Table 4. Description of combined scenario.

SCENARIO DESCRIPTION
Scenario 4 – ‘BGI implementation + planned ordinary maintenance’ This scenario proposes the implementation of BGI from 2030 (as in Scenario 3) and ordinary maintenance actions from 2050 (as in Scenario 2).
Scenario 5 – ‘Replacing infrastructure + Thames Defences extraordinary maintenance’ This scenario proposes the replacement of the stormwater and drainage systems at the lifecycle end in 2046 and 2087 (as in Scenario 1) and the modification of the Thames Defences around 2090.
Scenario 6 – ‘Scenario 4 + Scenario 5’ This scenario suggests the implementation of the bundle of actions of Scenario 4 and, from 2070 onwards, that of Scenario 5.
Scenario 7 – ‘Scenario 6 + BGI increase’ This scenario proposes the implementation of the same actions as Scenario 6 while doubling the areas of the BGI.
