It is well known that salt rock layer is widely deposited under the Eurasian basement. Underground water contains weakly salt where the salt rock layer is occasionally deposited near the ground surface. Such a typical example can be seen in the northeast area of Thailand. Agricultural productivity decreases due to the salt damage of that the salty ground water level gradually rises resulting in appearance of salt crystals on the ground surface associated with annual repeat of rainy and dry seasons. This research project is intended to develop a numerical computation technique to reveal the mechanism of salt damage which will lead desertification. On the other hand, paper sludge discharged from paper manufacture causes a serious environmental problem. Such sludge can be changed to porous stable ceramic materials by burning it at 1300 degrees. This research project also aims at utilizing such materials to protect and repair the salt damage.

众所周知，欧亚大陆基底下广泛沉积着盐岩层。地下水含弱盐，盐岩层偶尔沉积在地表附近。在泰国东北部地区可以看到这样一个典型的例子。由于咸地下水位逐渐上升，导致地面上出现盐结晶，与每年的雨季和旱季重复，农业生产力下降的盐害。本研究旨在发展一种数值计算技术，以揭示盐害导致沙漠化的机理。另一方面，造纸过程中排放的造纸污泥造成了严重的环境问题。这种污泥可以通过在1300度下燃烧而变成多孔稳定的陶瓷材料。本研究也旨在利用这些材料来保护和修复盐害。
