A research on the coastal mantle communities in South Korea and Japan was carried out. This study was accomplished by using syntaxa and hierarchical system of the coastal mantle communities in South Korea and Japan in terms of the Zurich-Montpellier School's method. The coastal mantle communities in South Korea and Japan are included in the Rosetalia rugosae of northern type and the Viticetea rotundifoliae of southern type, which are characterized by Rosa rugosa and Vitex rotundifolia, respectively. The coastal mantle communities in South Korea are subordinated and are considerably corresponded to those which already identified in Japan. Each syntaxon of the coastal mantle communities in South Korea and Japan is briefly characterized floristically and ecologically, and their distribution is shown on maps.

The prediction of the dynamic behaviors of buoyant water discharges into a large volume of water bodies, the flows of water accompanying the density differences due to temperature differences and sometimes also to salinity differences, have attracted great concern over several decades. Heated water surface discharges from power plants and freshwater discharges in estuaries are typical examples of the buoyant flows. (omitted)

A three-dimensional numerical model (POM) is implemented to examine coastal upwelling in the northern Japanese coastal region with the passage of Typhoon Oliwa in September 1997. Observed sea surface temperature (SST) decreased suddenly ranging from $-6\;to\;-7^{\circ}C$ in the coastal regions, and such a SST decrease state lasted for more than ten days after the typhoon passed. The model successfully reproduces the observation and gives a clear explanation, the sudden decrease of SST occurred in the process of coastal upwelling with Ekman dynamics. The model also describes the sea surface cooling in the open ocean with vertical velocity.

Coastal wave and tide information is very important in various occasions for port and harbor engineers, in the stages such as port and harbor planning, maritime structure design, maritime construction management, and coastal disaster study This paper introduces recent improvement of Japanese coastal wave-tide observation and information system named as NOWPHAS (Nationwide Ocean Wave information network for Ports and HArbourS). Development and improvement of the NOWPHAS has been achieved during recent decade in the following points of view (Nagai,2002a,2002b). (omitted)

During typhoon periods, coastal regions are often directly flooded by typhoon-surges. There are also many cases where coastal regions are inundated by river inundations or dam breaks. However, most studies on coastal flooding by typhoons have been restricted to cases involving the sea. Flooding by river inundation has been excluded in those studies. Usually ocean numerical models are not applied to river flow because the governing equations for ocean flow and river flow are not the same. For a coastal flooding simulation with river inundation, POM, the three-dimensional numerical ocean model, was applied to the popular river flow problems, dam-break problem, and flows over a spillway. The simulated results showed good agreement with other numerical simulations and measured data, suggesting the possibility of using POM in coastal flooding simulations involving direct coastal surges and river inundations.

The purpose of this study is investigated to suggest the governmental policy and guideline required to establish the coastal zone management and development plan in the Pusan metropolitan city. The results are found as follows; first, a new definition of 'coastal zone' is introduced based on the geophysical characteristics in the city. Second, new policy-oriented guidelines are built on the basis of the coastal function from the viewpoint of the coastal zone management. Third, the coastal zone of the city is classified into 3sub-zone by the geophysical characteristics. Fourth, the comprehensive coastal zone management and development plan is suggested.

Understanding the flow circulation is of primary importance for studies of marine ecology and Pollution protection etc. However the circulation in coastal area is complicated with various processes and can not be considered as forced only by tides. The coastal area off South China is now playing an important role in economic development in southeast Asia with Hong Kong, Macao, Guangzhou and other cities situated in its central part (Fig. 1).

Beaches and low-tying coastal areas have been seriously eroding at many places along the global coastlines during the past century. The coastal erosion problem during the next century is said to be potentially worse due to the sea-level rise by global warming. Coastal erosion, whatever the time scale is, is the result as a response of land to oceanic, atmospheric, and human impacts. (omitted)

As wind waves generated in deep water approach nearshore zone, they experience various physical phenomena caused by bathymetric variations, nonlinear interactions among different wave components and interferences with man-made coastal structures. Among these, the bathymetric variations may play a significant role in the change of wave climate. The accurate calculation of reflection and transmission coefficients of incident waves over a bottom topography is indispensible for the proper and economical design of coastal structures. (omitted)
