to present all possible scenarios, the scenarios for 2018
and 2022 were limited to 16. Wind forcing has a significant influence on particle release along the Arzew coast,
according to Duran Rodrigo (2018). This force appears to
be the only one capable of generating and maintaining
the observed coastal currents. Particle trajectories change
as seasonal winds change [47, 54].
During the various hypothetical simulation scenarios,
the evaporation of ALGERIAN BLEND and ALGERIAN CONDENSATE STATOIL crude oil accounted for more than 60%
of the two-day volume reduction. The rest of the oil, on the
other hand, maintained sufficient buoyancy to remain on
the surface of the water, as demonstrated by the results of
the various simulations, because the two types of oil have
very high API (American Petroleum Institute) densities of
44.87 and 68.4, respectively, indicating that they float on
the water form a very thin film on the surface of the water,
increasing their exposure to the environment and, as a
result, weathering processes such as evaporation and dispersion. ALGERIAN CONDENSATE STATOIL exhibited higher
evaporation and natural dispersion rates during the simulations than ALGERIAN BLEND. Evaporation was also found
to increase with slickness, temperature, and wind action.
If the time to impact is greater than 24 h, the fraction
of mass stranded is small in most scenarios. As a result,
the magnitude of the environmental risk is determined
by the length of time the oil spends at sea, as confirmed
by the Nagheeby and Kolahdoozan study [46]. The dominant wind direction for the study area is southwest in the
winter, west in the autumn, and North in the summer and
spring. The movement of the oil slick confirms that the
wind is the driving force, with the slick moving south to
the center of the coastal area in winter and East to Mostaganem in autumn scenarios. During the summer and
spring, the slick only moved to the West.
The amount and direction of the oil spill at various
time intervals following the accident are critical for
determining the best response method [49]. As a result,
the system finally provides the output of the response
argument variations, the timing, and the direction of use.
The system specifies the location and quality of the skimmer and booms on behalf of the coastal management
authority in charge of responding to the accident. This
intervention system will be especially useful in waterways near sensitive areas where oil transport is dense,
such as Arzew and Bethioua. In these sensitive areas, the
responsible coastal authority must make the most accurate and timely decisions in accident response management. After recognizing the importance of modeling as
a critical tool in combating marine pollution and changing seawater quality, and after running a series of scenarios, it became clear that wherever the oil spill in the
Gulf of Arzew occurs, it will be a major disaster affecting
the environment, tourism, and the economy. Because
the depth is shallow and the currents are almost nonexistent, an accident causes quasi-significant pollution.
NOAA’s ADIOS simulation software was used to forecast
the weathering of the spilled oil (Table 5) [47].
The ADIOS model results show the different weathering rates of the spilled oil, and WebGNOME also supports
scenarios that only consider the oil weathering (similar
to the previous NOAA ADIOS model), as shown in Fig. 16.
The results of the ADIOS model showed that Evaporation began immediately after the oil was spilled into
the seawater for all 16 scenarios. About 40–45% of the
oil spill evaporated in the first hour of the spill. After
that, the evaporation rate gradually increased. It was
found that after 5 days, the evaporation rate of the
spilled quantities of the 16 scenarios varied from 74.7%
to 79.8% of the spill quantity for ALGERIAN BLEND and
85.6% to 91.4% of the spill quantity for ALGERIAN CONDENSATE STATOIL, almost half of the amount of crude
oil spilled evaporated. On the other hand, the natural
dispersion rate was slow, starting after 1 h of the spill
and reaching about 1% at the end of the simulation for
ALGERIAN BLEND and about 13% for ALGERIA CONDENSATE STATOIL (Table 6). Therefore, oil spill responders
could use this study as a reference or guide to inform
