Abstract
In order to analyze the experimental results obtained from the model riverbed filtration performed by Ahn et al. a mathematical model was developed to simulate the flow through the lateral. The discharge rates at each section of the lateral measured by Ahn et al. were compared with the model predictions, and they matched favorably. The Manning's roughness coefficients of all the laterals employed in the study of Ahn et al. were determined using the model. Results show that the roughness coefficient becomes larger with the increase in the entrance velocity to the collector well, and that the coefficient ranges from 0.012 to 0.015 under the normal operational conditions of the riverbed filtration. Results also show that the coefficient becomes smaller as the lateral diameter increases.
