Abstract

In this paper, we report monitoring results of water temperature in 24 stream sites of the Ibogawa watershed, Hyogo, Japan. The spatial distributions of the averaged water temperature in the whole watershed show that the temperature gradually increases form the upper stream to the river mouth. The spectrum analysis of temperature time series indicates that the fluctuation component with the period of 24 hour is predominant because of the solar radiation. From the comparison of the equilibrium water temperature with the observed temperature, not only the solar radiation but also other effects such as the heat advection. from the upstream may be important for water temperature prediction.
