We calculated the spatially variable decease coefficient of E. coli from the extrapolated measurement data on environmental parameters in accordance with Mancini's equation for bacteria stemming from the Rižana River and entering into the computational domain % the eastern part of the Koper Bay. Using pre-computed circulation data and the modified particle-tracking model Nafta3D we performed two-day simulations of an instantaneous and a continuous release from a single source. We analyzed locations of two particle types: free E. coli (ECF) and E. coli bound to suspended solids (ECA). We then analyzed the ECA and ECF activity decrease with a newly developed decease model, applying a first-order kinetics equation. In the given conditions a vast majority of ECA remained in the second basin of the Port of Koper and sank to the bottom layers. The decease time of 90% of the ECA (T90) was about 48 hours. The ECF remained closer to the surface; they moved more quickly and for the most part abandoned the second basin. The determined T90 was 6 and 10 hours in instantaneous and continuous release, respectively</dc:description><dc:description xml:lang="sl">Obravnavamo modeliranje transporta in odmiranja bakterij Escherichia coli v morju. Iz ekstrapoliranih meritev okoljskih parametrov smo po Mancinijevi enačbi izračunali krajevno spremenljivi koeficient umrljivosti E. coli, ki vtekajo z Rižano v računsko območje, vzhodni del Koprskega zaliva. S predhodno izračunanimi hitrostnimi polji smo z modificiranim modelom sledenja delcev Nafta3D opravili dvodnevne simulacije izpusta delcev iz enega izvora in analizirali lokacije dveh vrst delcev % prostih bakterij (ECF) in bakterij, pričvrščenih na suspendirane delce (ECA). Nato smo po razpadni enačbi prvega reda in z izračunanimi koeficienti umrljivosti analizirali zmanjševanje aktivnosti ECA in ECF z novim modelom odmiranja E. coli. V danih razmerah velika večina ECA v 48 urah ostane na območju drugega bazena Luke Koper in potone v sloje vode ob dnu. Čas, ko odmre 90 % ECA (T90), znaša približno 48 ur. ECF se v manjših globinah premikajo hitreje in drugi bazen Luke Koper pretežno zapustijo. T90 je pri hipnem izpustu enak 6 ur, pri kontinuirnem pa se podaljša na 10 ur, približno za čas izpusta</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-BE6UN314"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-BE6UN314" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-BE6UN314/17821bf7-8c2e-49c8-a6b9-41df9429002e/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by-nc-sa/4.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za gradbeništvo in geodezijo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-BE6UN314/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-BE6UN314" /></ore:Aggregation></rdf:RDF>
