| Outline of Final Research Achievements |
This study aims at developing the numerical salt removal model for water infiltration method to recovery a salt affected soil after Tsunami and finding out the effect of the depth of floodwater, Hw, on the salt removal performance. An indoor experiment draws the following two results; (i) The effect of Hw cannot be disregarded. (ii) The number of salt removal (fresh water flooding and drainage) times could be decreased even though mass of the fresh water is same. Also, proposed model can evaluate removal salt mass by water infiltration method. However, it is necessary to improve the model to reproduce salt movement surround culvert pipe with high accuracy.
