| 内容記述 | Recently in our country, the groundwater was largely pumped up with increasing demand of fresh water owing to the concentration of population and the progress of industrialization. Its pumping has caused undesirable phenomena such as the subsidence of land surface and seawater intrusion into coastal aquifer and has become the serious problem for the preservation of fresh water resources. Many efforts have been paid for artificial injection of water from recharging well to solve this problem, but recharging works have not been advanced against our expectations, being impeded perhaps by the lowering of soil permeability which is not yet known clearly. The authors observed the flowrate (Darcy's velocity) of city water flowing through sand column in glass pipe and the accumulative volume of air released from that water in the column. It was found that the permeability of sand was linearly lowered with increasing air volume and that the release rate of air was higher in greater diameter of sand particles. This result will be explained by the reduction of effective porosity due to air accumulation, and may be available to artificial recharge of groundwater for estimating theoretically injection volume of water. | |||||||||
