Abstract

The purpose of this study is to suggest a quantitative assessment of wetland damage considering the effects of topsoil erosion and deposition from rainfall. In the Cheoncheon Basin located upstream of the Yongdam Dam, 16 wetlands are located, but the lacustrine and small palustrine wetland were analyzed for possible damage to erosion and deposition. As a result of applying typhoon events in 2002 and 2003, the sediment load from the upper basin was the highest at 2.30% (22,548 m3) of low water capacity. The average sediment load in the mountain areas was found to be 0.03% of the low water capacity, and it was analyzed to be less damaging than the lacustrine with relatively large watershed. as a result of the model, the lacustrine wetland, where a large area is used as agricultural land, shows a high probability of sediment yield, so it is highly likely to damage the wetland by topsoil erosion.

본 연구는 강우로부터 나타나는 표토침식과 퇴적의 영향을 고려하여 습지 훼손에 대한 정량적인 평가가 가능한 방안을 제시하고자 하였다. 용담댐 상류에 위치하고 있는 천천유역은 16개의 습지가 존재하며, 습지훼손 가능성에 대한 평가는 호수형습지와 소택지를 대상으로 이뤄졌다. 2002년, 2003년에 발생한 태풍사상을 적용한 결과, 벽남제습지의 경우 상류유역에서 유입되는 토사량은 저수용량의 2.30%(22,548 m3)로 가장 높았다. 산지영역에 위치하고 있는 소택지의 평균 유입토사량은 저수용량의 0.03%로 나타났으며 비교적 넓은 유역을 가지는 호수형습지보다 훼손가능성이 낮은 것으로 분석되었다. 넓은 면적이 농경지로 사용되고 있는 호수형습지는 모형의 결과에서 토사유입량이 높은 것으로 나타나 토양침식에 의한 습지훼손 가능성이 높을 것으로 판단된다.
