Embodiment Construction

[0016] The groundwater pollution source evaluation method provided in this embodiment includes the following steps:

[0017] (1) Obtain the image data of the groundwater to be evaluated by an unmanned detector equipped with an infrared spectrum camera, and then calculate the absorbance A of the groundwater through Fourier transform after obtaining the image data, and at the same time use an infrared spectrum camera with the same specification to obtain the image, and the same operation principle to obtain the absorbance Q of clear water;

[0018] (2) load geographical data by three-dimensional engine, described three-dimensional engine selects Delta3D for use, OGRE, OSG, Unity3d, VTK can realize, and described map data comprises factory quantity C, elevation data E and crowd size P of area to be evaluated; The number of people mentioned above is determined by the housing area in the map data, specifically including 0, 2, and 5; 0 means that the number of people is small, 2 mea...

Abstract

The invention discloses an underwater pollution source evaluation method. The method comprises the following steps: firstly acquiring image data of to-be-evaluated underwater through an unmanned detector with an infrared spectrum camera, loading geographic data through a three-dimensional engine; and computing the pollution source level F by importing the underwater depth L, the image data and thegeographic data into a level computation model. The absorbency of the underwater is acquired by loading the infrared spectrum camera on an unmanned aerial vehicle, the pollution source level is computed by loading the geographic data through the three-dimensional engine and combining the underwater depth, and then the probability that the underwater is polluted can be obtained, the periodic detection can be performed on the place with high pollution source, thereby preventing the underwater from being managed after being polluted, and the prevention in advance is made.

Description

technical field [0001] The invention relates to a groundwater pollution source evaluation method, which belongs to the groundwater pollution source rating method. Background technique [0002] The susceptibility of groundwater to pollution mainly refers to the protection of groundwater by formations. Due to the wide distribution of groundwater and the complex surface environment, it is an important means to prevent and supervise groundwater pollution to carry out groundwater pollution susceptibility assessment and reasonably carry out pollution risk zoning. [0003] At present, the susceptibility of groundwater pollution is mostly evaluated based on the DRASTIC method issued by the US Environmental Protection Agency. The main parameters of the DRASTIC method are depth to groundwater, net recharge (netRecharge), aquifer media (Aquifer media), soil media (Soil media), topography (Topography), impact of vadose zone media (Impact of the vadose zone media), aquifer hydraulic co...
