Hydrodynamics due to wind, tidal forcing and river inflow momentum can be simulated, and stratified conditions can be taken into account. Data on temperature and salinity fields and winds in the Gulf of Trieste, Soča River discharges, suspended sediment concentractions and temperature were collected and interpreted. These data, together with measurements of mercury concentrations in the water, suspended sediment, bottom sediment and pore waters in the Soča river and the Gulf of Trieste are used as input for the model. A scenario for long-term simulations on the basis of seasonally averaged parameters and a few shorter inserts of strong wind and high discharges of the Soča river was developed as a substitute for simulations based on annual averaged input data. Measurements and observation data from 1995-1997 were applied to verify and calibrate the PCFLOW3D model. Although some complex mercury transformation processes are not well known and were therefore not taken into account in the simulations, an acceptable qualitative agreement of results and measurements was achieved. Whenever a quantitative comparison was possible, an accordance of measured and computed results within a factor of two was attained"},{"@xml:lang":"sl","#text":"Za dolgotrajno simulacijo transporta in disperzije živega srebra v raztopljeni in na delce vezani obliki smo dopolnili obstoječi tridimenzionalni matematični model PCFLOW3D, s katerim je mogoče upoštevati gibanje vode zaradi vpliva vetra, plimovanja in gibalne količine rek, ki vtekajo v zaliv ter stratifikacijo. Zbrani in prikazani so podatki o temperaturnih in slanostnih razmerah ter vetru na območju Tržaškega zaliva. Te skupaj s podatki o pretoku, temperaturi ter vsebnosti živega srebra v vodi in na delcih lebdečih plavin, ki dotekajo v zaliv s Sočo, predstavljajo vhodne podatke modela. Z izdelanim scenarijem za dolgotrajne simulacije, ki temelji na sezonsko povprečnih vrednostih posameznih parametrov in z dodatnimi krajšimi vložki močnega vetra in visokih pretokov Soče smo nadomestili dosedanji način simulacij s povprečnimi letnimi vrednostmi. Za verifikacijo in umerjanje izpopolnjenega modela smo uporabili meritve in opazovanja iz let 1995-1997. Čeprav nekateri kompleksni procesi pretvorb živega srebra še niso povsem raziskani in jih zato ni bilo mogoče upoštevati pri simulacijah, je doseženo kvalitativno dobro ujemanje rezultatov in meritev.
