  • In this study, numerical modeling was performed to investigate influence of the apron shape on the discharge performance of the sluice for tidal power plant. The numerical modeling was carried out for comparison of the difference in the discharge coefficient when the apron width, slope, and the length of the horizontal section were different, without considering change in the shape of the sluice caisson itself. The modeling result showed that significant discrepancy in terms of the overall discharge performance appeared according to the apron geometry. In order to achieve maximum discharge performance of the sluice caisson, it is desirable to make the design by putting a space equivalent to the width of the sluice caisson on its both sides, by making the apron slope be 1:5, and by keeping length of the horizontal section to be 50 m that is corresponding to the streamwise length of the sluice caisson.

  • The purpose of this study is to investigate distribution of the vegetation and insects of coastal dunes in the Yangyang area. The field survey was carried out Osan and Dongho coastal dunes during the period from June to July 2008. A total of 68 taxa were identified including 30 families, 60 genera, 59 species, and 9 varieties. 1 species(Glehnia littoralis) was recorded as designated rare plant of Korea Forest Service. The naturalized plants were 8 families, 13 species. The urbanization rate of naturalization index was 4.8% and 19.1% respectively. The land insect appeared with the 10 order, 23 families including 10 Korean specific species and 16 environmental indicator species for coastal dune. The species in Order Coleoptera was most, followed by Hemiptera, Orthoptera and Odonata respectively.

  • The Korean peninsula has a number of coastal sites where the rhythmic rising and lowering of water surface due to tides result in strong tidal current. The kinetic energy of these currents can be efficiently exploited by using tidal current turbines. The pilot tidal current power plant is to be constructed at the Uldolmok between Chindo and Haenam. Extensive coastal engineer ing research works have been carried out. This paper describes some observation results of field campaign, design of the supporting structure of a pilot plant of 1,000kW and a future tidal current power plant and so on.

  • The pilot tidal current power plant is to be constructed at the Uldolmok between Chindo and Haenam, during next year. and extensive coastal engineering research works have been carried out. In this paper we describes some observation results of the tide and tidal current. as well as modeling work in order to investigate the tide and tidal current regime change in relation to the tidal current power plant (TCPP) construction. The special modeling skill in order to consider the turbine operation in the TCPP is developed and applied to the estimation for the flow regime change by the simple layout of the tidal current power plant.
