초록

본 논문은 국내 농업용저수지의 성층현상을 방지하고자 물순환장치를 설치하였을 때, 3차원 수리해석모델인 EFDC를 이용하여 부유물질 이송확산모의를 하였다. 이를 통해 물순환장치의 이송확산범위를 예측하고, 다양한 운전인자를 조절함으로써 최적의 운전인자를 도출하여 물순환으로 인한 내부변화의 영향을 최소화하고자 하였다. 3차원 이송확산모의 결과에 의하면, 30일 이후에 전 수층에 걸쳐 물순환이 시작되며, 100일 이후 저수지의 전체순환이 가능한 것으로 모의되었다. 또한, 연속운전보다 간헐운전이 저수지 전 구간에서 이송확산농도가 낮게 나타났으며, 안정적으로 전체순환이 일어났다. 물순환장치의 표층과 저층 혼합비율은 표층 혼합율이 높을수록 저수지 영향을 감소시킬 수 있으며, 3:1 동일조건일 경우, Case 8(50일운전:50일정지) 조건이 저수지의 내부영향을 최소화할 수 있을 것으로 나타났다.
