| 抄録: | A method is presented for the determination of the velocity of ground water flow by tracer method without raising the ground weter head at the injection borehole. This method consists in inserting a capsule of gauze containing tracer material to the depth of active permeable layers, which are determined by measuring the advection Joss of the concentration of tracer mixed homogeneously in the injection borehole. The merit of this method is distinctive in the case in which both the head gradient and the distance from the injection borehole to the detection borehole are small. |
