The Research Of Static Equilibrium Headland-bay Coast Theory And Its Application To Coasts Of Hainan

Because of the utilization and development of the oceans, it comes to be a muchmore important issue that designing coastal engineering properly and assessing theimpact of coastal building correctly to avoid damage of coastal resources. With thehelp of mathematical tools and mathematical methods, the impact of projects on thecoast is predicted, and the results are analyzed and evaluated in this paper.Considering the main reasons causing shoreline evolution, a coastalhydrodynamic model for the project region is established. By simulating longshorecurrent field and calculating longshore sediment transport rate to analyze themovement rule of nearshore sediment. Then predict the evolution on the shoreline bystatic equilibrium head-bay empirical formula and numerical simulation. In this paperthe impact of projects on the coast is the main research content combined with theanalysis of longshore current and sediment transport rate.In engineering applications, a coastal hydrodynamic model for the nearshore ofthe supporting pier for the Guodian Hainan southwest power plant site relocationprogram is established. Analyzing the longshore current through simulating thelongshore current field and near-shore sediment transport field which contributes theshoreline evolution. Then predict the equilibrium shoreline by static equilibriumhead-bay parabolic model and compare with the simulated shoreline by numericalmethod. It shows that the shoreline change and the calculated results of longshorecurrents and sediment transport rate are consistent. By comparing the extent of thesiltation of three programs, a rational evaluation for the projects is given and ascientific basis for the comparison of programs are given.
