Rainfall and groundwater interpolation
Kriging and related methods estimate fields between stations, with an error surface that shows where the estimate is weakest.
GCRI · Water Nexus
Spatial statistics fills the space between gauges: interpolating rainfall and groundwater levels, estimating what an ungauged catchment would show, and stating how uncertain the map is where data are thin.
Spatial statistics and geostatistics analyse data that vary across space, accounting for spatial dependence. They estimate values at unsampled locations and test for spatial patterns. In water, climate and hazards and binesaziya girîng, spatial statistics produce continuous hazard and exposure surfaces with uncertainty. They reveal geographic clustering of risks and vulnerabilities across sectors. The canonical description is on STEM Commons.
Kriging and related methods estimate fields between stations, with an error surface that shows where the estimate is weakest.
Model parameters and frequency curves are transferred from gauged to ungauged catchments by similarity, with the transfer error stated.
Water-quality exceedances and outbreak reports are tested for spatial clustering before a cause is suggested.

Predictions are tested using spatial cross-validation that respects dependence. Uncertainty maps are compared with independent observations.
| Kontrol bikin | How it is done |
|---|---|
| Cross-validation | Stations are withheld in turn and predicted; the error is mapped |
| Variogram review | The spatial model is inspected, not assumed |
| Edge effects | Estimates near borders and coasts carry their larger uncertainty |
Results depend on the scale and zoning of analysis. Sparse or clustered sampling limits prediction in unsampled areas.
Assembled from the Nexus Standards area profile Standardên xetera avê: the hazards it names, the pergalan and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.

Layers enter with their rights, are aligned, analysed and checked for uncertainty, then released after public-safe review; a map is a governed spatial claim.
