Abstract: In this study, a developed model is established to estimate the landfill leachate quantity in arid and semi-arid regions. Based on a similar model that has been developed in Germany, a new model is proposed with regards to the weather conditions and waste characteristics in Iran. The calculated values were compared with real data that is obtained by the construction of two anaerobic test cells (32 × 50 m²) in Aradkouh landfill (longitude = 51°20′, latitude = 35°27′ degrees). In the northern cell, there was no leachate recirculation, whereas, in the southern cell, 430 m³ leachate was injected that lead to 16 m³ leachate production due to recirculation. The results show that although both cells have the same area and waste characteristics, the waste field capacity of each cell differed, due to the secondary waste field capacity which emerges thanks to recirculation, and was calculated at 32.5% and 45% in southern and northern cells, respectively.

Keywords: Aradlouh landfill; leachate recirculation; arid and semi-arid regions; waste field capacity.
