JOURNAL FREE ACCESSA perturbation solution of the Boussinesq equation under the boundary condition of multi-tide at the coast was derived for evaluating the hydraulic parameters of phreatic aquifer from tidally induced fluctuation of water table. Then, the solution was applied to estimate the hydraulic parameters of the Shiro-mama formation at the Niijima Island, Japan, by fitting the solution to the results of continuous measurements of water table fluctuations. The estimated hydraulic transmissivities from both the amplitude and the phase were comparable and consistent with the results of analyses based on Dupuit-Ghyben-Herzberg model, suggesting that the obtained values, i.e., 0.12−1.7 m2/s were reasonable.View full abstractDownload PDF (2925K)

JOURNAL FREE ACCESSMeasurements of groundwater level in boreholes and evaluations of water saturation by using amplitude domain reflectometry (ADR) method were conducted in unconsolidated ground of several meters thickness from the surface whose hydraulic conductivity was around 10−5m/s. The result showed that the water-saturated area by a direct rainfall infiltration was within depth of 1m, that the unsaturated area with moisture movement by rainfall was within depth of 3-4m, and that the water-saturated area by groundwater and capillary fringe was deeper than depth of 4m in the unconsolidated ground. The conceptual model of rainfall infiltration in the unconsolidated ground was also constructed by using data of groundwater level and water saturation.View full abstractDownload PDF (2636K)
