“…In order to determine the numerical fluxes F (Eq. (7a, 7b)) by the cell edges in the advection equation, the second-order Lax-Wendroff scheme was used (Potter 1980). In the case of the dispersion part of the transport equation, the central differential schemes were used.…”

“…Over the past 20 years, work has been carried out on modeling hydrodynamics and pollution migration in the area of the southern Baltic and the Gulf of Gdansk (Kowalewski 2001;Jedrasik 2005;Kowalewska-Kalkowska et al 2007;Pyrchla et al 2016).The emerging models are mainly adaptation of ocean models, and their scale in the area of the Bay of Puck is insufficient for modeling on a local scale. For this reason a numerical model of part of the Gulf of Gdansk was made in order to analyze the impact of pollution from agricultural areas of the Puck District (Fig.…”

The paper presents the analysis results of the impact of pollution discharged by surface waters on the quality of the Puck Bay waters. Puck Bay is part of the Gulf of Gdansk and belongs to the Baltic Sea. The analysis was carried out using mathematical modeling. A numerical model of part of the Gulf of Gdansk was achieved, taking into account the current bathymetry and the shoreline shape. The pollutants inflow was assumed point-by-point at the mouth of the main watercourses: Plutnica, Gizdepka, Bladzikowski Creek and the Reda River. The hydrodynamic conditions in the Bay were adopted for several scenarios regarding wind speed and direction. In order to determine the velocity distribution, the Ekman model-dedicated to shallow coastal waters-was used. The spread of pollutants in the Bay's waters was determined by solving a two-dimensional, partial differential, advection-dispersion equation describing the migration of a non-degradable dissolved matter. The finite volume method was used for the solution. As a result, the extent of pollution in the Puck Bay area was obtained in relation to Natura 2000-the European Union's protected areas. Visible is the necessity of integrating these conclusions into measure aiming at the mitigation of eutrophic processes in the Baltic Sea. The results of this research may be extended to serve other bay regions adjacent to similar substantial agricultural activities.

“…The map allows for efficient identification of the landowner or those responsible for any irregularities, and for the reporting to the relevant city services. 17 In Lublin and Poznań, due to the lower intensity of tourist and investment traffic compared with the above-mentioned cities, GIS is characterized by classical layers, without individual solutions. However, it is worth noting that the number of tabs, in particular thematic layers characteristic of the city's specificity, has been enhanced.…”

Technical and technological progress in the 21st century, especially emerging geographic information system (GIS) technology, offers new and unprecedented opportunities to counteract the impact of crisis situations and emergencies. Computerization and development of GIS enabled the digital visualization of space for interactive analysis of multiple data in the form of models or simulations. Additionally, computerization, which gives rise to a new quality of database management, requires continuous modernization of computer hardware and software. This study examines selected examples of the implications and impact of the GIS commonly used in Poland.

“…That data are often generated by numerical models. The access to such data might be obtained by, e.g., the Geographic Information System such as the Maritime Network-Centric Geographic Information System Gulf of Gdansk [16]. Sometimes, some relations between the wind and wind-driven currents are established [20].…”

This study focuses on the investigation of available surface currents and wind parameters for employing them in order to predict the survivor movement in the Szczecin Lagoon waters. For this purpose, the surface currents and wind parameters were generated by selected numerical models and the wind parameters were also measured with the telemetry devices. In this paper, the PM3D hydrodynamic model and the NEMS, ECMWF, GFS weather forecast models have been investigated. The measurements of the wind parameters, recorded at the Brama Torowa I and Trzebież stations, were also analyzed. As part of the research, an expert method was used to evaluate the surface currents parameters. In turn, the method based on comparing the forecasted wind parameters with the measured wind parameters was applied in order to assess uncertainties of these parameters. The comparative analyses of the data on the surface currents and wind parameters have been done and probabilistic models for uncertainties of these forecasted parameters have been formulated. Additionally, relations between the surface currents speeds and the wind speeds, in the case when their directions were consistent, have been also discovered. http://www.transnav.eu the International Journal on Marine Navigation and Safety of Sea Transportation Volume 12 Number 4
