Abstract

Lateral connectivity between a main channel and a former channel plays an integral role in maintaining ecological functions of stream-floodplain ecosystems. This study virtually restored the connectivity of the former channel, which is currently isolated by channelization, in the Mangyeong River, Korea. Fish habitat improvement after the connectivity restoration was evaluated using River2D, two-dimensional depth-averaged hydraulic modeling, depending on normal and flood flow conditions. Target fish species were crucian carp (Carassius auratus), which are known as lentic species, and pale chub (Zacco platypus), known as lotic species. The weighted usable area (WUA) of the two species was increased after the connectivity restoration: the two-way connection between the main and formal channels was more effective than the one-way connection. The result of the physical habitat simulation at a flood flow condition demonstrated an increased rate of the WUA than during a normal flow condition. In particular, the WUA of pale chub increased about four times on the two-way connectivity restoration. This result suggests that habitat availability of both lentic and lotic fish species will increase after a connectivity restoration, and a two-way connectivity restoration may be more effective. In addition, the restored formal channel would function as a shelter for fish during the flood season.

하천 본류와 구하도 사이의 횡적 연결성은 하천-홍수터 생태계에서 생태적 기능을 유지하는데 매우 중요하다. 본 연구는 2차원 평균수심 유한요소 모형인 River2D를 사용하여 만경강에서 직강화로 인해 격리된 구하도의 연결성을 가상으로 복원하고 평수기와 홍수기 조건에서 어류 서식처 변화를 평가하였다. 평가 대상 어종은 정수성 어종인 붕어 (Carassius auratus)와 유수성 어종인 피라미 (Zacco platypus)를 선정하였다. 물리서식처모의 결과에 의하면, 연결성 복원 전후의 붕어와 피라미의 가중가용면적 (weighted usable area, WUA)은 복원 후에 증가하였으며 양방향 복원이 일방향 복원보다 어류 서식처 복원에 효과적이었다. 또한 가중가용면적의 증가율은 평수기보다 홍수기에 더 높았다. 특히 피라미의 경우 홍수기에 구하도의 연결성이 양방향 복원되었을 때 구하도 내의 가중가용면적이 복원 전 대비 약 4배로 크게 증가할 것으로 예측되었다. 본 연구 결과 만경강에서 본류와 구하도의 연결성이 복원되었을 때 정수성 어류와 유수성 어류의 서식처가 모두 증가할 것으로 예상되며, 일방향 복원보다 양방향 복원이 더 효과적인 것으로 나타났다. 또한 복원된 구하도는 홍수기 때 어류의 피난처 역할을 할 것으로 기대되었다.
