Excavation and treatment of sediments
 Pokorný, J.
Methods aimed at reduction of internal nutrient loading in eutrophic water bodies are explained. Development of blue greens results both from external and internal loading. Eutrophic sediment in which anaerobic processes také place releases phospohorus which results in uncontrolled development of water blooms. Examples of hypertrophic lakes in which restoration was realised with success are given. Principles of sediment treatment aimed at immobilisation of phosphorus are explained. Aeration, P precipitation, nitrate application are described. Techniques for removal of eutrophic sediment both by classical and suction dreges are described. Relevant scientific literature is given.
