The ADRICOSM project was launched in October 2001, and ended in March 2005, with the main objective of demonstrating the feasibility of a near real time operational marine monitoring and forecasting system at the shelf and coastal scales, with connections to river basin runoff and coastal town sewer systems. The basic system consisted of an efficient network for the collection of marine data such as in situ temperature and salinity profiles and satellite sea surface temperature, a regional (AREG) and shelf scale modeling system, a data assimilation system and finally a coastal scale modeling system. Every week AREG releases 7 day marine forecasts at 5 km horizontal scales, which are used to nest other hydrodynamic models toward the coastal scale. Two shelf models (ASHELF-1 and ASHELF-2) at a 1.5 km horizontal scale were nested in AREG in order to simulate (and in the future to forecast) shelf scale oceanographic features. Another important aspect of ADRICOSM was the integration of the Cetina river (Croatia) and urban sewage monitoring/ modeling (Split, Croatia) systems with the shelf marine model. This integrated model system was used to simulate the dispersion of sewer discharges from the urban area in the coastal waters for water management performance studies. ADRICOSM is one of the first integrated land and marine waters operational oceanographic systems able to meet the urgent needs for reliable integrated coastal forecasts for the effective management of marine areas.Projekt ADRICOSM započeo je u listopadu 2001. i završio u ožujku 2005. godine. Glavni je cilj projekta bio pokazati mogućnosti operacionalizacije monitoringa i prognoze u skoro realnom vremenu na šelfu te u obalnim područjima koja su povezana s riječnim bazenima i gradskim otpadnim vodama. Sustav je bio opremljen efikasnom mrežom sakupljanja podataka izmjerenih u moru kao što su profili temperature i saliniteta te satelitske površinske temperature mora, regionalnim jadranskim modelom (AREG) i modelom na skali šelfa, sustavom asimilacije podataka te konačno, obalnim modelom. Svaki tjedan AREG je izrađivao 7-dnevnu oceanografsku prognozu na horizontalnoj skali od 5 km koja je upotrebljavana za gniježđenje drugih hidrodinamičkih modela duž obale. Dva modela na šelfu (ASHELF-1 i ASHELF-2) horizontalne rezolucije od 1.5 km ugniježđeni su u jadranski AREG model s ciljem simuliranja (te u budućnosti i prognoziranja) oceanografskih osobina šelfa. Drugi važan aspekt ADRICOSM projekta bio je integracija monitoringa i modeliranja dotoka rijekom Cetinom i sustavom otpadnih voda s oceanografskim modelom šelfa. Ovaj je integracijski sustav upotrebljen za simuliranje disperzije urbanih otpadnih voda u obalnom području. Projekt ADRICOSM je jedan od prvih integracijskih sustava kojim se za potrebe operativne oceanografije i prognoze ujedinjuju obalne vode s dotocima s kopna s ciljem efikasnog upravljanja obalnim područjima
