LandSim——地下水运动及污染质运移的数值模拟软件
LandSim是基于蒙特卡洛的随机性模型,其主要目的是评估特定填埋场的地下水保护功能。主要功能包括评价填埋场地淋溶液的渗透,污染物在包气带与饱和含水层中的自然衰减过程,还可以用来评估不同顶部及底部防护层(Clay,HDPE)和渗滤液排水系统(Leachate Drainage System)的环境性能。
LandSim uses Monte Carlo probabilistic performance assessment models constructed for new and existing landfill sites. The model essentially tracks leachate production, chemistry, migration and leakage through engineered an non-engineered structures, followed by leachate migration through the unsaturated zone to assess the ultimate impact on the aquifer.
