摘要
PROBLEM TO BE SOLVED: To provide a method for simply deriving a soil water moving speed at once while dispensing with considerable computer resources.;SOLUTION: This soil water moving speed deriving method is a method for deriving the moving speed of water in soil. Two temperature sensors 21 and 23 and a heater 22 are aligned in the order of the temperature sensor 21, heater 22, and temperature sensor 23, in a straight line along the moving direction of the water in the soil which is a measurement place, and two temperature measurement terminals 21 and 23 are aligned within a distance allowing them to sense heat conduction based on the ON-OFF of the heater 22. The thermal diffusion coefficient k (constant) previously measured of the relevant soil is used to find thermal flux V in the relevant soil based on expression (1) expressed in the form of differentiation. This thermal flux V and the heat capacity Cs (constant) previously measured of the relevant soil are used to derive the moving speed of the water in the relevant soil based on expression (2).;COPYRIGHT: (C)2007,JPO&INPIT
