| Acoustic Current Profilers (ADCP) are the only device that can measure three dimensional velocity profiles and river bed conditions even during flooding. To fully exert ADCP、it is extremely important to understand their limitations and employ peripheral devices (PDs) effectively. The limitations of ADCP originate from an assumption commonly seen in similar devices. This paper presents flow types which can be measured by ADCP with the limitations、the appropriate usage of PDs combined with ADCP、as well as few technical aspects related to obtaining water discharge values. |
