説明
The characteristic natures of unsaturated flow in fractured rock covered with surface soil was studied by means of 3 methods: (1) field measurement of discharge rate and electric conductivity changes of ground water flowing mainly through the unsaturated zone, (2) tracer test in the field and (3) experiment by the use of idealized model of fractured rock.<BR>The experimental model is characterized by coexistence of two types of fracture system: micro fissure subsystem and macro fissure subsystem.<BR>The obtained results are as follows.<BR>(1) Electric conductivity of the infiltrated ground water decreases soon after starting of rain, and on the basis of this result, it can be thought that some part of rain infiltrate rapidly through the unsaturated zone.<BR>(2) However, tracer (salt water) put into surface soil before rain did not find in the infiltrated ground water over the long observed period.<BR>(3) This difference in responce to rain fall is, mainly due to the existence of“Seepage Path” in the unsaturated zone.<BR>(4) It has been made clear by the experiment that the seepage path is generally created in the unsaturated zone.
