Factors affecting the occurrence of littoral vegetation in a reservoir with storage function

This Ph.D. thesis focuses on the characteristic of littoral vegetation in reservoirs with a storage function and on the factors that may affect it. The current state of the littoral vegetation in different types of biotopes was detected by a detailed survey of the littoral in Lipno reservoir. Complexes of environmental factors characteristic for different types of biotopes were described. The dynamics of littoral vegetation in response to changes in water level fluctuations was monitored in a protected bay during three years. Based on the results, the vegetation zonation was described in the eulittoral zone of an aquatic ecosystem with irregular fluctuations in water levels. The thesis also deals with the use of a breakwater structure to protect littoral vegetation in erosion exposed biotopes. The results of all three studies are used as a basis for proposals for supporting the development of littoral vegetation in the eulittoral zone in reservoirs as defined in the Water Framework Directive
