Just T. & Královcová P.: Needs to Update the Restoration Measures in Water Management Planning in th
ve vodohospodářském plánování
In relation to joining the European Union by the Czech Republic, in the first period of the water management planning investment measures such as longitudinal water bed restoration or making migratory/dispersal barriers permeable were proposed as a part of improving morphological/ecological state of water courses in the Czech Republic.
At present, it is clear that the above tool is insufficient. Investing into longitudinal watercourse restoration only, it is not possible to significantly influence the state of the watercourse network in the country. Many watercourse stretches, in the past unsuitable technologically shaped or otherwise modified by machinery, have undergone some natural succession development. Thus, intensive restoration measures would be unnecessarily strong and expensive. The Nature Conservation Agency of the Czech Republics Expert Group for Water Ecosystems is proposing to delineate a framework category of watercourse stretches, where it shall be required and useful to improve morphological/ecological state of water courses. The framework category should be further divided into these implementation categories: A) Watercourse stretch in the open landscape where intensive restoration measures are needed, mostly to be built; B) Watercourse stretch where morphological/ecological state cam be improved by less intensive or discontinuous restoration measures incl. non-building ones, by using spontaneous natural processes and in general, by implementing close-to-nature or nature-based management; C) Watercourse stretch in a built-up area or in its proximity, where flood control/flood preventive measures should be implemented (built-up area restoration). D) Local restoration measures, most often making a watercourse permeable for wildlife migration and dispersal. In addition, a system how to the individual watercourse stretches should be classified within the above categories is also proposed. Due to high water course diversity and variability, it is not appropriate to try to develop a very exact detailed classification system e.g.using ranking. The stretches can be classified by expert opinion, taking into account other conditions and assessing dominant features, supporting listing the individual stretch into the particular category.
