Content

The restoration and management technics of the lentic (i. e. lakes and ponds) and lotic (i. e. rivers and brooks) aquatic ecosystems, the physic-chemical, biological and ecological effects and estimating an defining the cost-efficiency of different technics. The water protection technics and constructions in the catchment especially for decreasing in most cases the diffuse loading (caused especially by agriculture, forest and peatland management and rural settlement) into aquatic ecosystems. Preparing the plan for the restoration and management of the watercourse and its catchment based on the physic-chemical, biological and ecological diagnosis including the costs and cost-efficiency of the measures. The legislation connected with the management and restoration of the aquatic ecosystems and their catchments.
