ADVANCED HYDROINFORMATIC TOOLS FOR MODELLING OF ASSOCIATED PROCESSES WITH WATER QUALITY
Erika BEILICCI, Robert BEILICCI
ABSTRACT. – Water quality expresses the suitability of water to sustain various uses or processes: water for drink, food production, irrigation, animal husbandry, fishermen, recreation etc. Each use will have certain requirements for the physical, chemical or biological characteristics of water. The quality and composition of surface and underground waters is determined by natural factors (geological, topographical, meteorological, hydrological and biological characteristics of catchment) and by human activity (industrial wastes, sewage, runoff from farmland, cities, factory effluents, different hydrotechnical arrangements etc.). The evolution of water quality is also determined by the processes that take place in water bodies: chemical (neutralization, oxidation, reduction, flocculation, precipitation, adsorption, absorption, photochemical decomposition), physical (dilution, mixing, diffusion, sedimentation, coagulation, dissolution of oxygen, release of gases into the air, also influenced by solar radiation IR and UV, water temperature), biological (by its own biocenosis that competes with foreign elements, either directly, by lytic action (bacteriophages), filtration (shells), consumption (by protozoa) or the secretion of toxic substances for intruders (actinomycetes) and biochemicals (within the cycles of nitrogen, sulfur and carbon, based on the activity of specific microorganisms)). In this context, modeling the evolution of water quality is of particular importance for efficient water management. For the best possible forecast of water quality, the use of advanced hydroinformatic tools, such as the MIKEby DHI (Danish Hydraulic Institute) software package, is needed. The paper presents the possibility of using these tools and conducts a case study on a sector of the Bega River, downstream of Timisoara.
