Precise Hydrodynamic Numerical Simulation of Sea Area Haibin Lv, Li Chen, Jikun Lu and Junsheng Liu Abstract The tidal current field and tidal energy at sea area around Lianyungang city are studied. Current flows from northeast to southwest direction at maximum flood moment. Because of the terrain effects, current flows to the southeast after Linhong estuary coast. Promontory effect is not obvious around the Xishu headland, and current speed increases. The flood current from the northeast seems stronger during the flood tide, eastard tidal kinetic energy degresses to the southwest, the maximum value is more than 1,100 kW/m; At the east of Xishu headland has a ring of low energy region; At the northwest of marine environmental monitoring station is also an annular energy region; On the headland area (such as the Xilian Island North, Xishu headland, Near East od Lan Mountain), high energy and low energy area coexists. Keywords Tidal current • Tidal energy • Numerical simulation
73.1 Introduction In recent years, marine pollution disaster such as oil spill, land-based pollutant discharging, hazardous chemicals leakage, red tide and Enteromorpha increased significantly. SST, waves and currents are important environmental dynamic factors and decisive factors of pollutant migration and diffusion; therefore, to carry out three-dimensional ocean environmental factors (temperature, current), forecast has important significance on marine safety, disaster prevention and mitigation, marine national defence construction. We are facing a major challenge to build China’s H. Lv (*) · J. Liu School of Geodesy and Geomatics Engineering, Huai Hai Institute of Technology, Lianyungang, China e-mail: [email protected] L.

Marine Science and technology strength, to understand marine environmental law and develop the marine environment forecast ability, to make our country coastal social economy to achieve sustainable development and provide the necessary support and protection of marine environment to national security [1]. Marine numerical prediction system is an embodiment of comprehensive national science and technology strength [2, 3] researched extratropical cyclone gale forecast method at Haizhou Bay [4] studied on the Gulf of Haizhou seiche [5] studied on accretion process of silty beach profile. This paper presents how to simulate the tidal current field and tidal energy at sea area around Lianyungang city. Observation data and methodology are described in Sect. 73.2; Verification is presented in Sect. 73.3; Numerical simulation analysis is offered in Sect. 73.4. Finally, a conclusi
