Factors affecting water balance and percolate production for a landfill in operation

摘要: Percolate production and precipitation data for a full-scale landfill in operation measured over 13-year period were used to evaluate the impact importance of hydrological conditions sections on percolate rates. Both active (open) closed included evaluation. A simple top cover model requiring minimum input was simulate as function section hydrology. The results showed that changes time hydrology individual (such closure or plantation trees sections) can change total by more than 100%; thus, at an be very different from same after closure. Furthermore, willow increase evapotranspiration rate thereby reducing rates up 47% compared grass cover. This process, however, depends upon availability water layer, so evaporation will less optimal during summer where soil-water contents are low.
