Introduction
Reservoirs in Germany
Drinking Water Reservoirs in Thuringia
Poster: Water and Environment
Minimum requirements for the quality of untreated
water for the preparation of drinking water
Additional requirements for the quality of untreated
water for the preparation of drinking water in view of eutrophication
Natural and antropogenic factors wich affect
water quality
Influence of antropogenic factors
Water Protection, Catchment Aera and Wateshed
Significant sources of water pollution
Waste water problems
Sewage draining away from the conservation areas
Diffuse entries from agriculture
Relationship between nitrate and agriculture (example)
Reduction of pollution from agriculture
Water Quality Management and Lake Restoration
Ecological principles of cleaning waters
Bacterial self cleaning mechanisms
Cycle of material and energie in the pelagic ecosystem
Chemicals and pathogens
Differences between lakes and reservoirs
Short time reservoir management
Types of density flows in reservoirs
Decreasing buffer capacity of emty reservoirs
Variation of water level - influence on banks and
benthic ecosystem
Increasing of trophic state in small water body
Hypolimnic aeration of reservoirs
Example: Oxygen concentration in an eutrophic reservoir
Food web control (Biomanipulation)
Artificial mixing (destratifikation) of reservoirs
Elimination of nutrients by using pre dams
Global problems and strategies
