In some places, the precipitation absorbed in the earth becomes the perched water, the level of the unconfined groundwater rises. As a result, flooding is occurring. It is necessary to observe the water level at the borehole in order to sense the rise in the water level of the groundwater level and make it useful for disaster prevention. But it is difficult to observe at multiple points. On the other hand, there are many earthing electrodes of electric facilities in the place where people are active. The value of total earthing resistance depends on the electrical conductivity of the ground. The value of electrical conductivity of the earth greatly changes when groundwater is present. Therefore, it was inspected the theory of the method to estimate a groundwater level in this paper.}, pages = {30--35}, title = {【論文】不被圧地下水水位変化に伴う水害予測のための接地抵抗変化を用いた水位推定法の理論}, volume = {35}, year = {2019} }
