Prediction of the contamination track in Al-Najaf city soil using numerical modelling

Abstract

Leachate generated from Municipal Solid Waste (MSW) may drain into groundwater aquifers as a consequence of rainfall, transmitted to the conterminous river system through groundwater flow and contaminate the environment. Iraq, because of the lack of accurate data and the high cost of measurement, accurate assessment of leachate generation levels has often been considered a problem. The production of leachate connects into many factors, such as the data of meteorological, levels of waste production, and requirements of design landfill, the large differences in these factors indicate that leachate modelling processes are complicated. The purpose of this paper is to predict the movement of various contaminants in landfill soil in Al Najaf city to predict the behaviour and distribution of landfill pollution in order to properly understand the distribution of contamination in these soil, to control it and to prevent groundwater contamination to predict the depth of leachate from landfill using numerical model by SEEP/W, and CTRAN/W packages from GeoStudio 2012 Software.
