Vertical Dispersion Process of Oil Spills Hanifeh Imanian*, Morteza Kolahdoozan, Amir Reza Zarrati Department of Civil and Environmental Engineering Amirkabir University of Technology Tehran, Iran E-mail:
[email protected] Abstract—Oil spills in marine waters undergoes different processes including advection, surface spreading, evaporation, emulsion, dissolution, bio-degradation, photo-oxidation, hydrolysis and natural dispersion in the water column. Due to environmental effect on marine ecosystem and determining spilled oil lifetime, vertical dispersion has a great importance. Despite, the complexity of the process not much attention has been paid to this phenomenon till now. In the present article, analyses of experimental data cited in the literature have been carried out and variations of oil concentration distribution in water bodies have been investigated. According to the above analysis it can be concluded that oil concentration distributions follow a nearly parabolic curve both in time and space.
addition, water emulate in oil, oil dispersed in the sea depth and heavier elements settle on the sea bed. Besides, photochemical and biological changes happen slowly. Consequently, the oil penetrates into coastal, estuaries and living areas and causes a lot of damages [4]. For the management of sea area, prevention of the pollutants penetration, control of its spreading and removal of oil pollutants, it is required to identify the transport and fate processes of oil. Dissemination of oil spill in water body is carried out by physical, chemical and biological processes which depend on the oil and sea properties. These processes can be classified into three branches: (1) transport, (2) fate, and (3) shoreline or ice interaction (Fig. 1) [5].

INTRODUCTION
A great deal of fossil fuels is acquired from the reservoirs in the sea, transferred through waterways and may be exposed to the environment [1]. Oil dispersion in water bodies is too harmful and causes long lasting serious damages to the environment. One liter of oil can pollute up to 10’000 liter of water [2]. Owing to such a danger, attentions have been focused on the destructive effects of dispersing oil and scientific investigation in this field has a great importance. One of marine environments which are at high risk is Persian Gulf. Two important events of oil pollutants happened in this area only at the end of 20th century. About 1.45 million barrels of oil spilled in Kuwait coasts in 1991 and 600 thousand barrels spilled in Iranian coastal zones due to the explosion of Nowrouz oil fields in 1983 [3]. Oil dispersion in marine environments can be studied in two parts: (1) oil dispersion on sea surface which occurs due to the accidents of oil transferring ships or crashing of oil storage tankers, and (2) oil dispersion from the sea bed rising to the surface that can be due to cracks in oil transferring pipes on the sea bed, explosions of subsurface oil extraction wells, or sinking of oil tankers at sea bottom. In the event of spilling oil on water surface, the oil will be distributed on the sea surface and spreads on the water as a thin layer. Sea currents and wind are the main causes of moving this layer and unbalance between gravity forces, viscosity, surface tension and oil- water interfacial tensions affect on the movement direction. Light components of oil evaporate and soluble parts solve in water, therefore the layer becomes thinner. In
VERTICAL DISPERSION PROCESS OF OIL SPILL
Natural dispersion of oil is surface oil breakage, its conversion to sub-surface oil droplets, and transferring and dispersing these droplets at the water column [6, 7]. Oil droplets size distribution, stability of dispersed oil in water column and re-entrainment to the surface should be considered in dispersion process. Dispersion moves oil from water surface. Natural dispersion is just mixing oil droplets with water and entering into the sea body. Hence, the oil droplets properties are not different from the spilled oil. Dispersed oil drops in water column will mostly expose to fate processes and their chemical properties will be changed over the time. Oil Spill Processes

Physical, chemical and biological oil spill processes
In addition to the sea conditions, natural dispersion rate depends on the oil characteristics including: density, surface tension and viscosity. Dispersion usually increases dissolution and bio-degradation and decreases evaporation. Wave breakage through shear velocity has an important role in its spread in turbulent currents. Spilled oil dispersion, scattering and drowning of surface oil slick and splitting in droplets depends on the flow turbulence structure. Turbulence has a great role in vertical mixing of oil drops in water column [6, 8, 9]. The spilled oil in marine environments is exposed to the natural dispersion in water column by waves. On the other hand most of contamination removal methods just eliminate the surface oil or displace it from sea surface to water column and/ or sea bed. Hence, calculating the dispersed oil is required for estimating spilled oil lifetime [10] not only on the surface, but also in water body. Dispersing an oil spill can reduce the environmental impact if the water volume is large enough for effective dilution. In most cases, rapidly oil dispersing into the water column at open sea will be cheaper than mechanical shoreline clean-up from an economic standpoint [9]. Therefore, one of the important issues in the field of oil slick transport is to estimate the amount of oil which enters into the water body due to the dispersion processes. III.
dispersion rate is as a function of energy dissipation due to wave breakage at water surface, oil type and fraction of sea surface covered with oil. Also, entrainment rate of oil droplets per unit area equals to multiplication of oil droplet size, energy dissipation rate per unit surface, fraction of sea surface covered by oil and a coefficient depending on the oil type [12]. The achieved dispersion rate is for each event of wave breakage. For obtaining general entrainment rate, it should be multiplied to a fraction of sea surface which is subjected to wave action. Moreover, it is recommended to integrate the answer on the smallest size of oil drops up to the largest one. Since components of the last relationship can be easily calculated, this method is widely used in research and commercial models. From comparing and analyzing empirical relationships for oil dispersion rate into water column, especially Delvigne and Sweeney (1988) or Mackey et al. (1980) formulas, it can be concluded that most of relationships have only considered the surface dispersion rate. In other word, one just can estimate how much oil is reduced from the surface slick and is entered into water column. Until now no relationship can predict oil concentration in water column as a function of space and time. IV.
OIL SPILL EXPERIMENTS AND RESULTS ANALYSIS
To obtain the variation of oil concentration in the water column over the time, a number of experiments have been carried out and reported in the literature. Page et al. (2000) performed an experiment to study efficiency of dispersants in surf zone. Some other tests were designed by Li et al. (2008, 2009) for evaluating effect of chemical dispersants in a wavy channel [8, 9, 13]. Data obtained through experiments can relate oil concentration in water column (c) to time (t), water depth (h) and distance from the spilling location (d). According to Page et al. (2000), measurements were collected at two points (just below water surface near beach and depth 30 cm far away from beach) in four time section (midday, 1, 4 and 10 days after spilling). From experimental results it can be concluded that at both sections, oil concentration decreases over the time (Fig. 2). According to Li et al. (2008), measurements were collected at 10 points (at distances of 1.5 and 4 m from spilling location, in depths of 5, 20, 40, 60 and 110 cm from water surface) at 10, 30 and 60 minutes after oil spilling.
OIL DISPERSION RELATIONSHIPS
A number of studies have been performed for modeling oil spill and its components in the past few years. First researchers studied the relationship between dispersion and turbulent energy in 1950s [11]. They found that oil viscosity and oil- water interfacial tension are the most important parameters in this process. Later, they attributed dispersion to the turbulent energy domain. A great number of oil spill models calculate dispersion by simple relations which obtained originally based on experimental measurements. In these types of relationships the oil type, sea condition, wind speed and time are the important parameters in the dispersion process. One of the empirical relationships which is used by many researchers in their numerical model over a long period of time is introduced by Mackey et al. (1980). According to their hypothesis, the oil slick divided into thin and thick parts. The dispersion rate was suggested as a multiplication of sea surface (which is exposed to dispersion) into oil droplets volume (which their size are small enough to be dispersed in water column) [10]. Afterward, Delvigne and Sweeney (1988) conducted some laboratory experiments for relating oil dispersion rate, dispersed oil droplet size and penetration depth of oil droplets in the water column. They recognized dissipation of turbulent energy due to wave breakage as the most important parameter in the oil dispersion. The obtained relationship introduces dispersion rate at the unit surface for each group of oil droplet size. In his relationship the 2

Probably, during maximum oil dispersion time, oil slick moves on water surface and reaches above water column of that section. In small scale test of Li et al. (2008), from Fig. 3 it can be concluded that maximum oil dispersion time is more than the time of the experiment, i.e. 60 minutes. This is since at all points, oil concentration increased with time. On the other hand, in large scale experiment of Page et al. (2000), from Fig. 2 it can be seen that maximum oil dispersion time is less than time of this experiment, i.e. 12 hours, and as a result oil concentration decreased with time. This finding is confirmed with Li et al. (2009) oil concentration data at a point in a depth of 75 cm from water surface and 10 m from the spilling position. Fig. 4 shows that concentration has first increased with time; and then had a decreasing trend. It means that at each point, immediately after spilling time, oil concentration increases until the maximum oil dispersion rate is achieved and then concentration decreases. Besides, oil concentration increases at any point away from spilling location, for both breaking wave type, at all times and depths in small scale test of Li et al. (2008). The distribution curve of oil concentration can be considered as parabolic, ascending first and then descending. These hypothetical parabolic curves of oil concentration distribution could be seen in Fig. 5.

Tests were performed for both spilling and plunging breaking wave. Fig. 3 shows that oil concentration increases for two wave breaking types with time, for different sections and depths. Since experimental results of oil concentration changes do not confirm each other, it is necessary to analyze the results to achieve a general trend for oil concentration distribution. Looking into these tests setups, the first test can be classified as “large scale” and the second one as “small scale”. In small scale test of Li et al. (2008), oil concentration increased with time, while in large scale model of Page et al. (2000), it decreased. From available data of Page et al. (2000) and Li et al. (2008) experiments, it can be seen that oil concentration increases till a certain time and then decreases. This is due to oil transport by wave action to some distances from its source. Later, combination of flow and wave cause dissipation of oil in that location and oil concentration decreases. It seems that the time at which oil concentration is maximum (maximum oil dispersion time) is a function of oil advection in water body as well as oil slick motion on water surface.

This finding is approved with data of Li et al. (2009), in which oil concentration at 6 points in distances of 2, 6 and 10 m from the spilling location at depths of 75 and 140 cm has been reported. It can be concluded from Fig. 6 that the curve of concentration distribution is also parabolic. In other words, oil concentration has been increased initially and then decreased. Moreover, the considered parabolic curve is confirmed with measurements of oil concentration in water depth as a function of distance from spilling location according to Li et al. (2009) experiments (Fig. 7). It should also be noted that considering velocity of flow and oil dispersion in water, selected sampling locations and time sections in oil spill tests should be accurately selected. Experiments should be designed so that the sampling period covers both ascending and descending parts of concentration curves.

In this article, vertical dispersion phenomenon and its position among oil spill process is described. Some applicable empirical relations for calculating oil dispersion in water column were reviewed. In numerical models, oil dispersion rate has been calculated by experimental relationships and less attention is paid to oil concentration distribution in water column as a function of space and time. Therefore, in future models, it is required to focus on oil distribution trend in water column. Oil dispersion experiments have been studied and laboratory results were analyzed. After comparing results of different tests and observing their non-conformity, a hypothesis was presented for describing the trend of oil concentration changes in water column. Based on this hypothesis, oil concentration distribution is a parabolic curve in place and time. It means at any point in water body, after the spilling, oil concentration increases until a maximum dispersion time and after it, concentration will decrease. Also away from spilling location, oil concentration first increased and then decreased. These hypotheses have been confirmed by other test results.
