Tourist behavior has been a major topic in tourism research. Since the construction of Saemangeum seawall, May 2010, it has been working actively to make a tourist complex fishing port project of Bi-eung port, with the increase of tourists visiting to Saemangeum seawall and Bi-eung port. The purpose of this study is to analyze tourist behaviors conducted in Bi-eung port of Gunsan area. Most of the tourists were the residence of the Jeonbuk, and one-day tourists mostly consisted of families and friends. It was examined that the main destinations were Saemangeum seawall and Bi-eung port. The major complaints of tourists were the lack of parking and convenience facilities. In order to activate the tourism of Bi-eung port, it is required the landscape maintenance and place marketing of Bi-eung port. The satisfaction indicators about tourism base on facilities such as accessibility, promotion and information, tourism products and food, linkage of tourist places and tourism resource with surrounding areas, and the related tourism programs show as below average, respectively. Seven kinds of tourism infrastructure as measured by indicators below average in satisfaction with the analysis but Comprehensive assessment as a tourist destination was the relatively high levels.

Wave overtopping is one of the most important processes for the design of seawalls. The term "wave overtopping" is used here to refer to the processes where waves hit a sloping structure run up the slope and, if the crest level of the slope is lower than the highest run up level, overtop the structure. Wave overtopping is dependent on the processes associated with breaking wave. A numerical model based on Navier-Stokes equation and the Marker-density function for predicting wave overtopping of coastal structures is developed in this paper. In order to evaluate the present model, two simulations are tested. One is overflow without waves at vertical seawall, and the other is wave overtopping at sloping seawalls.

A costal improvement project is designed for preventing disasters on the coast, improving costal environment, and promoting costal functions, so it is different from the one for developing coasts. However, the costal improvement project also affects the surrounding environment and it may damage the costal environment in some cases. In line with this, this study was carried out to provide the guideline to the review on environmental conditions, which should be performed in the stage of establishing the plan for a costal improvement project, so that the influence affecting marine environment can be reduced and more efficient coastal project can be planned. The costal improvement project is different in the degree of affecting the costal environment according to kinds, scales, and regions. Accordingly, in this study the state of the coastal improvement project and involved problems were analyzed. The prior environmental review system was divided into a seawall-installation project, a marine construction such as the installation of submerged breakwater and jetties, and a project for creating water-friendly coast including a park without marine landfill. The main items for reviewing these specific projects were presented.

A Level 3 reliability analysis has been performed for wave run-up and overtopping on a sloping seawall. A Monte-Carlo simulation was performed considering the uncertainties of various variables affecting the wave overtopping event. The wave overtopping probability was evaluated from the individual wave run-up by using the wave-by-wave method, while the mean overtopping rate was calculated directly from the significant wave height. Using the calculated overtopping probability and mean overtopping rate, the maximum overtopping volume was also calculated on the assumption of two-parameter Weibull distribution of individual wave overtopping volume. In addition, by changing wave directions, depths, and structure slopes, their effects on wave overtopping were analyzed. It was found that, when the variability of wave directions is considered or the water depth decreases toward shore, wave height become smaller due to wave refraction, which yields smaller mean overtopping rate, overtopping probability and maximum overtopping volume. For the same mean overtopping rate, the expected overtopping probability increases and the expected maximum overtopping volume decreases as approaching toward shore inside surfzone.

The objective of the paper was to estimate the changes in acreages of tidal flats after the seawall construction at the Asan Bay and the Chunsu Bay from topographic maps, hydrographic charts, and Landsat TM images. The tidal floats from topographic maps published in one year differ significantly from that in the other, which appears to be attributed to the tide levels at the time of photographing. The hydrographic charts showed that tidal flats increase at rates of 22.3 ha/yr at the Asan Bay and 56.6 ha/yr at the Chunsu Bay after the dike construction. Applying the ISODATA method of unsupervised classifications for the Landsat TM images, the tidal flats were identified, and the resulting acreages for each image estimated. The resulting tidal flats increased at the rates of 21.3 ha/yr at the Asan Bay and 47.3 ha/yr at the Chunsu Bay during twelve years after the dike construction. It was found that the rates of the annual increases from the two data are very close and the differences result from the coastal lines at the charts and the TM images.

해안단애의 형성과 침식에 의한 해안선의 후퇴를 저지하기 위해 방조벽을 설치하여 해빈의 침식 변화과정에 관한 수치모의를 수행하였다. 평균수위의 상승을 동반하는 폭풍해일이 내습하는 경우 평균수위의 상승이 방조벽의 세굴을 가속화시킨다. 그러므로 본 연구는 사빈 해안에 방조벽을 설치하는 경우 해빈 침식의 거동을 예측하는데 이용할 수 있겠다.

Coloring admixture is used for take color inside and outside of mortar and concrete, differently form pigment and spray paint take color limited surface. In our country, Using the coloring admixture is very slight and regulation is not yet about it. But that is expected the increase with raising the standard of living. Especially it is used to civil structure like dam and seawall for the environment harmony. Then we observe, in this experiment, the effect of coloring admixture on the material properties of color concrete and propose the suitable mix-proportion of color concrete.
