In recent decades, the vast potential of entry of solid waste and landfill leachate in soil and groundwater has caused pollutant emission, and concentration in-depth become an important issue. In order to clean or prevent soil contamination, the emission and concentration of the pollutant in soil should be specified. In this study, the digital image processing technique as a new method is used to determine the pollutant concentration in soil depth. In this regard, at first, several experimental tests are done. Then, the image processing technique and numerical simulation are utilized to determine the concentration of pollutants. Experimental test results validate the results of the finite element simulation. The results indicate a good agreement between the image processing method and numerical analyses in estimating concentration. Therefore, the image processing technique can be used as a simple, useful, and time-effective method for estimating concentration in unsaturated soil.

一种利用数字图像处理技术估算非饱和土壤污染物浓度的新方法

近几十年来,固体废物和垃圾渗滤液进入土壤和地下水的巨大潜力已导致污染物排放,深度集中成为一个重要问题。为了清洁或防止土壤污染,应明确土壤中污染物的排放量和浓度。本研究将数字图像处理技术作为一种新方法用于测定土壤深度污染物浓度。对此,首先做了几个实验测试。然后,利用图像处理技术和数值模拟来确定污染物的浓度。实验测试结果验证了有限元模拟的结果。结果表明图像处理方法与数值分析在估计浓度方面具有良好的一致性。所以,
