This English edition is a curated editorial selection of the references TerraNava uses most often when discussing hydrology, drought, flood risk, governance and territorial decision-making.
These sources offer a strong starting point because they combine institutional authority, hydrological method and direct usefulness for technical framing.
A core technical manual for measurement, analysis and hydrological practice.
Why it matters. It gives TerraNava an internationally recognised basis for hydrological language, observation logic and practice.
The central regulatory frame for river basin planning and water governance in the European Union.
Why it matters. It is essential for any hydrological or institutional work linked to basin planning in Spain and Europe.
Public reference cartography for flood hazard and return periods in Spain.
Why it matters. It anchors territorial flood reading in an official public frame instead of generic hazard claims.
The point is to help non-specialist readers start from a clear sequence rather than an unordered pile of sources.
Start with the Water Framework Directive, then move into basin planning references and European water resources assessments.
Use SNCZI and hydrological guidance before making territorial or institutional claims about exposure and return periods.
Connect IPCC water-cycle readings with WMO and operational climate references before discussing drought and hydroclimatic pressure.
This English page is a curated first wave. The full evidence layer continues to grow through TerraNava’s methodology, HydroRisk and direct technical work.
