The basic scientific aim of the project is to develop management options for the Havel river basin based on the actual scientific and technical knowledge. Taking into account changing natural and socio-economic boundary conditions their influences on water availability and quality and the economic and social conditions of different water users will be derived. Besides scientific goals (derivation of scientific data bases, development of models and tools which are useful do derive management measures) practical goals (like the development of concrete contributions to solve existing problems in the study region) are pursued as well.
Three main scientific goals of the project can be distinguished:
Interdisciplinarity and integration
The scientific tasks of the project are characterized by a high degree of interdisciplinarity, which requires a strong ccoperation between specialists from different fields: Hydrology, hydraulic, landscape ecology, landscape planning, sattelite monitoring). Therefore, the project partners belong both to scientific institutes, regional authorities and private agencies. The working approach and the specific results of the various disciplines must be coordinated and combined to common results and tools, which in the end enable the support of decision finding processes.
This interdisciplinary and integrative approach is achieved at different working platforms:
In summary, the interdisciplinary approach is reflected in using a methodoloy, which combines both data-based (inductive) and theoretically-based (deductive) steps.
Basin and scale driven approach
The questions of water quantity, water quality and water-related management options in the Havel river basin require an approach, which suites the natural structure of the study object. In addition, the relevant processes must be described at different spatial scales and the results obtained at these scales must be combined (up- and downscaling). The scale issue is handeled by modelling different spatial units in different detail: Small river basins less than 200 kmē in size (focus regions), intermediate river basins of about 2.000 kmē (intermediate scale) and the whole Havel basin at the largest scale. This scale driven approach also includes the regionalization of results by transfering results from the smaller to the larger scales.
The project is characterized by a high practical relevance. One indicator is the simulation of spatially and temporally harmonized management measures by use of models, which assure a high practical applicability and validity of results. The transfer of results to practical use, which is enhanced by the partnership of regional authorities like LUA and LVL, will start already during project runtime. Another indicator of the practical orientation is the participation of water users and stakeholders in the derivation of guidelines and the development of management options (see sub-project 9). Last but not least, the development of a GIS-based analysing and evaluation tool by sub-project 8, which will be provided in the end, clearly indicates the practical relevance of the project.
