AquaFence is a reusable temporary flood and hurricane barrier made by the Norwegian manufacturer AquaFence. It is an alternative to other temporary floodwater control such as sandbags and to the building of permanent seawalls.
AquaFence is a reusable temporary flood and hurricane barrier made by the Norwegian manufacturer AquaFence. It is an alternative to other temporary floodwater control such as sandbags and to the building of permanent seawalls.
The fencing consists of interlocking panels which are waterproof and puncture-resistant, can be bolted down to resist winds, and use the weight of floodwater to hold them in place. [1] [2] [3] Materials include marine-grade laminate, stainless steel, aluminum and reinforced PVC canvas. [3] The panels are reusable and can be stored flat between uses. [4] The technology was designed as an alternative to building seawalls or placing sandbags in the path of floodwaters. [4] [3]
An AquaFence was deployed at the Tees Barrage. [5]
An AquaFence was deployed in Mount Vernon, Washington, in 2008. [5]
Tampa, Florida's only Level I trauma center is at Tampa General Hospital, which sits directly on Tampa Bay at the northern end of the Davis Islands, which are one of the city's lowest-elevation areas. [1] [2] [6] [7] The hospital employs an AquaFence when a hurricane is forecast; erecting the fence requires 60 workers for three days. [1] The fence the hospital uses can withstand storm surges of 15 feet (4.6 m) and wind speeds of 130 miles (210 km) per hour, which can handle a category 3 hurricane. [1] [2] The hospital used the fence for the first time during 2022's category 5 Hurricane Ian. [8] During 2023's category 4 Hurricane Idalia the fence allowed about two feet of water through. [1] It was also deployed during 2024's category 3 Hurricane Helene, successfully protecting the hospital. [9] [10] It was deployed for 2024's Hurricane Milton. [7]
AquaFences have also been used to protect private properties such as luxury homes in flood-prone or hurricane-prone areas. [4]
AquaFence was founded in 1999 and is headquartered in Oslo, Norway. [5]
Cedar Key is a city in Levy County, Florida, United States. As of the 2020 census, its population was 687, down from 702 at the 2010 census. It is part of the Gainesville, Florida Metropolitan Statistical Area. The Cedar Keys are a cluster of islands near the mainland. Most of the developed area for the City of Cedar Key has been on Way Key since the end of the 19th century. The Cedar Keys are named for the eastern red cedar Juniperus virginiana, once abundant in the area.
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves.
Hurricane Katrina was a powerful and devastating tropical cyclone that caused 1,392 fatalities and damages estimated at $125 billion in late August 2005, particularly in the city of New Orleans and its surrounding area. It is tied with Hurricane Harvey as being the costliest tropical cyclone in the Atlantic basin. Katrina was the twelfth tropical cyclone, the fifth hurricane, and the third major hurricane of the 2005 Atlantic hurricane season. It was also the fourth-most intense Atlantic hurricane to make landfall in the contiguous United States, gauged by barometric pressure.
A flood barrier, surge barrier or storm surge barrier is a specific type of floodgate, designed to prevent a storm surge or spring tide from flooding the protected area behind the barrier. A surge barrier is almost always part of a larger flood protection system consisting of floodwalls, levees, and other constructions and natural geographical features. Flood barrier may also refer to barriers placed around or at individual buildings to keep floodwaters from entering the buildings.
The Tampa Bay hurricane of 1921 was a destructive and deadly major hurricane which made landfall in the Tampa Bay area of Florida in late October 1921. The eleventh tropical cyclone, sixth tropical storm, and fifth hurricane of the season, the storm developed from a trough in the southwestern Caribbean Sea on October 20. Initially a tropical storm, the system moved northwestward and intensified into a hurricane on October 22 and a major hurricane by October 23. Later that day, the hurricane peaked as a Category 4 on the modern day Saffir–Simpson scale with maximum sustained winds of 140 mph (230 km/h). After entering the Gulf of Mexico, the hurricane gradually curved northeastward and weakened to a Category 3 before making landfall near Tarpon Springs, Florida, late on October 25. It was the first major hurricane to make landfall in the Tampa Bay area since the hurricane of 1848 and is the last to date. The storm weakened to a Category 1 hurricane while crossing the Florida peninsula, and it reached the Atlantic Ocean early the following day. Thereafter, the system moved east-southeastward and remained fairly steady in intensity before weakening to a tropical storm late on October 29. The storm was then absorbed by a larger extratropical cyclone early the next day, with the remnants of the hurricane soon becoming indistinguishable.
The 1915 Galveston hurricane was a tropical cyclone that caused extensive damage in the Galveston area in August 1915. Widespread damage was also documented throughout its path across the Caribbean Sea and the interior of the United States. Due to similarities in strength and trajectory, the storm drew comparisons with the deadly 1900 Galveston hurricane. While the newly completed Galveston Seawall mitigated a similar-scale disaster for Galveston, numerous fatalities occurred along unprotected stretches of the Texas coast due to the storm's 16.2 ft (4.9 m) storm surge. Overall, the major hurricane inflicted at least $30 million in damage and killed 403–405 people. A demographic normalization of landfalling storms suggested that an equivalent storm in 2005 would cause $68.0 billion in damage in the United States.
The 1848 Tampa Bay hurricane was the strongest known hurricane to impact the Tampa Bay area of the U.S. state of Florida. Along with the 1921 Tampa Bay hurricane and Hurricane Milton in 2024, it is one of only three major hurricanes to make landfall along Central Florida's west coast since Florida became a United States territory in 1821.
Anna Maria Island is a barrier island on the coast of Manatee County, Florida, in the United States. It is bounded on the west by the Gulf of Mexico, on the south by Longboat Pass, on the east by Anna Maria Sound, and on the north by Tampa Bay. Anna Maria Island is approximately 7 miles (11 km) long north to south.
Hurricane Ike caused major destruction in Texas with crippling and long-lasting effects, including death, widespread damage, and impacts to the price and availability of oil and gas. Hurricane Ike also had a long-term impact on the U.S. economy. Making landfall over Galveston as a Category 2 hurricane, at 2:10 a.m. CDT on September 13, 2008, Hurricane Ike caused extensive damage in Texas, with sustained winds of 110 mph (180 km/h), a 22 ft (6.7 m) storm surge, and widespread coastal flooding.
The Tampa Bay area has a humid subtropical climate, closely bordering a tropical climate near the waterfront areas. There are two basic seasons in the Tampa Bay area, a hot and wet season from May through October, and a mild and dry season from November through April.
Flood management describes methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood management methods can be either of the structural type and of the non-structural type. Structural methods hold back floodwaters physically, while non-structural methods do not. Building hard infrastructure to prevent flooding, such as flood walls, is effective at managing flooding. However, it is best practice within landscape engineering to rely more on soft infrastructure and natural systems, such as marshes and flood plains, for handling the increase in water.
Tampa General Hospital (TGH) is a 1,040-bed non-profit hospital, tertiary, research and academic medical center located on Davis Island in Tampa, Florida, servicing western Florida and the greater Tampa Bay region. TGH is one of the region's only university-level academic medical centers. Tampa General Hospital is the primary teaching affiliate of the Morsani College of Medicine of University of South Florida. TGH also features the area's only ACS designated level I adult and pediatric trauma center and has a rooftop helipad to handle medevac patients. Attached to the medical center is the Tampa General Hospital Children's Medical Center that treats infants, children, adolescents, and young adults up to the age of 21.
Hurricane Isaac was a deadly and destructive tropical cyclone that came ashore in the U.S. state of Louisiana during August 2012. The ninth named storm and fourth hurricane of the annual hurricane season, Isaac originated from a tropical wave that moved off the west coast of Africa on August 16. Tracking generally west, a broad area of low pressure developed along the wave axis the next day, and the disturbance developed into a tropical depression early on August 21 while several hundred miles east of the Lesser Antilles. The system intensified into a tropical storm shortly thereafter, but high wind shear initially prevented much change in strength.
The effects of the 1919 Florida Keys hurricane in Texas were the deadliest of any tropical cyclone in the Texas Coastal Bend, killing at least 284 people. The hurricane produced a widespread swath of devastation across the region, exacerbated by the large extent of its winds. The city of Corpus Christi bore the brunt of the hurricane's impacts, contributing to the largest portion of the damage toll in Texas; nearly all of the confirmed fatalities were residents of the city. The storm originated from the Leeward Islands early in September 1919 and took a generally west-northwestward course, devastating the Florida Keys en route to the Gulf of Mexico. On the afternoon of September 14, the center of the hurricane made landfall upon the Texas coast at Baffin Bay. The storm's winds were estimated at 115 mph (185 km/h) at landfall, making it a Category 3 hurricane on the Saffir–Simpson hurricane wind scale. After slowly moving ashore, it weakened and straddled the Rio Grande before dissipating on September 16 over West Texas.
Hurricane Idalia was a powerful and destructive tropical cyclone that caused significant damage across parts of the southeastern United States, especially in North Florida, in late August 2023. The ninth named storm, third hurricane, and second major hurricane of the 2023 Atlantic hurricane season, Idalia formed from a low-pressure area that crossed Central America from the eastern Pacific Ocean. Gradual development ensued as it meandered in the western part of the Caribbean Sea; the system was upgraded to a tropical depression on August 26, 2023, and strengthened into a tropical storm a day later, receiving the name Idalia. It traversed the Gulf of Mexico where it underwent rapid intensification, briefly becoming a Category 4 hurricane before weakening and making landfall in the Big Bend region of Florida as a low-end Category 3 hurricane on August 30. Idalia remained a hurricane as it moved through Northern Florida and crossed into Southeast Georgia; it then pushed into the Carolinas as a tropical storm. On August 31, Idalia emerged into the Atlantic, where it transitioned into a post-tropical cyclone that same day. Later, it passed south of Bermuda, made a counterclockwise loop, then meandered off the coast of Nova Scotia while winding down.
Hurricane Helene was a devastating tropical cyclone that caused widespread destruction and fatalities across the Southeastern United States in late September 2024. It was the strongest hurricane on record to strike the Big Bend region of Florida, the deadliest Atlantic hurricane since Maria in 2017, and the deadliest to strike the mainland U.S. since Katrina in 2005.
North Carolina was severely impacted by Hurricane Helene during late September 2024, primarily in its western Appalachian region, causing at least 101 reported deaths and significant destruction of infrastructure and residential areas across several settlements. After making landfall in the Big Bend region of Florida on September 27, the hurricane began to traverse over land across Georgia as a Category 2 hurricane and into the Appalachian mountain range as a Tropical Storm, depositing record-breaking amounts of rainfall across several settlements in western North Carolina, such as Asheville, Swannanoa, Chimney Rock, Montreat, Lake Lure, and several others.
Hurricane Milton was an extremely powerful and devastating tropical cyclone which became the second-most intense Atlantic hurricane ever recorded over the Gulf of Mexico, behind only Hurricane Rita in 2005. Milton made landfall on the west coast of the U.S. state of Florida, less than two weeks after Hurricane Helene devastated the state's Big Bend region. The thirteenth named storm, ninth hurricane, fourth major hurricane, and second Category 5 hurricane of the 2024 Atlantic hurricane season, Milton is the strongest tropical cyclone worldwide in 2024 so far.
