Abstract

As a consequence of the hydrologic features of the Danube, the variation in concentration of a number of conventional water quality components is of tendentious character. The statistical evaluation of the data series available enables us to decrease or increase the frequency of sampling per component. The latter statement can primarily be understood for the micropollutants. It was found from the research results that on the Hungarian Danube reach the oil derivates, certain heavy metals as well as in the winter season phenols and ammonia caused problems. Of these pollutants, oils and heavy metals can only be characterized by the simultaneous examination of suspended solids and bottom sediments. Recognized the essential transverse inequality in water quality parameters, it was an important task to develop a proper and representative program for sampling. For this reason the two dimensional mathematical dispersion model has also been used elaborated here previously. The model contains depth averages considering the river geometry and based on regular hydrographical data recording. With the help thereof investigation can easily be performed on several hundred kilometer long river stretches. The model can further be developed without any difficulty to a two dimensional BOD or COD model. However, from the above studies the conclusion could be drawn that in the future modelling activities should principally be directed to the transport of bio-resistant substances.
