Water flows were analysed for the filling phase and the first 4 years after closure of two types of full-scale landfill cells: 'special cells' containing mostly fly ash from municipal solid waste (MSW) incineration disposed with other special/hazardous waste, and 'biocells' (biological cells) containing co-disposed MSW and food industry sludge. The landfill cells were constructed about -1.5 m above sea level (masl) at Lomma Bay, southern Sweden. The hydrological effects of water intrusion into the special cells from surroundings and sludge moisture within the biocells were studied. HELP modelling of hydrological processes predicted delay in peaks of leachate generation from uncovered special cells following rain, which was not confirmed. Faster leachate production as a response to rainfall from special cells than from biocells was observed. It was inferred that special waste has more intensive channelling, lower water absorption and higher hydraulic conductivity than mixtures of sludge/MSW. To avoid convergence problems in modelling uncovered special cells, the use of a 5 cm deep top layer with saturated hydraulic conductivity 1.7 x 10(-3) cm s(-1), porosity 0.437, and field capacity 0.105, is suggested. |
