Abstract

 In Japan, the government reinforces the environmental regulations and people worry about the environmental stability of waste landfill, so the site of landfill is diversified from inland to coast near urban areas. However, as the standards of the environmental stability and the monitoring procedures are not established, the coastal landfills have been constructed and operated without a long-term evaluation of the performance.
 This paper focuses seepage control works which play an important role in coastal waste landfills. The long-term quantitative evaluation considering the degradation of the seepage control works is performed using 3-dimensional seepage and convection-dispersion analysis on the leakage behavior of waste leachate which may contain toxic substances.
 As an example of the results, a possibility that the amount of leachate leakage would increase remarkably by taking degradation of the seepage control works into consideration as compared with the ideal state where degradation of seepage control works does not advance was shown.
