An accompanying User Guide is available to support the use of these datasets, and a full list of source datasets and data limitations can be found in the project technical report. This dataset shows the number of constraints to enhancing surface roughness for natural flood management (NFM). Areas with fewer constraints may offer greater potential for implementing measures to increase surface roughness and support NFM objectives.

Only limited inferences of habitat are possible by assessing Phase 1 habitat codes. Surface roughness could be derived from more direct measures than habitat scoring Instead of using a coastal buffer, ideally all areas would be masked out that do not have any urban features dowqnslope of them.

Habitat constraints included existing high biodiversity-value habitats that are either unsuitable for conversion to another habitat type or where habitat restoration is the preferred management approach. Coastal proximity constraints included areas within 500 m of the coastline, where interventions are considered unlikely to deliver significant NFM benefits. Urban constraints included existing built environments, such as roads and buildings, which are unsuitable for conversion to habitats with higher surface roughness.
