The Global Centre for Risk and Innovation (GCRI)
The science, technology, engineering and mathematics Water Nexus rests on. Each method has a canonical page in the STEM Commons, hosted by GCRI, and a page here on how it is applied in this field.
GCRI · Established · service level R0
The Water Nexus STEM foundation is the set of canonical methods its findings depend on, from hydrology and water science to uncertainty quantification and model validation. For the Consortium, Water Nexus stewards hydrology and water science as well as water and environmental engineering. Each method has a canonical STEM Commons page and a page here on its use in the water field.
Fig.The methods this platform draws on and what each one feeds. Design, not a record.
Rivers, lakes and how far each division sits from mapped surface water, shown for Central Asia as an example geography for this subject.
Water risk needs a hydrological core (hydrology, extreme value statistics, forecasting), observation (Earth observation, sensors, geospatial methods), spatial statistics to move between gauges and basins, uncertainty quantification to carry errors to decisions, and environmental engineering for the infrastructure that delivers water.
When a finding names the methods it depends on, a reader can see its assumptions and limits, and an expert in that method can challenge it.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| STEM Commons | The shared reference of science, technology, engineering and mathematics methods for the Nexus network, hosted by GCRI, with one canonical page per method and a named steward platform. |
| Steward platform | The platform that maintains the canonical description of a method in the STEM Commons and reviews how other platforms apply it. |
| Hydrology and water science | Hydrology studies the movement, distribution and quality of water across the land surface, subsurface and atmosphere. |
| Water and environmental engineering | Water and environmental engineering designs systems for water supply, wastewater treatment, drainage and pollution control. |
The bodies and documents this page is read against. Status and editions change; each link goes to the issuing body.
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.
