Manipulation with flow rates in water bodies - the possibilities for inhibition of cyanobacterial blooms development
Maršálek, Blahoslav ; Šejnohová, Lenka ; Vinklárková, Darina ; Plotěný, Miroslav ; Jančula, Daniel
If we compare the sediment capping by active barriers to protect the phosphorus release from sediments with other technologies of manipulation with methods of water discharge, it is clear, that by well-considered manipulations with water discharge, it is possible to reach the same (comparable) results with lower costs and with lower ecotoxicological and limnological risks. By the manipulation of water level, it is possible to reduce cyanobacterial bloom development as supplemental or supporting measure, but the effects may differ in different water bodies and thus it must be consulted always with specialists.

Detection and localization of cyanobacterial inoculum in the sediments - use knowledge of life strategies to minimize health risks
Šejnohová, Lenka ; Maršálek, Blahoslav ; Novotná, Zlatica ; Maršálková, Eliška
Water bloom (WB) is a global problem that is particularly closely linked with increased inputs of phosphorus to surface waters.. The subsequent accumulation of nutrients in the tank for the development not only of cyanobacteria in the water column, but also their survival in resting stages in the sediment. The quantity (amount) of inoculum (source) of cyanobacteria in the sediments is the primary factor, along with nutrient and climatic conditions, correlates with the resulting amount of algae in the water column during the summer season. Cyanobacterial resting stages in sediments require specific conditions for survival, which moreover genus from the genus (or species), cyanobacteria differ. Knowledge of the life cycle of cyanobacteria is therefore an essential prerequisite for starting a guide to environmentally friendly, with the current low cost of funds, limit the development of WB.
