01In brief

The short answer.

Water Nexus tools are the public technical views the platform releases on water: maps and model descriptions, each with its time and space reference, sources, licence and uncertainty. Analysis runs in Nexus Foundry for authorized projects, and data that is not released is not available through these pages.

02Canvas

Scoping to review.

Canvas · scoping to reviewDesign, not a record
Data and technical methods: build, test and release in Nexus FoundryA request opens a workspace; data are ingested and validated; the model is built and tested on held-out data; an independent gate approves release with limits; the workspace is stood down and the record kept. Design of the process, not a record of a run.

03Geography

Digital demand and connectivity in the United Kingdom and Ireland.

Urban demand centres and the hubs that anchor digital and data infrastructure, shown for the United Kingdom and Ireland as an example geography for this subject.

05What the tools answer

Three questions every water tool should answer about itself.

  • Which basin, period and spatial resolution it represents.
  • Which inputs it uses, with evidence labels, and which it lacks.
  • What decision it is fit for, and what it is not fit for (for example, a regional drought map is not a well-siting tool).

Released maps carry the indicator register; model descriptions are on models and scenarios.

06Build environment

Working with the tools.

Analysis runs in Nexus Foundry for authorized projects. Public pages show released views only, each with its time and space reference and its rights.

07Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
Public-safe releaseA recorded decision on the detail at which a layer may be published without exposing sensitive sites or people.
Coordinate reference systemThe definition that ties coordinates to locations on Earth, catalogued with EPSG codes.
Model cardA short document describing a model's intended use, training data, performance and limits.
08Sources

10Questions

Questions and answers.

Can I use the data?
Each released view states its licence and terms. Data that is not released is not available through these pages.

The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
