Landfill Process Modelling Workshop. Modelling flow to leachate wells in landfills

Al-Thani, A.A., Beaven, R.P. and White, J.K. (2004) Landfill Process Modelling Workshop. Modelling flow to leachate wells in landfills [in special issue: Landfill Process Modelling] Waste Management, 24, (3), pp. 271-276. (doi:10.1016/j.wasman.2003.11.010). (PMID:15016416).

Record type: Article


Vertical wells are frequently used as a means of controlling leachate levels in landfills. They are often the only available dewatering option for both old landfills without any basal leachate collection layer and for newer sites where the installed drainage infrastructure has failed. When the well is pumped, a seepage face develops at the entry into the well so that the drawdown in the surrounding waste will not be as great as might be expected.

The numerical groundwater flow model MODFLOW-SURFACT, which contains the functionality to model seepage surfaces, has been used to investigate the transient dewatering of a landfill. The study concludes that the position of the seepage face and information about the characteristics of the induced seepage flow field are important and should not be neglected when designing wells in landfills.
