| الوصف: | The effect of initial dry unit weight and type of soil on water and nitrate migration through saturated-unsaturated soil is experimentally investigated using laboratory one-dimensional model (40 mm diameter, 100 mm height) under various head boundary. The results were compared with the numerical results by using packages of finite element name SEEPW and CTRAN of GEOSLOPE software. The results show that the initial dry unit weight has a significant effect on the transport process of water and contaminant through saturated-unsaturated soils, Nitrate concentration more sensitive than water flow to change in initial dry unit weight due to variation in mechanical dispersion that affected by porosity and void ratio which depended on dry unit weight of soil. Water content and nitrate concentration was highly affected by soil type and water application boundary conditions. |
