Abstract

 Recent frequently occurring floods promote the improvement of river-discharge measurement techniques for a better river management plan. Among them are ADCPs, radar velocity meters and image techniques. The advantage of image-based technique is its safety in measurements because images can be captured from a remote place. Compared with typical techniques such as LSPIV and STIV, the proposed technique, the space-time volume velocimetry (STVV), has the advantages that it is more robust than the previous techniques and it can provide velocity vectors which are difficult in STIV. Such features were verified from several examples of field measurements.
