Abstract

This study analyzed the possibility of inland navigation in the Han river mouth, from Singok weir to the junction of Gongleung Stream. As a result of analysis using recent survey data and water level data, it was found that the number of days that a 250 - 400 ton class vessel can operate in the Han river estuary is less than 119 days per year. In the case of a 400 - 1,500 ton class vessel, it was found that only about 47 days per year can be operated. In this region, even in the absence of large-scale floods, the river bed continues to change significantly due to strong tides, indicating that there are limitations in securing a stable waterway. Therefore, for stable inland navigation, it is judged that continuous investigation and analysis of the possibility and stability of waterways are necessary.

본 연구는 한강 하구 신곡수중보에서 공릉천 합류점까지를 대상으로 선박 통행 가능성을 분석하였다. 최근 측량자료와 수위 자료를 이용하여 분석한 결과 한강 하구부에서 250 - 400 ton급 선박의 운행 가능일수는 연간 119일에 미치지 못하는 것으로 나타났으며 400 - 1,500 ton급 선박의 경우 연간 47일 정도만 운행 가능한 것으로 나타났다. 이 구간에서는 대규모 홍수가 없는 상황에도 강한 조석에 의해 하상이 지속적으로 크게 변화하는 것으로 나타나 안정적인 수로 확보에 한계가 있는 것으로 판단된다. 안정적인 선박 통행을 위해서는 수로 확보 가능성과 안정성에 대한 지속적인 조사와 분석이 필요할 것으로 판단된다.
