土壌水分採取器を用いた実質飽和域の簡易推定法における砂質土砂の諸性質の影響

The influence of properties of sandy soil i.e., diameter and saturation level were discussed from the relationship between essentially saturated zone and sampling weight of moisture with soil moisture sampler which can be easily measured. The weight of water sampled in a saturated zone was almost constant at around 6 grams for all particle sizes. The finer the particle size, the lower the saturated water level showing the same weight of water taken as in the saturated zone as essentially saturated zone. These results show that it is possible to easily estimate the essentially saturated zone and particle size by grasping the weight of water sampled and the saturation level at several points along the beach.
