	abstract = {The objective of this paper is to present a background for a concept of situation-dependent adjustment of environmental regulations for the prevention of ship-generated sewage pollution. Unlike the standard rules based only on a constant distance from the nearest land that routinely disregard the effect of drift caused by local surface currents, tidal streams, or winds, we consider taking into account the situational dependence in addition. This includes the available hydrometeorological data on the seawater flow, the initial position and time of disposal, and ultimately, sea state, the physical and biochemical properties of the substances (sewage, wastewater) discharged overboard. Computing the approximate dynamics of drifted sewage yields estimated information on the prohibited (permitted) zones of discharge and the boundary subareas of the predicted distribution or the maximum (minimum) concentrations of contaminants, respectively. This can be further applied to the innovative decision support systems aimed at preventing local pollution, involving stakeholders on both sides: ship masters and shore services on marine environment protection, as well as to developing local legislation. In order to justify the proposed approach and to emphasize the relevance of situational dependence concerning the natural motions of sea water bodies, our study is illustrated with some examples based on real-world data including various drift effects.},
