The overall goal of the project was to analyse water pollution in three Turkish river basins arising from point and non-point nitrogen sources. This was done by linking an agroeconomic / hydro-(geo)logic modelling system for analysing nitrogen pollution from diffuse sources to an approach to consider point sources and to a hydrodynamic model. For this purpose an interdisciplinary Turkish – German project team consisting of environmental engineers, geoscientists and agro-economists was formed. The German project team was composed of scientists from two universities - the Free University of Berlin (FU Berlin) and the Brandenburg Technical University of Cottbus (BTU Cottbus) - and from two National German Research centres - the Federal Agricultural Research Centre Braunschweig (FAL) and Research Centre Jülich (FZJ) -. On the Turkish side three Turkish universities - Gebze Institue of Technology (GIT), DEU-CEVMER, Izmir and Istanbul Technical University (İTU) gave input to the project. In total, 15 scientists and 4 technicians, who contributed in terms of sampling and analyses, were involved in the project. During the whole allocated time of the project (2004 – 2007), nine official project meetings took place in Turkey and Germany in which the progress of the projects was discussed. The regular exchange of scientists during the whole project period displayed an indispensible basis for the research work in Turkish and German institutions. Thus, three stays of young Turkish scientists in German partner institutions for time periods between two weeks to three months took place between 2005 and 2007. In return, one young German scientist stayed at Turkish Research Institutions for about one month. These exchanges of scientists strongly supported the project. Additionally fifteen field trips were carried out to the study areas in order to collect data. Investigation of diffuse pollution was carried out based on the interdisciplinary agroeconomic / hydro-(geo)logic modelling system RAUMIS – GROWA, which was developed for the management of nutrients in German river basins. The intention was to analyse the possibilities of the transfer and applicability of the model system to river basins in Turkey, respectively to Mediterranean site conditions. In contrast to the diffuse nutrient inputs into rivers, the emissions from point sources were derived directly based on statistical data (number of inhabitants, industries etc.). Additionally a nutrient balance model for the receiving water was applied for the Izmit Bay. The results of the project show that the main objective of the project, i.e. the exemplary implementation of a method for the quantification of nutrient inputs from point sources and from diffuse sources for Turkish river basins has been achieved. In this connexion Turkish and German experiences have been merged successfully. Whereas the Turkish water protection strategies –and hence the developed model tools- were focussed on point source pollution during the last decade, German water protection strategies were focused more on diffuse pollution control –and hence on developing models to control diffuse pollution -. The integration of these tools is a promising way to assess the actual status of pollution of water resources as it is able to quantify the nutrient inputs into groundwater and surface waters from the different sources. It has the potential to be applied in the framework of both, long-term impact assessments of nutrient pollution reduction measures and the derivation of site-adapted water resource development and utilization plans for the sustainable management of nutrient loads. |
