Abstract

Climate change has caused detrimental phenomena such as heavy rainfall which could aggravate soil erosion. Accordingly, it is needed to evaluate the groundwater recharge, baseflow, and soil erosion for the efficient management of water resources and quality. In this study, future climate change scenarios were applied to the H aean-myeon watershed which is a steep sloping watershed in South Korea to analyze groundwater recharge, baseflow, sediment. Also, the variation of groundwater recharge, baseflow, sediment was analyzed according to the change of slope (5 %). Simulated periods were divided into three terms (2013 ~ 2040 years, 2041 ~ 2070 years, 2071 ~ 2100 years). As a result of this study, average groundwater recharge and baseflow increased by 50 %, 42 %, and sediment decreased by 72 %, respectively. In these regards, the suggested method will positively contribute to hydro-ecosystem and reduction of muddy water at a steep sloping watershed.

기후변화로 인해 폭우 및 재해들이 일어나고 있다. 특히 강우강도가 커짐에 따라 토사유출도 심해지고 있다. 이에 따라 효율적인 수자원 및 수질 관리를 위해 지하수 함양량과 기저유출, 그리고 토사유출 현황을 평가 하는 것이 필요하다. 이에 본 연구에서는 대표적인 급경사지 유역인 양구 해안면 유역에 미래기후변화 시나리오를 적용하여 지하수 함양량, 기저유출량, 유사량을 전망하였으며, 또한 유역의 경사도를 완만하게 줄임으로서 지하수 함양량, 기저유출량, 유사량의 변화를 분석하였다. 모의 기간을 2013~2040년, 2041~2070년, 2071~2100년으로 나누었으며, 급경사지 유역보다 유역의 경사도를 완만하게 줄인 경우가 지하수 함양량이 평균 50% 증가되었으며, 기저유출량도 약 42% 증가되었다. 유사량은 급경사지 유역보다 경사도를 완만하게 줄였을 경우가 72% 유사량이 줄어드는 것으로 나타났다. 본 연구의 결과에서 보이는 바와 같이 경사도를 완만하게 적용하면 유역 내 지하수 함양량 및 기저유출량이 증가하고, 유사량을 저감 시킬 수 있는 것으로 분석되어 향후 탁수에 긍정적인 영향을 미칠 것으로 판단된다.
