Applying multi-objective decision making methods to water quality management tasks optimal compromise solutions between ecological and man-made management operations will be obtained. The DSS REHSPROX was used to compute Pareto-optimal solutions of the DO balance of the Upper Spree River as a part of the River Elbe basin. ...

Missing data in environmental time series lead to some general problems in many fields of environmental research and simulation. They cause not only difficulties in process identification and parameter estimation but also misinterpretations of spatial and temporal variations of environmental indicators. Mostly, time ...

In this paper results of a water quality modelling framework for riverine shallow lakes are presented. Based on investigations of interrelations between variables of freshwater quality by advanced time series analysis methods a process model for phosphorus remobilisation from lake sediments was developed. For predicting ...

The control of water quality of freshwater ecosystems is inherently multiobjective. Mostly, scenario analyses based on simulation runs of one or more models are carried out. Some applications are known where a two stage simulation-optimisation combination help to solve water quality management problems. To control the ...

An environmental monitoring design in general and a freshwater monitoring system in special focus on important variables of an ecosystem which give a decision maker the possibility to select different types of actions from the domain of decision. In this sense, a decision model is divided into the part of the decision ...

Sustainable management decisions to control the quality of freshwater ecosystems can only be achieved by using powerful simulation tools where the functioning of ecosystems and water uses will be affected by polluted water. One of the long-term environmental problems of freshwater ecosystem management is the control of ...

In this paper results of an eutrophication modelling framework for shallow lakes are presented. Based on investigations of variables of freshwater quality by advanced time series analysis methods the process of phosphorus remobilisation from lake sediments was modeled and included into an eutrophication model. Simulation ...

Polluted water affects not only the functioning of freshwater ecosystems and various water uses, but risks human health. One of the long-term environmental problems of freshwater ecosystem management is the control of eutrophication. It is characterised by an intensive increase of dissolved nutrients in water bodies, by ...
