  • 하구언과 방조제의 축조와 시기를 같이 하여 목포내항 부근의 만조시 수위가 크게 상승하여 목포시 저지대 곳곳에 침수문제를 야기시키고 있으며, 저조위는 하구언 건설 이전보다 낮아져 연안해운이 발달된 목포항에서 선박의 항해에 지장을 받는 등 이중의 고통을 받고 있는 실정이다. 이와 더불어 목포구의 조류속이 건설전에 비해 급격히 감소됨에 따라 외해수와 내해수의 해수교환이 여의치 않게 되었으며, 최근 크게 문제시되고 있는 영산호의 수질과 목포시의 폐수발생량을 감안하면 장차 목포항 인근의 해수오염이 크게 우려되는 실정이다. (중략)

  • Recently, many ships such as fishing boats, cargo ships, high speed ferry boats are visiting Mokpo harbor. In particular, many marine accidents rave been occurred at this area because of the narrow channel, a thick fog, the existing of the shallow waters etc. However there is no suitable ships' routeing system which takes account of today's traffic situations in this area. This study aims at the settling of hazardous factors to mitigate the danger to vessels in mokpo harbor and to secure the safety qf maritime environment.

  • The in situ observations and the seawater analyses were conducted for 3 years from August 1996 to August 1999 in order to elucidate and evaluate seasonal variations of marine water quality and trophic state in Mokpo harbour of Korea. Compared the seasonal seawater qualities of Mokpo harbour with the OECD standards of trophic classification in parameters such as Secchi depth, dissolved inorganic nitrogen, phosphate phosphorus and chlorophyll-a, the trophic level of seawater in Mokpo harbour was evaluated to be in mesotrophic or eutrophic state through all 4 seasons and to be in eutrophic state, particularly In summer. The estimation of pollution index by eutrophication showed the seawater quality of Mokpo harbour to deteriorate and fall under the regular grades through all 4 seasons, although the seawater quality of Mokpo harbour was evaluated to be equivalent to the second or third class of the Korean seawater quality standards in view of COD values. The results of eutrophication index estimation showed the high potentiality of red tide occurrence In Mokpo harbour, particularly in summer or fall. In the light of the average atomic ratio of N/P in seawater, the limiting nutrient factor against the growth of phytoplankton was concluded to be phosphorus rather than nitrogen in Mokpo Harbour.

  • A thorough inventory of ship emissions, particularly ship's emission of in-port area is necessary to identify significant sources of exhaust gases such as NOx, SOx, PM, and CO2 and trends in emission levels over time, and reduce their serious effects on the environment and human health. Therefore, the goal of this study is to assess the volume of emissions from ships in Mokpo port, which serves as a gateway to the southwest coast of Korea, using a bottom-up methodology and data from the automatic identification system (AIS) and the Korean Port Management Information System (Port-MIS). In this work, an analysis of ship movement utilizing AIS data and an actual set of data on ship specification were gathered. By examining ship movement using AIS data, We also proposed a new approach for identifying cruising/maneuvering mode. Finally, the results were classified by ship operating mode, by exhaust gas, by ship type, and by berth, which provides a thorough and in-depth analysis of the air pollution caused by ships in Mokpo port.

  • The purpose of this study is to evaluate port use and the distribution of risk factors in 15 major ports in Korea, delineating the risk of each port after classifying the ports into four risk groups based on estimated risks. The placement of response vessels is then analyzed accordingly. Based on the results, danger was estimated to be especially high in ports where large-scale petrochemical facilities are located, such as Yeosu Gwangyang ports (1.85), Ulsan port (1.33) and Daesan port (1.25). The ports showing the next highest degree of danger were Pusan (0.95) and Incheon (0.83), which have significant vessel traffic, followed by Mokpo (0.71) and Jeju (0.49), which expanded their port facilities recently and saw an increase in large vessel traffic. Next is Masan (0.44), for which many fishing permits in the vicinity. When the relative ratios of each port were graded based on the Yeosu Gwangyang Ports, which showed the highest risk values, and risk groups were classified into four levels, the highest risk groups were Yeosu Gwangyang, Ulsan, Daesan and Pusan, with Incheon, Mokpo, Jeju, and Masan following. Pyeongtaek Dangjin, Pohang, Gunsan, and Donghae Mukho were in the mid-range danger group, and the low risk groups were Samcheonpo, Okgye, and Changsungpo. Among these, all response vessel placement ports specified by current law were above the mid-range risk groups. However, we can see that ports newly included in mid-range risk group, such as Mokpo, Jeju, and Donghae Mukho, were excluded from the pollution response vessel placement system. Therefore, to prepare for marine pollution accidents these three ports should be designated as additional response vessel placement ports.

  • The FIT(fully implicit tidal) model which adopts PCGCS (preconditioned conjugate gradient squared) method is developed and is applied to near Mokpo Harbor. Comparing computational results with observed velocities and elevations for the M$_2$ tidal constituent, agreeable correspondence is detected. The validity of the model is also proven by applying it to such areas which have narrow width (therefore showing rapid velocity), irregular topography and complex geometry. Tidal amplification phenomenon according to the constructions of seadike and sea-walls is considered by analyzing the 'filter effect' of Mokpo-ku using the model.

  • The purpose of this study is to suggest the new port development concepts in relation to the Mokpo port development. To analysis, we examine the relationship between the trade volumes which the port have and the capacities of the port facilities with 8 Korean seaport data. As a result of analysis, the trade volumes of port were found to be the major factors positively influencing the capacities of the port facilities in Korean ports. This findings shows that Mokpo port which trying to increase the trade volumes should have the new alternatives for Mokpo regional development. The new alternatives on the Mokpo Port's development are the model which constructing the Free Trade Zone(FTZ) and port city.

  • The pollution loads flowing into Mokpo harbour from land in dry case were estimated on the bases of the seasonal flow rates and the seasonal water qualities of streams and effluents located around Mokpo harbour. Average daily amount of fresh water Stowing into Mokpo harbour obtained by the inflow rate data of 4 seasons was found to be about 5.5×10/sup 6/㎥/day and annual inflow rate to be about 2×10/sup 9/㎥/year. The seasonal flow rates of effluents iron Yongsan lake were above 90% of total flow rates of all inflows in 4 seasons. The concentrations of COD, TSS, TIN and TP at 9 inflow stations Iron streams and effluents in 4 seasons were shown to be in the ranges of 2.87~42.69㎎/ℓ, 3.65~1080.32㎎/ℓ, 0.083~89.744㎎/ℓ and 0.028~6.926㎎/ℓ, respectively. The average loads of COD, TSS, TIN and TP into Mokpo harbour estimated by the data of 4 seasons were found to be about 37 ton/day, 64 ton/day, 13 ton/day and 1.2 ton/day, respectively. The loads of COD, TSS, TIN and TP into Mokpo harbour in summer were shown to be about 82 ton/day, 159 ton/day, 14 ton/day and 2 ton/day, respectively. The main source of pollution loads into Mokpo harbour was found to be the effluent of Yongsan lake.
