Optimization of land use along watercourses and on agricultural land for the sustainable development of the Dresden region on the basis of hydrological, forestry, environmental-psychological and economic research and implementation work

Gewundener Bachlauf mit viel Ufervegetation bei sonnigem Wetter

Short Description

The watercourses linking the city and the countryside are important connections between Dresden and its surroundings. The strong utilization pressure on land as a resource is addressed using the example of watercourses. Here, agriculture is faced with competing demands: On the one hand, there is great economic pressure and the requirements of EU agricultural policy; on the other hand, there are the requirements of the EU Water Framework Directive to achieve good ecological status. Vegetation plays a key role in this. As part of the project, a multifunctional utilization option is being investigated using the example of agricultural forestry (energy wood) along watercourses, which can achieve a balance of interests in this conflict of use.

The targeted use of riparian vegetation, e.g., in the form of suitable trees in the embankment area or in the riparian strip, leads - in addition to the positive effect of shading and as a food source - to an increase in the morphological dynamics and structural quality of watercourses through the associated increase in flow diversity. The TRiMM habitat model developed at the Chair of Hydraulic Engineering can be used to calculate how the discharge and thus flow diversity leads to a highly dynamic spatio-temporal provision of physical habitats for macrozoobenthos over the course of the year. In the OLGA project, the development of water temperature is taken into account in habitat modeling and special emphasis is placed on the accurate representation of low flow conditions in order to assess habitat conditions during the summer months. For this purpose, the shading characteristics of riparian vegetation are implemented in TRiMM depending on the stage of development and the species and the associated influence on water temperature.

In OLGA, a transferable solution for implementing the EU Water Framework Directive is being developed, taking equal account of regional economic relations, the interests of landowners, flood prevention and the participation of the population. The project results intensify the sustainable development of rural areas in the Dresden region through urban-rural cooperation.
