| Experiments of continuous flow rate measurements using non-contact Doppler-type current meters were made during floods in three rivers of Japan. As a result of the study, the authors have confirmed that the Doppler-type current meters can be utilized as substitutes for the float method which has been being conventionally applied for flood flow measurements in Japan. Furthermore, it is also indicated this kind of non-contact current meter can detect the H-V loop relations during floods and the change of hydraulic conditions of the observation section such as river bed and its roughness. |
