| 英文摘要 | Mastering the subaqueous physical state of artificial reefs (ARs) is critical for assessing the benefits of ARs. Tradition survey methods suffer shortcomings such as low efficiency and incomplete information and cannot meet the requirements for the precise monitoring of ARs. This study established a high -precision DEM (digital elevation model) of ARs using a multibeam sonar system. Meanwhile, this study conducted a quantitative analysis of the distribution, height, volume, and complex topographic features of ARs using the GIS (geographic information system) spatial analysis method. The high -precision DEM was tested in an offshore AR area in Shandong Province, obtaining the following results. The AR area has a water depth of -9.92 ~ -6.73 m. The ARs in the area are stacked in piles with different distances, with a total reef volume of 5 458.49 m~3. Meanwhile, 50% of the ARs have a height of 1.48 ~ 1.82 m. The terrain characteristic variables such as slope, curvature, rugosity, and topographic relief intensively show high values in the reef distribution area. Affected by their own gravity and local hydrodynamic force, the ARs have a subsidence depth of about 0.5 m, leading to the formation of the special erosion and silting terrain around the ARs. This study can provide technical and data support for the monitoring and assessing the physical stability of ARs and thus is practically significant. |
