36 Simulating the Water Movement through the GCL Cover Using HYDRUS 1D Software Mohammad Mehdi Bideh Email mm bideh@ag iut ac ir November 2 2015 College of Agriculture Deptartment of Water Engineering Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiSupervisor M Shayannejad Email shayannejad@cc iut ac irAbstractThe amount of solid waste generated increases each year Landfill is the most common method of solid wastedisposal currently being used in many parts of the world The most common problems of the landfill site areenvironmental degradation and groundwater contamination caused by leachate produced during thedecomposition process of organic material and rain fall Most of landfill sites in developed countries have usedGeosynthetic clay liners GCLs as landfill leachate barriers to protect the environment In this article thesimulation of movement of water through the GCL cover using Hydrus 1D software In total 12 series of tests were performed to investigate the effect materials PP PET geotextiles andIsfahan Arak bentonite and mass unit area 4000 4500 5000 gr per m2 Analysis of residual errors differencesbetween the measured and simulated values was performed to evaluate the model performance based on themean absolute error MAE root mean square error RMSE coefficient of determination CD modelingefficiency EF and coefficient of residual mass CRM The outputs from the models were compared againstthe measured infiltrated water and water drained data Simulated and measured Infiltrated water and waterdrained were in excellent agreement Modeling efficiency of the drainage water model and infiltrated water are0 8029 and 0 9770 respectively The mean absolute error and root mean square error of 1 2949 and 1 4507respectively to estimate the drained water infiltrated water estimation model models 4 2359 and 4 7184 respectively The simulation results showed that although the model is a good estimate of the infiltration anddrainage systems do but the values obtained in early experiment in the laboratory with what is does not match This shows that the hydrophobic characteristics of geotextiles not consider HYDRUS 1D software Thesimulations indicate that Arak bentonite for use in geosynthetic clay liner coatings is better than landfill Keywords Geosynthetic clay liners GCL landfill HYDRUS 1D
