Pathway

Coastal flooding was reported in England, Belgium, and the Netherlands (Editors of Encyclopaedia Britannica, 2011). In the UK, an account recalls that “the sea came out upon the shore” (Chronicle of Florence of Worcester, quoted in Lowe, 1870). This is the earliest record of flooding of the Thames Estuary, as recorded by the Anglosaxon Chronicle of 1099 (Lavery and Donovan, 2005). The Thames overflowed its banks in many places near the river mouth, and a famous estate owned by Earl Goodwin was submerged, and it is alleged that it could not be drained and become the sand bank known as Goodwin Sands (Entick, 1766).

Receptor and Consequence

“The sea-flood sprung up to such a height, and did so much harm, as no man remembered that it ever did before” (Lowe, 1870). Very many men, and innumerable oxen and sheep were buried (Chronicle of Florence of Worcester, quoted in Lowe, 1870). This flood is regarded as one of the notable floods of the River Thames that lead to loss of life (Flood Modeller Suite, 2016). Records suggest that 100,000 people were killed in the UK and the Netherlands by coastal floods in 1099 (Taylor Redd, 2012; Haigh and Bradshaw, 2015).
