Environmental Monitoring System

(The Anagara river)

Object of Investigation

The project was performed as a sub-contract for the State Technical University, St. Petersburg, Russia.

The large Siberian Angara river is located at the center of a very complex industrial and agricultural area in Russia. The Environmental Inspection and Environmental Control Forces potentially were able to measure 21 different types of pollutants (chemical components) in 35 sections of the river. Also, there were objectives to regulate the pollutant concentrations by using different cleaning procedures and restriction of industrial waste activity from the river banks.

Primary Goals

 The purpose of the research was to identify pollution sources, design a pollution control and monitoring system, and estimate the pollution side-effects.


The research team was confronted with a very complex dynamic system that included hidden control activities. To separate the roles of all components and to construct a realistic model was a difficult task. Additionally, any meaningful control actions had to comply with numerous constraints and reduce undesirable side-effects.

 The Result

KET identified rules for 21 pollutants and a “dynamic simulation model” was constructed from using these rules. It was used in computer experiments for decision-making support. KET generated a map of the river to identify the optimal data collection points. On the basis of these findings, an automated environmental information system was created. Since then, the Environmental Control system designed by KET, is presently being used by the Environmental Control and Inspection Centers.


The major purpose for the research was to stabilize the environmental condition in this region. Additionally, it would help coordinate environmental protection plans for different industrial and agricultural regions. The project results were used to organize less expensive and more accurate system to measure activities and provide helpful information to the Environmental Control and Inspection Centers.

 How it was Accomplished

As in previous projects, an Information Analysis Module from the KET Tool Kit was applied to a selection of essential variables. In this case, KET was used in a more sophisticated manner considering the research of system was essentially dynamic: in correlation in changed of time. The dynamic variant from the Information Analysis Module composed a list of potential side effects to future pollution activities before the model was constructed. An Analytical Descriptor was used for the description of the crucial relationships between variables. KET Optimization Modules were applied to the final generation of control schemes, which were implemented later as parts of the Automated Environmental Control System.


The experience obtained in this research project is used to analyze various dynamic systems that are not associated with environmental problems. The same routines can be applied to projects that have risk applications such as: the insurance, investment fields, etc.

  New Feature !!

A new KET module was introduced recently to support interaction with "Mathematica 8" system.
