The SAIH system: the sensor network watching Spain's rivers
The Automatic Hydrological Information System monitors flow rates, reservoir levels, and rainfall in real time across all Spanish basins. Learn how this critical infrastructure works.
Early Warning
How a flood alert system works
From gathering meteorological data to issuing warnings to the public, we analyze every stage of the process that anticipates river flooding and saves lives.

Reservoirs in Spain: dam safety and flood management
Spain has more than 1,200 large dams. We explore how reservoirs are managed during heavy rainfall events and the safety protocols that protect downstream populations.
Safety
Flood emergency preparedness guide
Practical tips to prepare before, during, and after a flood. Includes checklists, family plans, and recommendations from Civil Protection.
Hydrology
The hydrological cycle: from rain to runoff
Understanding the water cycle is essential to understanding floods. We analyze how precipitation becomes runoff, what factors influence it, and why the soil sometimes cannot absorb more water.

Cold drop and torrential rains in the Mediterranean
The cold drop is one of the most feared weather phenomena along the Spanish Mediterranean coast. We explain how it works, how it relates to DANA, and why autumn is the highest-risk season.
Hydrology
Rivers and watersheds of Spain: a complete guide
A detailed guide to Spain's main hydrographic basins, their most important rivers, the river-basin authorities that manage them, and how water management is organized across the country.
Environment
Climate change and floods: what the data says
Scientific data shows a trend toward more extreme rainfall events. We review the evidence, IPCC projections, and what it means for flood risk in Spain.
Technology
Weather radar and AEMET: how rain is detected
Weather radars are essential tools for detecting precipitation in real time. Discover how AEMET's radar network works and how to interpret its imagery.
History
Major floods in Spain: lessons from history
From the 1957 Valencia flood to the floods of the Ebro, we revisit the most devastating events in Spanish history and the lessons learned that have shaped today's risk management.
Safety
Civil Protection and flood emergency plans
Learn about the structure of Civil Protection in Spain, the special plans for flood risk, and how administrations coordinate to respond to emergencies.
