Creation of Computer Simulation Model for Ecological Consequences Prognosis of Toxic Chemicals Discharge from Sunken on Baltic Sea Bottom Weapons"

This study summarises all the accessible data on old German chemical weapons dumped in the Baltic Sea. Mr. Goncharov formulated a concept of ecological impact evaluation of chemical warfare agents (CWA) on the marine environment and structured a simulation model adapted to the specific character of the hydrological condition and hydrobiological subjects of the Bornholm Deep. The mathematical model he has created describes the spreading of contaminants by currents and turbulence in the near bottom boundary layer. Parameters of CWA discharge through corrosion of canisters were given for various kinds of bottom sediments with allowance for current velocity. He created a method for integral estimations and a computer simulation model and completed a forecast for CWA "Mustard", which showed that in normal hydrometeorological conditions there are local toxic plumes drifting along the bottom for a distance of up to several kilometres. With storm winds the toxic plumes from separate canisters interflow and lengthen and can reach fishery areas near Bornholm Island. When salt water from the North Sea flows in, the length of toxic zones can increase up to and over 100 kilometres and toxic water masses can spread into the northern Baltic. On this basis, Mr. Goncharov drew up recommendations to reduce dangers for human ecology and proposed the creation of a special system for the forecasting and remote sensing of the environmental conditions of CWA burial places.

New Prosperity for Rural Regions

The project deals with problems of marginal rural regions in the period of transformation in Slovenia and the Czech Republic. The course of the transformation, its impact, related border problems and environmental aspects were studied in seven model regions of the two countries, using geographical, cartographic, sociological, historical and remote-sensing methods. The opinions of both the local populations and the local authorities were also taken into account. The most important problems observed included the deepening of marginality, the worsening situation in the labour market, structural demographic degradation of the most marginal settlements and a lack of development programmes. In the Czech Republic the state had no effective regional policy up to the time of the research. Possibilities for future prosperity include exploitation of human and other local resources, the elaboration of local and regional programmes capable of gaining financial support and the utilisation of tranquility and the positive environmental situation. It is the local people who usually represent the main wealth of marginal regions and care for them is the task of the local authorities.
