Groin was constructed at SANJU beach to prevent erosion of beach profile and to nourishment by passing littoral drift. As a result, in case of the left side of groin, beach profile deposition is well effectively till now, but in case of the right side of groin, severe erosion of beach profile is proceeding now. In this study, author analyzed shore-line deformation with surveying and numerical method by Pelnard-Considere one-line model. The results of analysis for the shore-line deformation in vicinity of groin are as follows: 1. Longshore current flowed from left to right direction at right side of groin and strong rip current generated between groin and jetties. 2. Construction of groin did not regard littoral drift mechanism in vicinity of fore beach sea region, as a result severe erosion generated at right side of groin.

The analysis of water level which is changed because of the construction of bridges, flood river reservation and structures etc is important factor, researching for flood plain in urbanland. In this study, the construction of flood river reservation as multiple-purpose space is planned and water level is predicted for designed discharge in the region. Also, for Nam-river Dam discharge at drier, the rating curves of water level-discharge in upstream-sections of rubber dam are prediced due to the discharge and the optimum height of rubber dam is determinated.

海雲合海濱의 平均海濱面 傾斜度에 關해 粒度分布, 波長 및 波形勾配를 求하고, 그 結果를 分析하여 海雲合海濱의 平衡狀態를 診斷하고 進行狀態를 推定하였다. The beach slope is shown to depend primarily on the size of the beach material, but also on the wave length, wave steepness. These variables are continually changing, particulary the wave dimension, the equilibrium profile of a beach is liable to change. And slope stability (profile stability) is dynamic equilibrium state, not a static one. In this report, author studied on the slope relation to chage of beach including material size, wavelength, wave steepness of the HAEUNDAE beach as a model case. With this results for the investigated values, author will predict the chage of HAEUNDAE beach profile.

1. 孤立波理論을 適用한 碎波帶內에서의 沿岸流流動分布는 포물선 分布임이 確認되었다. 2. 沿岸流 流動의 變化에 支配的인 因子는 底面摩擦임이 確認되었다. 3. 本人의 沿岸流流動分布曲線의 理論値가 徵小振幅波 適用時의 값보다 다소 큰 값을 보이고 있다. 앞으로 亂類에서의 Reynold 應力을 고려한 沿岸流流速의 變化도 계속 究明하고자 한다. In this paper, author intented to discuss the Longshorecurrents characteristics in the breakzone with the Radiation Shear Stress concept in the consideration with the effect for the Lateral Mixing Friction (Lx). And author calculated longshore-current velocity variation according to wave condition. Discussed and calculated results are as follows ; 1. The longshore-currents distribution are parabola from breaking point to shoreline by solitary wave theory. 2. Maximum velocity point exist in breakzone. 3. The bottom friction is the most factor affecting the velocity of Longshore-Currents.

海岸地形變化에 關한 調査硏究 : 海運台海濱變形과 그 豫測에 關한 硏究

梁崙模,咸契運 慶尙大學校 1980 論文集 Vol.19 No.1

The rational design of the coast protection works requires a knowledge of behaviour of the beach under natural conditions. The understanding of the relationship between the wave action on the beach and the characteristics of the beach profile produced, is thus necessary preliminarily for the analysis of the cause of beach erosion and the evaluation of the effect of projected remedial measures. Recently, coasts in the suburbs of the large cities are vanishing remarkably by the construction of seaside industrialsite, etc. As the leisure times are increase, bathbeachs become more crowded yearly than every before year. And hen, utilizers received much disorder. In this report, authors intended to investigated the geological changes and oceanographical characteristics of HAEUNDAE beach where erosion has been serious problems. Through the analysis of the investigated results, authors figured out that the main causes of the erosion at HAEUNDAE beach are wave condition and sand drift change.

The computation of the water wave forces on offshore structures is one of the primary tasks in the design of the structures. It is also one of the most difficult tasks since it involves the complexity of the interaction of waves with the structures. The Morison equation assumes the wave force to be composed of inertia and drag forces linearly added together. The purpose of this paper is to investigate the wave forces acting on the cylinderical piles. Author set up a cylinderical piles model into 2 dimensional regular wave tank with vaned wave height, water depth, and wave period, and observed wave forced. In practice the wave forces depending on wave height, water depth, and wave period were predicted through the experimental model test. It is presented a good tool to predict qualitatively the wave forces acting on the cyinderical piles.

Rapid industrial development since 1960s and the consequent increase of foreign trades result in the shortage of harbor capacity. Thus, the coastal and harbor development accompanying the construction of coastal structures like breakwaters and sea-wall have been increased. In the analysis of the wave pressure acting on the structures, the small amplitude wave theory has been frequently emp1oyed due to its mathematical simplicity. Thus, it is necessary to simulate the nonlinear wave phenomena numerically for more accurate design of coastal structures. The purpose of this paper is to investigate wave pressure in front of breakwaters by the experimental model test. Wave pressure characteristics by existence or without existence of submerged breakwaters made a conclusion that wave pressure of existence of submersed breakwaters were found to be less than those experienced in without existence of submerged breakwaters, because of wave reflection by submerged breakwaters.

Sediment characteristics on beach are the most of one element for the sandy coast process cycle. In coastal engineering region, sediment chraracteristics determined by the sediment grain size and distribution, shpe, sorting coefficient by the waves and currents etc. In this report, author investigated and analysed on plane shape of beaches and sediments characteristics, such as grain size, skewness, sorting coefficient, beach profile gradient, color of sediment at south coast islands beaches. And author will make evolution for the beach development design with data.

咸契運 慶尙大學校 1982 論文集 Vol.21 No.1

In many geologic investigation, a data sequence may be created which consist of a succession of mutally exclusive state. An example includes point-count traverse across thin section, where the state consist of the minerals noted at succeeding points. However, now our interst is in the nature of transitions from one state to another, rather than in the position of states in the sequence. We will consider techniques which sacrifice all infromation about the position of observation within the succession, but which provide in return information on the tendency of one to follow another. In this paper, author studied for the deformation of beach profile by transition matrics. And then, will understanding for the nature of the transition in beach profile's process. Used basic transition model is 6 major transition model proposed by Sonu and Beek.
