Abstract

It is one of the most important research topics in hydrology to investigate the physical and statistical characteristics of precipitation in a basin. The objectives of the present paper is to show some features of precipitation observed by the raingauges installed along the mountain slopes. The relation between the rainfall amount during the observation period and the elevation of the raingauges is shown in the present paper. Further, the relation between rainfall intensity and observation period is discussed. The rainfall amount during longer than 1 day increases linearly with the elvation. The rainfall intensity dicreases with1/√T which T is the observation period.
