LOGROÑO Centennial Exhibition
2026-04-29 09:00 - 20:30 UTC
Logroño is a city born on the banks of the Ebro. The river has always been a central axis in the social, scientific and economic life of the city, structuring its landscape and setting the pace of its development. The Casa de las Ciencias, located on the riverbank, symbolizes Logroño’s vocation for dissemination and its commitment to knowledge, the environment and citizen participation. The Ebro has marked the growth of the city, its heritage and its ability to adapt to the challenges of water. From the historic bridges to the modernization of its riverbanks, Logroño has been able to unite tradition and science, incorporating the river into its daily life and the education of new generations.

Logroño’s relationship with the Confederación Hidrográfica del Ebro is active and close: the city has been the scene of pioneering projects in water management, river restoration and scientific dissemination activities. Today, Logroño is an example of the integration of the Ebro as a learning and meeting place for the whole society.

Meetings in Miranda de Ebro
2026-03-26 00:00 - 23:59 UTC
The Centenary Meetings are a series of open conversations designed to bring the centenary of the Confederación Hidrográfica del Ebro closer to the region and its citizens. At each venue, the sessions offer a look at the river and its basin from various perspectives (history, water management, landscape, heritage, and environmental challenges), using an accessible, informative format intended for listening, questioning, and understanding.

In Miranda de Ebro, the session will be held under the title “Conversations around the Ebro basin: living with the river and harnessing its energy” and will address two issues particularly linked to the region and the basin’s history. Participants will include José Adolfo Álvarez González, with the presentation “Floods in Miranda de Ebro: Understanding them to live with them”, and Clemente Prieto Hernández, with the talk “Hydroelectric power and the Ebro basin”.

The session will take place on March 26, 2026, at 6:00 PM, at the Casa de Cultura and is part of the CHE centenary activities program. It will be an opportunity to explore different perspectives on the region: the memory of floods, the need to live with risk, the role of hydroelectric power in the basin, and the historical relationship between water, river management, and environmental transformation.

José Adolfo Álvarez González is an industrial technical engineer and was head of the Automatic Hydrological Information System (SAIH) Service at the Confederación Hidrográfica del Ebro.

Clemente Prieto Hernández is a civil engineer with extensive experience in hydroelectric operations and flood management.

Admission is free until capacity is reached.

MIRANDA DE EBRO Centennial Exhibition
2026-03-17 10:00 - 2026-04-11 21:30 UTC
Miranda de Ebro is a city marked by the river that gives it its name. Located on the border between Castilla y León and País Vasco, the Ebro has been a natural frontier throughout history, but also a place of encounter, exchange and development. The medieval bridge, the old factories and the urban structure itself testify to the fundamental role of water in the local identity and in the daily life of its inhabitants.

The crossing of the Ebro River has boosted the economy, industry, and mobility, turning Miranda into a strategic communications hub and a benchmark for water management in the basin. The city has experienced historic floods, transformed its riverbanks, and adapted to the challenges of modern water management.

Miranda de Ebro’s relationship with the Confederación Hidrográfica del Ebro dates back to the early 20th century, with the regulation of water flows and the improvement of infrastructure to protect the city and guarantee its water supply. Today, Miranda continues to be an example of coexistence with the river and the integration of public water management into urban and social development.

MARCH 5: CHE ANNIVERSARY (1926–2026)
2026-03-05 08:00 - 17:00 (Europe/Madrid)
Today, March 5, 2026, marks one hundred years since the signing of the Royal Decree that ordered the creation of the Confederación Sindical Hidrográfica de la cuenca del Ebro (CSHE), the direct predecessor of today’s Confederación Hidrográfica del Ebro (CHE).

The text was published the following day, March 6, in the Gaceta de Madrid, and established a principle that changed the way water is managed: basin-based planning (the river’s natural unit and its tributaries), above administrative boundaries.

That approach—driven by a technical, long-term vision—sought to coordinate uses, works and conservation under a single territorial logic. A century later, that idea remains valid, with more complex challenges: longer droughts, faster floods, and greater demand for transparency in public management.

Meetings in Reinosa
2026-01-15 18:00 - 23:30 UTC
The Centenary of the Confederación Hidrográfica del Ebro (CHE) opens a space for dialogue in Reinosa about the territory, the Ebro Reservoir, and the history that links the city to water management. This meeting is designed to listen, understand, and take a fresh look at a landscape that is part of everyday life in the region.

The meeting will feature Agustín Monteoliva Herreras, who will present “Environmental aspects of the Ebro Reservoir”, and Rogelio Galván Plaza, with the talk “The birth of the Confederation and the Ebro Reservoir”.

The session will take place on January 15, 2026 and is part of the CHE Centenary programme of activities. It will be an opportunity to bring together different perspectives on the reservoir: its current situation, the environmental challenges it poses, and the historical context in which its management is framed.

Agustín Monteoliva Herreras holds a PhD in Biology and is the director of Ecohydros, S. L., an environmental consultancy company based in Cantabria dedicated to the analysis and management of aquatic systems. He has held this position since October 2003 and has taken part in more than a hundred regional, national, and international technical and scientific projects related to inland water bodies, reservoirs, and environmental monitoring programmes.

Rogelio Galván Plaza is a technical engineer in public works and holds a degree in History. He has worked at the Confederación Hidrográfica del Ebro since 1998 and currently heads the Economic and Social Studies Service of the Hydrological Planning Office. As the institutional coordinator of the Water Experts Network, he regularly takes part in technical work and specialist forums on hydrological planning and environmental management of the basin, bringing a historical and social perspective to the analysis of water resources.

REINOSA Centennial exhibition
2025-12-17 11:00 - 2026-02-01 20:30 UTC
Reinosa, located next to the Fontibre springs, is the birthplace of the Ebro and a meeting point for routes, landscapes, and cultures in northern Spain. The city and its surroundings have always been linked to water management, both in everyday life and in the industrial and social memory of the Campoo region. From reservoir regulation to the glassmaking and metallurgical tradition, the Ebro has been an engine of development and a central element of Reinosa’s identity.

The relationship between Reinosa and the CHE is historic. The Ebro Reservoir was planned here, and some of the basin’s first hydraulic infrastructure projects were launched, marking the beginning of coordinated, sustainable management of the resource.
