河川水の熱収支観測法 A Study on Heat Balance Observations of River Water 佐渡, 公明 1000060101523 中尾, 隆志 Nakao, Takashi 中尾 Nakao 隆志 Takashi application/pdf In this paper, we described the method of measuring heat balance components of river water and showed time variations in heat balance at Wakamatsu bridge in the middle reach of the Tokoro River in Hokkaido during August 10-16, 1982, as an example. The conductive heat flux through the river bed was measured by a heat flow plate buried at a specifiｃ depth as well as thermocouples set in some soil layers between the bed and the heat flow plate. Good agreement was shown between this measured bed conduction and the values calculated using Pivovarov’s method. The reflectivity one water surface and the atmospheric radiation, which were measured using one net-radiometer, two pyranometers and one thermocouple, were discussed as compared with some empirical formulas. 北見工業大学 1983-11 jpn departmental bulletin paper https://kitami-it.repo.nii.ac.jp/records/6557 北見工業大学研究報告 15 1 103 113 https://kitami-it.repo.nii.ac.jp/record/6557/files/15-1-9.pdf application/pdf 4.6 MB 2007-04-09
