Abstract
Description
Technical Field
[0001] The present invention relates to a method for grasping the diffusion characteristics of various hazardous and noxious substances (HNS) flowing into the ocean. More specifically, generally, for the environmental impact assessment associated with the outflow or discharge of HNS into the ocean, it is of utmost priority to simulate the diffusion of HNS in the ocean and accurately grasp the diffusion characteristics of HNS in the ocean. However, to achieve this, although it is necessary to disperse HNS in the actual ocean and observe the diffusion process, it is impossible to disperse HNS in the actual ocean due to the danger of HNS, and it is difficult to accurately grasp the diffusion characteristics. To solve the problems of the conventional HNS diffusion characteristic estimation method, the present invention relates to a method for estimating the diffusion characteristics of hazardous and noxious substances at sea using a simulation body, which is configured to be able to grasp the diffusion characteristics of HNS using a simulation body instead of dispersing HNS in the ocean for grasping the diffusion characteristics of HNS in the ocean.
[0002] In addition, since it is impossible to disperse HNS in the actual ocean and measure as described above, to solve the problems of the conventional HNS diffusion characteristic estimation method, which had difficulty in accurately grasping the diffusion characteristics, HNS is classified into 12 groups based on its physicochemical properties, and based on the results of observing and analyzing the diffusion characteristics of HNS using a simulation body for each of the three behavior characteristics of floating, dissolution, and sedimentation, a process for calculating the floating behavior characteristics, dissolution behavior characteristics, and sedimentation behavior characteristics of HNS in the ocean is configured to be performed. Thereby, the present invention relates to a method for estimating the diffusion characteristics of hazardous and noxious substances at sea using a simulation body, which is configured to be able to more accurately grasp the diffusion characteristics of HNS without the need to actually disperse HNS in the ocean and measure.
Background Art
[0003] In recent years, as environmental issues have gained global attention, there has also been increased interest in hazardous and noxious substances (HNS) that are discharged or leaked into the ocean and cause various adverse effects on the marine environment.
[0004] In response to this, various technologies have been proposed to enable rapid and effective responses by predicting the diffusion risk radius of hazardous substances in marine environments or by detecting hazardous substances and determining their flow paths, as shown in, for example, Korean Registered Patent No. 10-1740720, "Device and Method for Predicting the Diffusion of Hazardous Substances," and Korean Registered Patent No. 10-1751020, "Multi-Satellite-Based Continuous Detection Method and Apparatus for Hazardous Substances." However, the above-mentioned conventional technologies had the following limitations.
[0005] More specifically, the Hazardous Substances (HNS) currently designated under the Marine Environment Management Act consist of a total of 799 types. In order to assess the impact on the marine environment if these HNS are released or discharged into the ocean, it is essential to simulate and predict the diffusion of HNS in the ocean. For this purpose, accurately understanding the diffusion characteristics of HNS in the ocean is of paramount importance.
[0006] To accurately understand the diffusion characteristics of HNS in the ocean, the most accurate method would be to actually scatter HNS in the ocean and observe its diffusion process. However, due to the dangers of HNS, scattering HNS in the ocean is currently impossible under existing laws.
[0007] Therefore, in order to solve these problems, it is necessary to be able to obtain measurement results equivalent to or similar to those in reality without dispersing HNS into the ocean, but the conventional technology described above has the limitation that it does not describe such a technology.
[0008] Therefore, in order to overcome the limitations of the conventional technology described above, it would be desirable to present a method for estimating the diffusion characteristics of hazardous substances at sea using a newly configured simulated body that is designed to more accurately grasp the diffusion characteristics of HNS instead of scattering HNS into the ocean. However, at present, no device or method has been proposed that satisfies all of these requirements. [Prior art documents] [Patent Documents]

[0010] The present invention aims to solve the problems of the prior art described above. Therefore, the objective of the present invention is that, in order to assess the environmental impact associated with the outflow or discharge of HNS into the ocean, it is of paramount importance to simulate the diffusion of HNS in the ocean and accurately understand the diffusion characteristics of HNS in the ocean. However, in order to do this, it is necessary to scatter HNS in the actual ocean and observe the diffusion process. However, due to the dangers of HNS, it is impossible to scatter HNS in the actual ocean, and in order to solve the problems of the conventional method for estimating the diffusion characteristics of HNS, which has been difficult to accurately understand, the present invention aims to provide a method for estimating the diffusion characteristics of hazardous substances at sea using a simulated body, which is configured to allow the diffusion characteristics of HNS to be understood using a simulated body instead of scattering HNS in the ocean.

This method classifies HNS into 12 groups based on its physicochemical properties, and based on the results of observing and analyzing the diffusion characteristics of HNS using simulated bodies for each of the three behavioral characteristics of suspension, dissolution, and sedimentation, it calculates the suspension behavior characteristics, dissolution behavior characteristics, and sedimentation behavior characteristics of HNS in the ocean.

Advantages of the Invention
[0021] As described above, according to the present invention, HNS is classified into 12 groups based on its physicochemical properties, and based on the results of observing and analyzing the diffusion characteristics of HNS using simulation models for each of the three behavior characteristics of floating, dissolution, and sedimentation, a method for estimating the diffusion characteristics of maritime hazardous and noxious substances using simulation models is provided, which is configured to perform a process of calculating the floating behavior characteristics, dissolution behavior characteristics, and sedimentation behavior characteristics of HNS in the ocean. Thus, even without spreading and measuring HNS in the actual ocean, the diffusion characteristics of HNS can be grasped more accurately.
[0022] Furthermore, the present invention provides a method for estimating the diffusion characteristics of hazardous substances at sea using a simulated body configured to more accurately grasp the diffusion characteristics of HNS using the simulated body as described above. For environmental impact assessments associated with the outflow or discharge of HNS into the ocean, it is of paramount importance to simulate the diffusion of HNS in the ocean and accurately grasp the diffusion characteristics of HNS in the ocean. However, this requires actually scattering HNS in the ocean and observing the diffusion process. However, due to the dangers of HNS, it is impossible to scatter HNS in the actual ocean, and the problem of conventional methods for estimating the diffusion characteristics of HNS, which made it difficult to accurately grasp the diffusion characteristics, can be solved.

[Figure 3] Referring to Figures 1 and 2, this is a block diagram schematically showing the overall configuration of a maritime hazardous substances (HNS) diffusion characteristic estimation system that estimates the behavioral characteristics of maritime hazardous substances (HNS) using the maritime hazardous substances diffusion characteristic estimation method using a simulated body according to the embodiment of the present invention described above. [Figure 4] Referring to Figures 1 and 2, this is a block diagram schematically showing the overall configuration of a maritime hazardous materials (HNS) information service provision system that provides various information related to the behavioral characteristics of maritime hazardous materials (HNS) customized according to user requests, using the maritime hazardous materials diffusion characteristics estimation method using a simulated body according to the embodiment of the present invention described above. [Modes for carrying out the invention]
[0024] The following describes a specific example of the method for estimating the diffusion characteristics of hazardous substances at sea using a simulated body according to the present invention, with reference to the attached drawings.
[0025] It should be noted that the content described below is merely one embodiment for carrying out the present invention, and the present invention is not limited to the content of the embodiment described below.
[0026] Furthermore, please note that in the following description of embodiments of the present invention, detailed explanations have been omitted in order to simplify the explanation, where there are parts that are identical or similar to the content of the prior art, or parts that are judged to be easily understood and implemented by those skilled in the art.
[0027] Next, with reference to the drawings, the specific details of the method for estimating the diffusion characteristics of hazardous substances at sea using a simulated body according to the present invention will be explained.
[0028] More specifically, conventionally, in order to assess the impact of various hazardous and noxious substances (HNS) released into the ocean on the marine environment, accurately understanding the diffusion characteristics of HNS in the ocean is of paramount importance. However, it is not possible to simulate the diffusion process by actually dispersing HNS in the ocean, making it difficult to accurately understand the diffusion characteristics based on actual observations.
[0029] In response to the above-mentioned problems, the present invention proposes a method for estimating the diffusion characteristics of hazardous substances at sea using a simulated body, which is configured to allow for the understanding of the diffusion characteristics of HNS in a manner close to reality, instead of scattering HNS into the ocean.
[0030] To achieve this, the present invention classifies HNS into 12 groups based on their physicochemical properties, observes and analyzes the diffusion characteristics of HNS using simulated bodies for each of the three behavioral characteristics: floating, dissolution, and sinking. Based on the analysis results, the drift characteristics, horizontal diffusion characteristics, vertical behavior characteristics, and vertical mixing characteristics of HNS on the ocean surface are calculated, and the floating behavior characteristics, dissolution behavior characteristics, and sinking behavior characteristics of HNS are estimated by combining the calculation results. This process allows for a relatively accurate understanding of the diffusion characteristics of HNS without actually scattering HNS in the ocean and performing measurements.
[0031] More specifically, referring to Figure 1, Figure 1 is a diagram that shows an example of HNS classification applied to the method for estimating the diffusion characteristics of hazardous substances at sea using a simulated body according to an embodiment of the present invention, organized as 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 into evaporation (E), dissolution-evaporation (ED), suspension evaporation (FE), suspension-evaporation-dissolution (FED), suspension (F), suspension-dissolution (FD), dissolution-evaporation (DE), dissolution (D), sedimentation-dissolution (SD), and sedimentation (S), and solid HNS into suspension-dissolution (FD), dissolution-evaporation (DE), dissolution (D), sedimentation-dissolution (SD), and sedimentation (S), with each behavioral characteristic classified accordingly. Then, a method is proposed for observing and analyzing three of the 12 classified HNS behavioral characteristics—suspension, dissolution, and sedimentation—using a simulated body.
[0033] Specifically, regarding the floating behavior characteristics, in order to estimate the floating behavior characteristics of HNS, it is necessary to understand the drift characteristics and horizontal diffusion characteristics on the ocean surface. To achieve this, in this invention, a vinyl membrane-type ocean surface floating HNS simulant was allowed to drift on the ocean surface, and its movement path was tracked. From the movement time and distance, drift characteristics such as drift velocity and direction were determined.
[0034] Here, the drift velocity can be calculated using the following equation (Equation 1).
[0035]
number
[0036] Furthermore, regarding horizontal diffusion characteristics, we tracked the movement paths of three or more floating HNS (Heat-Neutral Sulfur-Sulfur) simulated bodies on the ocean surface and, through simultaneous positional analysis of the movement paths of each simulated body, we grasped diffusion characteristics such as variations in diffusion area and diffusion range over time.
[0037] Furthermore, the diffusion area can be calculated from the movement paths of multiple simulated objects that departed from the same point as the variance of the distance between the simulated objects, as shown in (Equation 2) below.
[0038]
number
[0039] Here, in (equation 2), N is the number of simulated bodies, and xi and yi are the transitions of the i-th simulated body, respectively. The movement path is shown.
[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 simulated body is introduced into the target depth, and its movement path is tracked. The drift characteristics and horizontal diffusion characteristics in ocean water can then be determined in the same way as when calculating the drift characteristics and horizontal diffusion characteristics on the ocean surface as described above.
[0041] Furthermore, the vertical behavior characteristics in ocean water were determined by deploying two or more underwater HNS simulated bodies at two or more different depths, tracking their movement paths, and analyzing their movement speed as shown in (Equation 3) below. It can be calculated using the successor equation.
[0042]
number
[0043] Here, in (Equation 3), ω is the vertical velocity, δz is the difference in water depth of the simulated body, and u and v are their respective This shows the flow velocity in the x and y directions.
[0044] Furthermore, the vertical mixing characteristics in ocean water are calculated by deploying underwater HNS simulated bodies to two or more depths (z1, z2), tracking their movement paths, and using the movement speed as shown in (Equation 4) below. It is possible.
[0045]
number
[0046] Here, in (Equation 4), k is the vertical diffusion coefficient, and Uz1 and Uz2 are the moving speeds at z1 and z2, respectively. In degrees, δz represents the difference between z1 and z2, respectively.
[0047] Next, regarding the settling behavior characteristics, it is necessary to understand the vertical behavior characteristics in ocean water. In this case, the characteristics understood from the dissolution behavior characteristics mentioned above can be applied to the vertical behavior characteristics in ocean water, so a detailed explanation of the overlapping content will be omitted here.
[0048] Furthermore, regarding the more specific details of the process of tracking the movement path of HNS simulated bodies by letting them drift on the ocean surface as described above, and calculating the buoyancy, dissolution, and sinking behavior characteristics of HNS, it should be noted that this invention omits detailed explanations of aspects that are obvious to those skilled in the art from the content of the prior art, or that can be easily understood and implemented by those skilled in the art by referring to prior art literature, etc., in order to simplify the explanation.
[0049] Therefore, based on the above, a method for estimating the diffusion characteristics of hazardous substances at sea using a simulated body according to an embodiment of the present invention can be easily realized. Specifically, referring to Figure 2, Figure 2 is a flowchart that schematically shows the overall configuration of a method for estimating the diffusion characteristics of hazardous substances at sea using a simulated body according to an embodiment of the present invention.
[0050] As shown in Figure 2, the method for estimating the diffusion characteristics of hazardous substances at sea using a simulated body according to an embodiment of the present invention can be configured to be performed by a computer or dedicated hardware, and may include the following steps: a data collection step (S10) in which a simulated HNS body is allowed to drift on the ocean surface and its movement path is tracked, and various predetermined data for estimating the diffusion characteristics of hazardous substances at sea are collected, including various measured values measured through simulations of HNS diffusion characteristics; a floating behavior characteristic calculation step (S20) in which floating behavior characteristics are calculated based on the data collected in the data collection step (S10); a dissolution behavior characteristic calculation step (S30) in which dissolution behavior characteristics are calculated based on the data collected in the data collection step (S10); and a settling behavior characteristic calculation step (S40) in which settling behavior characteristics are calculated based on the data collected in the data collection step (S10).
[0051] It should be noted that the above calculation stages (S20, S30, S40) do not necessarily have to proceed sequentially in the order shown in Figure 1. The order of the calculation stages can be changed, and the calculation stages can proceed in parallel or simultaneously. In short, they can be configured in various ways as needed.
[0052] Furthermore, although not shown in the diagram, the above method may be configured to further include an output stage in which data obtained through the processing steps and results of each stage, including the calculated results of each behavioral characteristic, are output in a specific form or format according to the user's request or predetermined settings; a database construction stage in which data obtained through the processing steps and results of each stage, including the calculated results of each behavioral characteristic, are stored in a database according to predetermined settings, thereby constructing a database related to the behavioral characteristics of the HNS; and a data provision stage in which data obtained through the processing steps and results of each stage, including the calculated results of each behavioral characteristic, are transmitted to an external device such as a user terminal in response to the user's request, thereby providing a customized information provision service for the user related to the behavioral characteristics of the HNS.
[0053] More specifically, the data acquisition stage (S10) described above can be configured to directly input or receive from an external source various simulated measurement values related to the drift and diffusion characteristics of the HNS, such as movement time, movement distance, movement speed, movement direction, and changes in diffusion area and diffusion range at each time, through HNS behavior characteristic simulation using a simulated body as described above.
[0054] Furthermore, the above steps for calculating the floating behavior characteristics (S20), the dissolution behavior characteristics (S30), and the settling behavior characteristics (S40) are performed by referring to (Equation 1) to (Equation 4) above. The system can be configured to perform a process that calculates the behavioral characteristics of each component.
[0055] In the above-described embodiments of the present invention, the present invention was explained using the example of calculating the buoyancy, dissolution, and sedimentation behavior characteristics of HNS based on data collected through simulations using HNS simulated bodies. However, the present invention is not necessarily limited to the contents shown in the above embodiments. In other words, the present invention can be configured to simulate and estimate various behavior characteristics other than those shown in the above embodiments. It should be noted that, without departing from the spirit and essence of the present invention, those skilled in the art can modify and change the configuration as needed.

Using this, a system for estimating the diffusion characteristics of hazardous marine substances (HNS) and a user-customized information provision service that provides various information related to the behavioral characteristics of hazardous marine substances (HNS) according to the user's request can be easily realized.

[0058] As shown in Figure 3, the marine hazardous substances (HNS) diffusion characteristics estimation system (10) according to an embodiment of the present invention can be broadly configured to include: a data collection unit (11) that performs processing to collect various predetermined data for estimating the diffusion characteristics of marine hazardous substances (HNS); a behavioral characteristics estimation unit (12) that performs processing to estimate the behavioral characteristics of HNS based on the data collected through the data collection unit (11); an output unit (13) that performs processing to output each processing process and the resulting data according to predetermined settings; a database unit (14) that stores each processing process and the resulting data and performs processing to construct a database related to the behavioral characteristics of HNS; a communication unit (15) that communicates with external devices by at least one method of wireless or wired communication and performs processing to send and receive various data; and a control unit (16) that performs processing to control the operation of each of the above units and the overall system (10).
