In the coasting area, severe storm and wind wave flood the cities and have bad damage on structures. Most severe storm surges are caused by strong cyclones, as we know wind is the most important factor. This study coupled storm and wave models together, considering wind stress and radiation stress to simulate the storm processes. For the study, we focus on temperate storm surge in the Bohai Bay which are caused by temperate cyclone or front winds. The simulating work performed before and after considering the effect of radiation stress on water level and current during storm process. The comparison shows that the effect of the radiation stress on water level and current speed depends on the different storm surge process, the influenced degree has a relationship with the distribution of wind stress. For example, Bohai bay is controlled by NE wind, the current speed increased obviously due to the effect of radiation stress, and the water level rose accordingly.

The study focuses on achieving a fast, continuous and high-resolution predicting model for temperate storm surge for Bohai Bay. Harmonic analysis was applied to provide open boundary conditions; and local deepening, water range reducing were to deal with the boundary of shallow water. The model could achieve the non-linear effect between storm surge and astronomical tide totally. Based on the upper conditions, three storm processes were simulated separately in 5min by the above-mentioned numerical model. Final results show that computed results are agreed well with observed values in three sea level and water elevation processes. We believe the model with great applicable value can accurately forecast sea levels and elevations due to storm surge in this region.

The electrochemical treatment of wastewater containing 2, 4, 6-trichlorophenol has been carried out experimentally with synthetic boron-doped diamond (BDD) thin film electrodes. Removal rate of COD, instant current efficiency (ICE) and energy consumption were investigated under different current density. The influence of supporting media is reported, which plays an important role in determining the global oxidation rate. The oxidative chloride is stronger than peroxodisulphate. The electrochemical characteristics of boron-doped diamond electrodes were investigated in comparison with active coating Ti substrate anode (ACT). The experimental results show that BDD is markedly superior to ACT due to its different absorption properties. © (2012) Trans Tech Publications, Switzerland.
