Euromediterranean Network of Experimental and Representative Basins  (ERB)

Small hydrological research basins – clickable map and inventory of basic metadata

Braunschweig declaration-the need for a global network of hydrological research basins

ERB Newsletters

The Euromediterranean Network of Experimental and Representative Basins (ERB) is an open association of 20 European countries operating and managing well instrumented experimental and representative basins for hydrological and environmental research on a long term basis. The ERB network promotes the exchange of basin information and the cooperation in international programs as FRIEND, HELP and PUB. Information is disseminated through Newsletters. The Steering Committee of ERB consists of National Correspondents nominated by the UNESCO-IHP National Committees. ERB was established in 1986 and has organised eleven biennial conferences since its beginning.

The main objectives are :

Scientific topics and conferences:

Despite the large diversity of hydrological problems in our countries there appears always a convergence of hydrological topics of common interest in small basin research to formulate themes of our conferences to which scientists of all member countries can contribute. Examples are: hydrological monitoring, runoff generation, hydrological and environmental modelling, biogeochemical processes, extremes, uncertainties in data and model concepts, effects of natural and man-made changes, erosion, sedimentation, hillslope processes, etc. The organizing country may also select topics of more national or regional interest.

The biennial conferences are very important occasions to present and discuss research and to exchange experiences. Especially young scientists can benefit from these meetings by presenting their (PhD) research, discussing their ideas and exchange data to test their hypotheses and model concepts.

Scince 1986 scientific topics of common interest were discussed during ERB conferences:

The ERB network is in close contact with other European countries to exchange basin information and cooperate in international programs such as FRIEND, namely Northern European FRIEND Project 5 „Catchment hydrological and biogeochemical processes in changing environment“. Both the ERB and NE FRIEND Project 5 groups recognise the benefits of close co-operation. Therefore, joint meetings and information exchange are organized.

The conditions to become a member country are :
