The invention discloses a coastal protection structure employing a mangrove forest and corals to dissipate waves layer by layer, and relates to the technical field of coastal engineering. The coastal protection structure employing the mangrove forest and the corals to dissipate the waves layer by layer comprises a foundation base, a horizontal reef platform, manual mangrove forest units and manual coral units. The coastal protection structure is characterized in that the coastal protection structure is entirely arranged in an intertidal zone; the foundation base is formed by a plurality of concrete blocks that are mutually staggered and hinged; the manual mangrove forest units are fixed in holes reserved in the foundation base; the horizontal reef platform adopts triangular grids; each corner of each triangular grid is connected with a tree trunk of one manual mangrove forest unit by using an anchor chain and a float device correspondingly; the manual coral units are arranged in a staggered manner and are fixed to the triangular grids of the horizontal reef platform. By adopting a manual model for simulation and by combining the wave dissipating characteristics of respective structures of tree crowns of the mangrove forest, root systems of the mangrove forest and the corals at different heights, the protection capability of a coast to the waves is improved without changing an original coastal morphological base, and a water ecological environment nearby the coastal protection structure is improved.

A high sand content bore simulation testing method relates to a testing method for simulating high sand content bore in a river mouth model test, particularly relates to a method and a device for simulating the bore head sand content during the bore and belongs to the field of coastal engineering model tests. A test water tank device for simulating the high sand content bore and a method for utilizing the device to conduct simulation test are further provided. The test water tank device comprises a variable water head high level water tank, a test water tank and an underground reservoir. A tail door and the variable water head high level water tank are utilized to adjust the flowing speed of water in the water tank to reach the preset value, a fast gate is closed, the water flow is stopped and generates the bore in the water tank, the bore upwells upstream from the gate and drives sand in a sand tank, and vertical sand distribution in the water tank is measured at the moment to obtain the natural-state vertical sand distribution characteristics. The device and the method specially used for simulating the vertical sand distribution of the bore are provided. The sand distribution obtained by the method is similar to the natural sand distribution. The device meets the law of similarity.

The present invention relates to devices and methods for tracking movement in a marine environment. At least one tracking device that is adapted to be deployed on a surface of the water, wherein the tracking device is capable of moving along the same trajectory of a desired object. Data from the tracking devices are received by at least one satellite, transmitted to a database, and used to determine the forecasted trajectory of the desired object. All data collected from deployed tracking devices may be integrated into a spatial data repository for analysis and reporting using GIS and associated information technologies, thereby allowing for more accurate decision-making and asset deployment during a fluid spill or similar marine contamination event. The present invention also allows for the collection and modeling of accurate localized sea current data, which may assist with marine and coastal engineering works such as shoreline protection and port dredging.

The invention discloses a floating type device integrating wave dissipation and offshore culture, and belongs to the field of comprehensive utilization of structures of coastal engineering. The floating type device comprises wave dissipation units with a net cage function, a floating type wave prevention box and an anchoring structure, and is characterized in that each wave dissipation unit consists of a basic block body, an artificial rigid plant and a net cage type wave dissipation drum; the wave dissipation units are fixedly embedded into the wave prevention box by the basic block bodies and are spliced with one another to form an integrated structure; the whole device floats on a sea surface and is fixed at the seabed through anchor chains. By the combination of three functions of wave dissipation of the floating type wave prevention boxes, revetment of the rigid plants and offshore culture, the floating type device integrating wave dissipation and offshore culture is provided. Due to the design, the wave dissipation performance of the floating type wave prevention boxes can be improved, and good conditions are provided for offshore culture.
