IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Real-time discharge measurement with fixed-type surface image velocimetry (fsiv) inwide rivers
Author : Seojun Kim ,Yoonsung Lim , Jihye Kim and ByungmanYoon
Surface Image Velocimetry (SIV) is a recently-developed discharge measurement instrument. It uses image processing techniques to measure the water surface velocity and estimate water discharge with given cross section. The present study aims to test a FSIV(Fixed-type Surface Image Velocimetry) at Soojeon Bridge in the Dalcheon Korea. The hardware system consists of two digital cameras, a computer, and a pressure-type water stage gauge. The images taken with the hardware system are sent to a server computer via a wireless internet, and analyzed with a image processing software (SIV software). The estimated discharges were compared with the observed discharges through the Goesan Dam spillway. The computed results showed a good agreement with the observed one, except for the night time. The maximum error reached around 15 %. Considering the low cost of the system and the visual inspection of the site situation with the images, the FSIV would be fairly good ways to measure water discharge in real time.
