PrefaceThis volume comprises papers presented at the fourth conference of the European Network of Experimental and Representative Basins (ERB), which was founded in 1986.The main aims in establishing the Network were to encourage international contacts between scientists and research teams through meetings and data exchanges, and to encourage the creation of joint research projects.The network is managed in Europe by National Correspondents nominated by the Unesco -IHP National Committees of the member countries -Belgium, France, Germany, Italy, Netherlands, Portugal, Spain, Switzerland, UK and, our newest members, the Czech and Slovak Republics.The ERB organises International Conferences at two-year intervals. To date these have been Wageningen, Netherlands September 1992Oxford, EnglandIn addition, an ERB Newsletter is published approximately twice yearly and distributed to 250 scientists worldwide. This covers information about national and intemational activities, and projects, research findings and publications, as well as progress with the ERB Inventory.The ERB Inventory (ICARE) provides a computer database of nearly 100 basins, including their physical characteristics, instrumentation, data, research aims and key publications. The database is maintained and continuously updated by the CEMAGREF in Lyon, France, with information provided by the National Correspondents.The ERB Inventory can be accessed to obtain information about basins which fulfil certain criteria; for example it has been used in the FRIEND Project to identify small research basins in northem and western Europe concerned with physical processes of streamflow generation.The first phase of the ERB Network (1986-91) was concemed with establishing the Network, identifying basins and obtaining descriptive data. Scientific topics of common interest were discussed and several research teams prepared joint research bids to the CEC.The second, and current, phase of the ERB Network has been concemed with moving on from the establishment of the Network to its use. The ERB Inventory has reached a level of completeness where it can be used operationally by scientists to exchange and analyse research results. This offers wide opportunities to perform comparative basin studies.Basin comparisons have been made for many years. This Conference puts special emphasis on the various methods used in such comparative work. The Conference theme focuses on methods of hydrological comparison, and deals with both water quantity and quality.
IntroductionThis Publication includes 20 papers from western and central Europe. They cover reports from a broad range of current research on hydrologic comparisons carried out in a number of study sites across Europe and using a wide range of methodological approaches.Each Chapter is presented in the form of a self-contained paper, with its own abstract and reference list, but may also be viewed as a component of this overall Report.The papers are grouped under broad methodological headings for convenience only: basin studies may...
