ImpoundsRiver Hull

The River Hull tidal surge barrier is a flood control gate located on the

Humber Estuary, and flooding the areas of the city which are near to the river, or susceptible to flooding. It is held horizontal when not in use, and turns 90 degrees before being lowered to the riverbed in the event of a tidal surge. It is the second largest flood barrier in the United Kingdom after the Thames Barrier in London
.

The barrier was opened in 1980, and since then, has closed over 30 times as a preventative measure during tidal surges. A proposed lagoon to control tidal flooding in the Humber Estuary would render the River Hull non-tidal. The barrier was

grade II listed
in 2017, with David Neave describing it as a prominent Hull landmark.

History

The need for the barrier arose after severe flooding of the city from a tidal surge in 1969.

British Steel Corporation had rolled steel to, at that time.[6]

Construction on the barrier was started in January 1977, with projected opening date of August 1979, however, difficulties in the building phase led to schedule slipping. The barrier was opened on 15 April 1980 by Dennis Matthews, chairman of the

Yorkshire Water Authority.[note 1][8][9] The gap between the two towers is 98 feet (30 m) wide and 85 feet (26 m) high to allow shipping to access the river beyond the barrier.[10] The large barrier is stationed in a horizontal position when not in use, but rotates 90 degrees and is lowered when a tidal surge is forecast. The barrier then interlocks into a sill built into the riverbed.[11] When not in use, the barrier's position elevated above the river between the two towers has been described as looking like an "..up and over garage door".[12] The River Hull tidal surge barrier is the second largest flood barrier in the United Kingdom; only the barrier on the River Thames is larger.[13] The height of the two towers is 98 feet (30 m), and the movable barrier that spans the two towers weighs 202 tonnes (223 tons).[14] The barrier can be deployed within 30 minutes of a flood warning.[15] Whilst there are motors that power the barrier into action, if any of them fail, the barrier can be hand-cranked into position within 30 minutes.[16]

In 2010, the barrier was refurbished during a 40-day work period with maintenance being carried out some 98 feet (30 m) in the air. The £10 million work was completed in October 2010.[17]

Writing in The Buildings of England; Yorkshire : York and the East Riding, David Neave said that it was; "..an elegant arch..." and "at night when the glazed staircases to each tower are illuminated, it is a prominent landmark."

grade II listed in 2017, with the citation stating that; "the barrier successfully combines functional engineering with aesthetic quality in a slender and dramatically sculptural arch of angular planes".[5]

Flooding history

in December 2013

Since the barrier was installed in 1980, it has been closed on average once a month every year.[19]

  • 1657, a tidal surge left the city under 4 feet 11 inches (1.5 m) of water[20]
  • September 1966, 16.7 feet (5.09 m) tide[21]
  • 29 September 1969, 16.72 feet (5.10 m)[22]
  • January 2005, 15.9 feet (4.8 m) tide[23]
  • November 2011, 16 feet (4.9 m) tide[24]
  • December 2013, Storm Xaver produced a tide of 19 feet (5.8 m)[25]

Lagoon Hull proposal

In 2019, a proposal to build a lagoon in the Humber Estuary was unveiled. This would involve making the River Hull non-tidal, but no mention was made in the proposal about the River Hull Barrier.[26]
