裸地斜面域における雨水の浸入と地下水流出(1) ―傾斜ライシメータと土壌特性―

Abstract

In order to investigate basically the processes of rainfall infiltration, surface and groundwaterrunoff in connection with soil moisture behaviour, a slope lysimeter was constructed in 1970. Thispaper describes the detail of the lysimeter equipments, the physical characteristics of soil filled upin the lysimeter.The lysimeter has four containers of 7.0 m in length, 1.45 m in width, 1.7 m in depth and 5%in slope. Two kinds of sandy soil have been filled up in two blocks, each of which is composed oftwo containers. The physical characteristics relating to soil moisture movement were measuredby special apparatuses designed by the authors.Hydrological observations have been carried on under the bare slope and natural meteorologicalconditions since July, 1971.
