| Research Abstract |
Salt disaster, triggering salt disaster, is generated by man-made factor, such as exceeding irrigation, and natural factor, such as long-term repetition of preparation and evaporation. Therefore, the countermeasure considering complicated external impacts to the ground is needed. In this study, we developed the soil/water/air coupled F. E. simulator, which can express deformation of the ground, groundwater flow, and mass transfer within the ground. Moreover, monitoring of evaporation with lysimeter tests is conducted for improving analysis accuracy. Finally, the soil stratification resistant to salt disaster is proposed.
