Embodiment

[0051] Taking an important navigation channel of a large river as the research area, this area is a high risk area of ​​oil spill accidents, and the specific parameters are as follows:

[0052] Type of oil spill: light oil (gasoline);

[0053] Oil spill volume: 50 tons, leak duration 10 minutes;

[0054] Wind: wind speed 1.5 m / s, wind direction is north wind;

[0055] Upstream water volume: 3500m 3 / s;

[0056] Downstream water depth: 2.5 meters.

[0057] Convert the electronic map of the nearby waters into a readable data format using GIS software, and run the hydrodynamic model to solve the flow field.

[0058] After calculation and repeated adjustment of parameters, finally obtain the following figure 2 The flow field shown, different colors represent different flow velocities. Assuming that a gasoline leakage accident occurs in the nearby waters, the diffusion of light oil within 6 hours after the leakage is simulated to provide basic data for emergency measures. Us...

Abstract

Aiming at the oil spillage accidents which possibly occur to ships conveying oil substances in inland river water bodies such as rivers and long and narrow reservoirs and the like, the invention provides a technology for predicting the oil film diffusion process after oil spillage occurs by utilizing combination of a dynamic model and an oil spilling diffusion model on the basis of a geographic information system (GIS). The technology has the characteristics that the response speed is fast and the cost is low, and has very important realistic significance for shipping management and environmental protection of the inland river water bodies.

Description

technical field [0001] The invention belongs to the field of water environment management, and in particular relates to a combination of a hydrodynamic model and an oil spill model, based on a GIS platform, to simulate the diffusion process after oil spills occur in rivers. Background technique [0002] Petroleum is the blood of industry. With the deepening of industrialization, the extraction and use of petroleum are gradually increasing, and the scale of its transportation is also gradually expanding. During the transportation of petroleum and related products, leakage accidents occur from time to time. Every year, there are 41 major oil spill accidents of more than 1,000 tons in the ocean around the world, and there are nearly 100 accidents of hundreds of tons, but the accidents with oil spills of tens of tons cannot be accurately counted. The 1989 crude oil spill in the waters off Alaska leaked crude oil equivalent to the daily consumption of the United States; the oil ...
