Description

[Technical Field]

[0001] The present invention relates to a method for determining the diffusion characteristics of various hazardous and noxious substances (HNS) spilled into the ocean. More specifically, in general, in order to assess the environmental impact of HNS spills or discharges into the ocean, it is first necessary to simulate the diffusion of HNS in the ocean and accurately determine the diffusion characteristics of HNS in the ocean. However, to achieve this, it is necessary to spray HNS in the actual ocean and observe the diffusion process. However, due to the danger of HNS, it is impossible to spray HNS in the actual ocean, making it difficult to accurately determine the diffusion characteristics. To solve this problem, the present invention relates to a method for determining the diffusion characteristics of hazardous and noxious substances at sea using a simulator, which is configured to determine the diffusion characteristics of HNS in the ocean using a simulator instead of spraying HNS in the ocean.

[0002] Furthermore, in order to solve the problem of the prior art HNS diffusion characteristic estimation method, which was difficult to grasp accurately because it was not possible to actually spray HNS in the ocean and perform measurements as described above, the present invention classifies HNS into 12 groups based on their physicochemical properties, and performs processing to calculate the floating, dissolving, and sinking behavior characteristics of HNS in the ocean based on the results of observing and analyzing the diffusion characteristics of HNS using simulants for each of the three behavioral characteristics of floating, dissolving, and sinking.As a result, the present invention relates to a method for estimating the diffusion characteristics of hazardous and harmful substances at sea using simulants, which is configured to more accurately grasp the diffusion characteristics of HNS without the need to actually spray HNS in the ocean and perform measurements. [Background technology]

[0003] In recent years, as environmental issues have come to the forefront of global attention, there has also been growing interest in hazardous and noxious substances (HNS), which are discharged or spilled into the ocean and have various adverse effects on the marine environment.

[0004] In response to this, various technologies have been proposed to enable rapid and effective response by predicting the danger radius of diffusion of hazardous and harmful substances in the marine environment or by detecting hazardous and harmful substances and determining their flow path, as shown in Korean Patent Registration No. 10-1740720, "Device and method for predicting diffusion of hazardous and harmful substances," and Korean Patent Registration No. 10-1751020, "Method and device for continuous detection of hazardous and harmful substances based on multi-satellites." However, the above-mentioned conventional technologies have the following limitations.

[0005] More specifically, there are currently 799 types of hazardous and harmful substances (HNS) designated under the Marine Environment Management Act. In order to assess the impact on the marine environment if these HNS are leaked or discharged into the ocean, it is essential to simulate and predict the diffusion of HNS in the ocean. To do this, it is necessary to accurately understand the diffusion characteristics of HNS in the ocean.

[0006] In order to accurately grasp the diffusion characteristics of HNS in the ocean, the most accurate results can be obtained by actually spraying HNS in the ocean and observing its diffusion process. However, there is a problem in that spraying HNS in the ocean is not possible under current law due to the danger posed by HNS.

[0007] Therefore, in order to solve this problem, it is necessary to obtain measurement results that are equivalent to or similar to the actual results without spraying HNS into the ocean, but the above-mentioned conventional technology has the limitation that it does not disclose such technical details.

[0008] Therefore, in order to overcome the limitations of the prior art as described above, it would be desirable to propose a method for estimating the diffusion characteristics of hazardous and harmful substances at sea using a new type of simulator that is designed to more accurately grasp the diffusion characteristics of HNS, for example, by using a simulator instead of spraying HNS into the ocean.However, at present, no device or method that meets all of these requirements has been proposed.

DETAILED DESCRIPTION OF THE INVENTION

[0024] Hereinafter, specific examples of the method for estimating the diffusion characteristics of hazardous and harmful substances at sea using a simulator according to the present invention will be described with reference to the accompanying drawings.

[0025] It should be noted that the content described below is merely one embodiment for carrying out the present invention, and that the present invention is not limited to the content of the embodiment described below.

[0026] In addition, please note that in the following description of the embodiments of the present invention, detailed descriptions of parts that are identical or similar to the content of the prior art, or parts that are deemed to be easily understandable and implementable by those skilled in the art, have been omitted for the sake of brevity.

[0027] Next, the specific details of the method for estimating the diffusion characteristics of hazardous and harmful substances at sea using a simulator according to the present invention will be described with reference to the drawings.

[0028] More specifically, in the past, in order to evaluate the impact of various hazardous and noxious substances (HNS) that have been released into the ocean on the marine environment, it was generally necessary to accurately understand the diffusion characteristics of HNS in the ocean. However, in order to understand the diffusion characteristics of such HNS, it was not possible to spray HNS in the actual ocean and simulate the diffusion process, and there was a limitation in that it was difficult to accurately understand the diffusion characteristics based on actual observations.

[0029] In order to solve the above problems, the present invention proposes a method for estimating the diffusion characteristics of hazardous and harmful substances at sea using a simulator that is designed to grasp the diffusion characteristics of HNS in a manner that is close to reality, instead of spraying HNS in the ocean.

[0030] To achieve this, as will be described later, the present invention classifies HNS into 12 groups based on their physicochemical properties, and observes and analyzes the diffusion characteristics of HNS using simulants for each of the three behavioral characteristics of floating, dissolving, and sinking. Based on the results of this analysis, the drift characteristics, horizontal diffusion characteristics, vertical behavior characteristics, and vertical mixing characteristics of HNS on the ocean surface are calculated, and the calculation results are combined to estimate the floating, dissolving, and sinking behavior characteristics of HNS. This makes it possible to grasp the diffusion characteristics of HNS relatively accurately, without the need to actually spray HNS in the ocean and perform measurements.

[0031] More specifically, referring to FIG. 1, FIG. 1 is a diagram showing an example of HNS classification applied to a method for estimating the diffusion characteristics of hazardous and harmful substances at sea using a simulator according to an embodiment of the present invention, organized in the form of a table.

[0032] As shown in Figure 1, in this invention, based on the physicochemical properties of HNS, gaseous HNS is classified into evaporation (G) and evaporation-dissolution (GD), liquid HNS is classified into evaporation (E), dissolution-evaporation (ED), floating-evaporation (FE), floating-evaporation-dissolution (FED), floating (F), floating-dissolution (FD), dissolution-evaporation (DE), dissolution (D), settling-dissolution (SD), and settling (S), and solid HNS is classified into floating-dissolution (FD), dissolution-evaporation (DE), dissolution (D), settling-dissolution (SD), and settling (S). Of the 12 classified HNS behavioral properties, a method for observing and analyzing three of them, floating, dissolution, and settling, using a simulant was proposed.

[0033] First, regarding the floating behavior characteristics, in order to estimate the floating behavior characteristics of HNS, it is necessary to understand the drifting characteristics and horizontal diffusion characteristics on the ocean surface.To achieve this, in this invention, a floating HNS simulant in the form of a vinyl membrane was allowed to drift on the ocean surface, and its movement path was tracked, and drifting characteristics such as drift speed and direction were determined from the movement time and movement distance.

[0034] Here, the drift velocity can be calculated using the following equation (1).

[0035]

number

[0036] In addition, to investigate horizontal diffusion characteristics, three or more floating HNS simulants were allowed to drift on the ocean surface, and their movement paths were tracked. Through simultaneous position analysis of the movement paths of each simulant, diffusion characteristics such as fluctuations in the diffusion area and diffusion range at each time were identified.

[0037] Furthermore, the diffusion area from the movement paths of multiple simulants starting from the same point can be calculated as the variance of the distance between the simulants, as shown in the following (Equation 2).

[0038]

number

[0039] In (Equation 2), N is the number of simulators, xi and yi are the displacements of the i-th simulator, respectively. Shows the movement path.

[0040] Next, regarding the dissolution behavior characteristics, it is necessary to understand the drift characteristics, horizontal diffusion characteristics, vertical behavior characteristics, and vertical mixing characteristics in ocean water.To achieve this, first, regarding the drift characteristics and horizontal diffusion characteristics in ocean water, an underwater HNS simulant is released into the water depth to be analyzed, and its movement path is tracked, and the drift characteristics and horizontal diffusion characteristics in ocean water can be understood in the same way as when calculating the drift characteristics and horizontal diffusion characteristics on the ocean surface as described above.

[0041] In addition, the vertical behavior characteristics in ocean water are measured by dropping two or more underwater HNS simulants into two or more water depths, tracking their movement paths, and calculating the movement speed as shown in the following equation (3). This can be calculated using the following equation:

[0042]

number

[0043] In (Equation 3), ω is the vertical velocity, δz is the depth difference of the simulated body, and u and v are The flow velocities in the x and y directions are shown.

[0044] In addition, the vertical mixing characteristics in ocean water can be calculated by dropping an underwater HNS simulant into two or more water depths (z1, z2), tracking its movement path, and calculating the movement speed as shown in the following (Equation 4). It is possible.

[0045]

number

[0046] In (Equation 4), k is the vertical diffusion coefficient, Uz1 and Uz2 are the transport velocities at z1 and z2. and δz indicates the difference between z1 and z2.

[0047] Next, regarding the sedimentation behavior characteristics, it is necessary to understand the vertical behavior characteristics in ocean water. In this case, the characteristics understood in the dissolution behavior characteristics described above can be applied to the vertical behavior characteristics in ocean water, so detailed explanation of overlapping content will be omitted here.

[0048] Furthermore, as for the more specific details of the process of drifting an HNS simulant on the ocean surface, tracking its movement path, and calculating the floating, dissolving, and sinking behavior characteristics of an HNS as described above, these are matters that a person skilled in the art could appropriately implement by referring to the details of prior art methods for tracking the movement path of a floating body at sea, etc. Therefore, in order to simplify the explanation in this invention, it should be noted that detailed explanations of the details that are obvious to a person skilled in the art from the details of the prior art as described above, or that a person skilled in the art can easily understand and implement by referring to prior art literature, etc., have been omitted.

[0049] Therefore, from the above, it is possible to easily realize a method for estimating the diffusion characteristics of hazardous and harmful substances at sea using a simulator according to an embodiment of the present invention. That is, referring to Fig. 2, Fig. 2 is a flowchart showing the overall configuration of a method for estimating the diffusion characteristics of hazardous and harmful substances at sea using a simulator according to an embodiment of the present invention.

[0050] As shown in FIG. 2, the method for estimating the diffusion characteristics of hazardous and harmful substances at sea using a simulator according to an embodiment of the present invention can be broadly divided into a data collection step (S10) in which a process is performed to collect various predetermined data for estimating the diffusion characteristics of hazardous and harmful substances at sea, including various measurement values ​​measured through a simulation of HNS diffusion characteristics by drifting an HNS simulator on the ocean surface and tracking its movement path; a floating behavior characteristic calculation step (S20) in which a process is performed to calculate floating behavior characteristics based on the data collected in the data collection step (S10); a dissolution behavior characteristic calculation step (S30) in which a process is performed to calculate dissolution behavior characteristics based on the data collected in the data collection step (S10); and a sinking behavior characteristic calculation step (S40) in which a process is performed to calculate sinking behavior characteristics based on the data collected in the data collection step (S10).These steps can be configured to be executed by a computer or dedicated hardware.

[0051] It should be noted that the above calculation steps (S20, S30, S40) do not necessarily have to be performed sequentially in the order shown in FIG. 1, and the order of the calculation steps may be changed, and the calculation steps may be performed in parallel or simultaneously, and may be configured in various ways as needed.

[0052] Furthermore, although not shown, the above method can be configured to further include an output step in which data obtained through the processing steps and processing results of each of the above steps, including the results of each calculated behavioral characteristic, is output in a specific form or format according to a user request or predetermined settings; a database construction step in which data obtained through the processing steps and processing results of each of the above steps, including the results of each calculated behavioral characteristic, is stored in a database according to predetermined settings to construct a database related to HNS behavior characteristics; and a data provision step in which data obtained through the processing steps and processing results of each of the above steps, including the results of each calculated behavioral characteristic, is transmitted to an external device such as a user terminal according to a user request, thereby providing a user-customized information provision service related to HNS behavior characteristics.

[0053] More specifically, the data collection step (S10) can be configured to perform a process of directly inputting or externally receiving various simulation measurement values ​​related to the drift and diffusion characteristics of the HNS, such as travel time, travel distance, travel speed, travel direction, time-dependent diffusion area, and fluctuations in diffusion range, through a simulation of the HNS behavior characteristics using a simulator as described above.

[0054] Furthermore, the floating behavior characteristic calculation step (S20), the dissolution behavior characteristic calculation step (S30), and the sedimentation behavior characteristic calculation step (S40) are performed by referring to the above (Equation 1) to (Equation 4). The configuration can be such that a process for calculating each behavior characteristic is performed as described above.

[0055] In the above-mentioned examples of the present invention, the floating, dissolving and settling behavioral characteristics of HNS are calculated based on data collected through simulations using an HNS simulant. However, the present invention is not necessarily limited to the content shown in the above-mentioned examples. In other words, the present invention can be configured to simulate and estimate various behavioral characteristics other than those shown in the above-mentioned examples. It should be noted that the present invention can be modified and altered in various ways as needed by those skilled in the art without departing from the spirit and essence of the present invention.

[0056] Therefore, as described above, a method for estimating the diffusion characteristics of hazardous and harmful substances at sea using a simulator according to an embodiment of the present invention can be realized, and by utilizing this, a system for estimating the diffusion characteristics of hazardous and harmful substances at sea (HNS) and a customized information provision service for users that provides various information related to the behavior characteristics of hazardous and harmful substances at sea (HNS) in accordance with user requests can be easily realized.

[0057] That is, referring to Figure 3, Figure 3 is a block diagram showing an outline of the overall configuration of a maritime hazardous and harmful substance (HNS) diffusion characteristic estimation system (10) that estimates the behavior characteristics of maritime hazardous and harmful substances (HNS) using the method for estimating the diffusion characteristics of maritime hazardous and harmful substances using a simulator according to the embodiment of the present invention described above with reference to Figures 1 and 2.

[0058] As shown in FIG. 3, a maritime hazardous and harmful substance (HNS) diffusion characteristic estimation system (10) according to an embodiment of the present invention can be broadly configured to include a data collection unit (11) that collects various types of predetermined data for estimating the diffusion characteristics of maritime hazardous and harmful substances (HNS), a behavior characteristic estimation unit (12) that estimates the behavior characteristics of HNS based on the data collected through the data collection unit (11), an output unit (13) that outputs the data obtained from each processing step and the results thereof in accordance with predetermined settings, a database unit (14) that stores the various data obtained from each processing step and the results thereof and constructs a database related to the behavior characteristics of HNS, a communication unit (15) that communicates with external devices via at least one of wireless and wired communication methods and transmits and receives various types of data, and a control unit (16) that controls the overall operation of the above units and the system (10).

[0060] Also, referring to Figure 4, Figure 4 is a block diagram showing an outline of the overall configuration of a maritime hazardous and harmful substances (HNS) information service provision system (20) that uses the method for estimating the diffusion characteristics of maritime hazardous and harmful substances using a simulator according to the embodiment of the present invention described above with reference to Figures 1 and 2 to provide customized information related to the behavior characteristics of maritime hazardous and harmful substances (HNS) according to user requests.
