival of flood waves to downstream areas. However, when these walls fail and release stored floodwaters, a surge occurs, often triggering additional failures downstream. This cascading effect amplifies the frontal wave and increases peak discharge, leading to more severe flooding impacts.
