摘要：This study investigated the applicability of the HELP model in arid areas, by construction of two 35x25 m test cells in Kahrizak landfill (longitude = 51°, 20′, latitude = 35° 27′ degrees) and monitoring the real leachate generation from each one. A set of field capacity and saturated water conductivity tests were also performed to determine basic hydrologic properties of municipal waste landfilled. A comparison was made between values calculated by HELP model and recorded values, shows that a prediction of leachate on annual basis can be done by HELP model with acceptable accuracy but when the infiltration of water to waste body increase due to leachate production, the model intents to underestimate water storage capacity of the landfill, which lead to deviation of calculated values from real ones.
