Study on using Capillary Barriers to Control the Amount of Water that Permeates Landfills

Abstract

The achievement of reclamation conditions suitable for waste stabilization is expected when controlling the amount of water permeation through the cover layer at final landfill sites. The structure of a capillary barrier, which is one method to control the amount of water permeation, was examined from the viewpoint of water permeation control. Based on this examination, it was found that analytical predictions accurately corresponded to measurement results, thus, the prediction of water permeation was quite reliable. Therefore, it was determined that capillary barriers are effective in controlling water permeation.
