The purpose of this paper is to show the results of the investigation of the environmental components quality (surface water, groundwater and sediments) in the winter – spring 2008 campaigns. The systemic characterization of the physico-chemical and biological environment is realized by development of investigation program of the water body represented by the Suceava River and main affluent: Pozen, Solonet and Salcea streams. Based on the investigations performed, the time and space evolution of the main stock-up (surface water and sediment) and cycling (phytoplankton, zooplankton and macrozoobenthos components) reservoirs characteristics of the aquatic ecosystems in the analysed area are shown. Also, investigations of the underground water aim to underline connections between its quality and surface water quality. Therefore, accumulation of sediments of the chemical quality indicators was follow-up. The investigations results were integrated in the mathematical model using Spline functions to mark out evolution and transportation: oxygen regime (as COD and BOD) and nutrients (ammonium, nitrates, nitrites, total nitrogen, total phosphorus) for the Suceava river; salt (TDS, chlorides, sulfates, sodium) for the Solonet stream. The solutions of the equations can be used in modelling and estimations predictions of water river parameters for established period of time.
