Abstract
Naturally occurring radionuclides are present in the beneath the earth at different levels and can be concentrated and increased by operations related with the oil and gas industries. NORM disposal must provide adequate protection to both human health and the environment. Leachate is the major danger posed by contemporary landfills, which is affected by weather. In this paper a leach rate simulation has been carried out using the required design of class I landfill to see the effect of climate change scenarios. Simulations are carried out using the US EPA Hydrologic Evaluation of Landfill Performance software. The inputs are 60 years generated weather data from the LARS-WG program using 30 year historical data from Bogor Climatology Station. Climate change modeling uses GCM HadGEM3-ES with RCP scenarios 2.6, 4.5 and 8.5. The annual average rainfall for RCP 2.6, 4.5 and 8.5 climate change scenarios are, 3154.27mm, 3434.47mm, and 3316.33mm respectively, lower than the site base simulation 3854.24mm. The monthly average temperature of RCP scenario is higher than site base scenario, 3.78%, 4.60%, and 6.51% respectively for RCP 2.6, 4.5 and 8.5. But the leachate rate from the barrier soil layer has no difference for each climate change scenario.
