| Abstract | In this paper, the route prediction for a person in water was performed on the basis of a developed graph algorithm. This person drifted in water under the influence of surface currents and wind. The total drift route for the person in water was established as the route in a weighted directed graph. Vertices of this graph correspond to given points within a given basin. Additionally, the graph’s edges show possible directions of the overall human drift. The weight of the given edge describes the difference between the gradient of the edge and the total drift direction calculated on the basis of surface current field data and wind field data. An application has been created on the basis of a given algorithm which might be used to support the search for survivors in coastal areas (e.g. port basins, basins adjacent to the port, bays and sea areas) for which hydrodynamic models reliably reflect local phenomena. |

| Funding | This research outcome has been achieved under the research project No S/4/S/INM/15 financed by a subsidy from the Ministry of Science and Higher Education for statutory activities. Furthermore, the author would like to thank the Institute of Meteorology and Water Management (IMGW) for sharing the data on wind parameters for the chosen meteo stations for July 2nd 2012. The author would like to also thank the Oceanographic Institute UG (namely Marek Kowalewski, PhD) for sharing data on the surface currents’ parameters and the real experimental data for the western part of the Gulf of Gdańsk for July 2nd 2012. Moreover, the author would like to thank Krzysztof Pleskacz, PhD, Eng., for providing useful comments. The author expresses their sincere gratitude to all of the above. |
