HC Deb 23 January 1997 vol 288 cc700-1W
Mr. Dalyell

To ask the Minister of Agriculture, Fisheries and Food, pursuant to his letter of 1 November 1996, reference 101871, what study he has made of Dixon and Tawn's findings on storm surges; and what action he proposes. [10825]

Mr. Boswell

Dixon and Tawn undertook a theoretical statistical analysis.

Further study using actual data gathered from the national network of tide gauges has confirmed that non-random events, such as astronomic tides, influence water level estimates. Their range, between an overestimate of 250 mm and an underestimate of 100 mm, falls within the current allowance for water level estimates used for the design of sea defences.
