Abstract

A pilot-scale sand-box experiment simulating a lateral of collector well used in riverbank filtration was performed, and hydraulic head distributions along the lateral were measured according to the various drawdowns at the well. The results of this experiment were compared to the predicted values obtained using a theory previously developed by Kim in order for its validation. This theory predicts the head loss in a large-scale lateral given the loss in a small-scale one, and to have actual values for comparison, the results from a lab-scale experiment previously performed by Kim were employed. Comparing the experimental values to the extrapolated value indeed confirmed the validity of the theory. A procedure to determine the hydraulic head distribution of a practical-scale lateral was also presented applying the theory to the experimental result of this study in an effort to show the process of lateral design for riverbank filtration.

강변여과용 수평집수관을 모사하는 파일럿 규모의 모래통 실험을 수행하였으며, 다양한 출구유속에 대한 수평집수관에서의 수두분포를 구하였다. Kim이 수행한 실험실 규모의 수평집수관에서의 손실수두에 Kim이 개발한 이론 즉, 작은 규모의 수평집수관에서의 손실수두로부터 큰 집수관의 손실수두를 계산하는 방법을 적용하여 본 연구의 관측치와 비교함으로써 Kim의 이론이 타당함을 알 수 있었다. 또한, 이들의 이론을 적용하여 본 연구에서의 관측치로부터 실규모 집수관에서의 수두분포를 구하는 방안을 예를 들어 설명함으로써 강변여과의 수평집수관 설계방법을 제시하였다.
