A short overview on the relations of the 11 sub-projects and their tasks will be given in the following. Basis for this overview are simplified schemes, which combine the three spatial scales, the basic tasks, and their connections to the sub-projects.
The principal approach to derive and valuate the management options starts with the definition of goals and the development, analysis and valuation of scenarios and it ends up with the derivation of the management plan. This approach is show in the following scheme, which also illustrates the fluxes of information and the combination of all project results.
Principal approach to derive a management plan for the Havel river basin.
The three columns (1) ‘Analysis’ (left), (2) ‘Evaluation’ (middle) and (3) ‘Participation’ (right) represent the essential problems and planned research tasks in the Havel river basin. Column (1) summarizes the tasks to analyze the actual state of the Havel, taking into account changes of the river system and already irreversible system states. In column (2) the ecological guidelines are defined on the basis of the results in (1). Goals are derived for an improved system state, based on various indicators. In order to ensure a high practical relevance, information and hints from outside (interested public, regional experts) are used in this development stage as well.
To evaluate needs for action the following deficit analysis compares the actual and the intended system states. Taking into account the needs of various water users management options are derived, which represent the scenario input to the models describing the river system and are evaluated using multi-criterial valuation algorithms. The development concept derived finally includes various participative elements (information and dialogue with the public) and represents the basic fundamentals for a future management plan in the Havel river basin. The horizontal fluxes between the three columns are guaranteed by the strong connectivity between the various sub-projects and their results.
Scales and Themes
The following table illustrates the position of the 11 sub-projects within a matrix of core themes and spatial scales. For comprehensibility reasons, each of the sub-projects is represented only once, though most of the sub-projects are active at more than just one spatial scale.
