| Research Abstract |
This study provides a new method of groundwater exploration using groundwater aeration sound. The groundwater aeration sound (GAS) is that a kind of elastic wave generated around the vicinity of the saturated / unsaturated boundary. We conducted a survey using the existing wells in the dry grasslands of Mongolia. As the results, there was the logarithmic relationship between the GAS level and groundwater level. In addition, there was a difference in GAS distribution depending on geological conditions. With this relational equation, we investigated the GAS survey to estimate continuous groundwater level on a slope. As a result, we got a valid result on hydrogeology. Moreover, at the point where the groundwater level was shallow, there was much water-loving vegetation.
