For extension project construction of Tianwan Nuclear Power Station (TNPS), China, the sediment suspension and diffusion will be caused in the process of blasting toe-shooting and dredging. The chapter analyzed the motion features of tides, waves, and sediment in engineering sea areas, established a 2-D tidal current and sediment mathematical model and conducted verifications through the actual measurements of tidal level, velocity and sediment concentration in accordance with nuclear safety guide rules and sea area use demonstration. Based on this, the advantageous tide types are selected, the source strength of blasting toe-shooting and mud dredging are determined, the mathematical model is used to study the suspended sediment diffusion scope caused by blasting toe-shooting and dredging respectively.
