METHOD AND DEVICE FOR ESTIMATE SOIL WATER CHARACTERISTIC CURVE AND UNSATURATED PERMEABILITY OF GROUND

摘要

The method of calculating the soil moisture characteristic curve and the unsaturated water permeability curve according to an embodiment of the present invention is measured from a first sensor module composed of a moisture content sensor and a capillary absorption power sensor respectively installed in the ground of a specific site by (a) by a control unit. Receiving the generated first data; (b) calculating an amount of change in the volume function ratio and an amount of change in capillary absorption power over time based on the first data; And (c) calculating a function characteristic curve representing a relationship between the volume function ratio and the amount of change in the capillary absorption power.
