STIV-DIEX INTEGRATED SYSTEM FOR LONG-TERM CONTINUOUS RIVER DISCHARGE MONITORING

Abstract

 In this study, we conducted a long-term monitoring for river water-level and discharge by using STIV-DIEX integrated system which authors have presented. Furthermore, hydraulic experiments is conducted in order to confirm the environment dependence. The results indicated that the automatic continuous monitoring was successful for nine monthes from the installation, and the observed water-level data are in good agreement with reference data. Although discharge were continuously observed, its value were smaller than ADCP. This result suggested that the influence of wind. The results of hydraulic experiment reveal that the reverse wind's effect is larger than that of streamwise direction wind.
