Infiltration rate at the ground surface is one of the essential boundary conditions for a quantitative evaluation of groundwater flow. Conventional method for quantifying infiltration rate based on the water budget, however, includes significant uncertainties resulting from different types of quantities to be measured. In this study, focusing on a method where the infiltration rate is estimated directly from temporal changes in soil water contents in the region of interest, the measurement data was confirmed based on the 
unsaturated hydraulic tests. Then, the reliability of the measurement was verified by comparing the data to the laboratory test results and uncertainties associated with the measurements were quantified.

The soil moisture measurement method is being developed with the application of the optical fiber sensor, that is thought to be more advantageous than the conventional methods in the soil moisture measurement regarding its characteristics of multiple-point and long-distance measurement. We report the results obtained in the performance test of the optical fiber moisture metering sensor in the course where its fundamental mechanism and its principle are being developed.
