The common problem for numerical modeling of hydrodynamic processes is the accordance of the model results with the in-situ collected data. This paper presents validation methods of model results by in-situ measurements and Earth observation products, analyzing the distribution maps provided by the ESA and NASA services. In term of spatial and temporal resolution the observation data can be improve by using short range remote sensing technics such as UAVs/aerial technics. Despite the lack of in situ data in the western Black Sea basin several data sources were accessed in order to compare de model results against the data collected in the field. In situ date were also used to provide support for observation data calibration/validation, in the area of interest.
